Player Reports

  1. 1. Tyler Soderstrom | C
    Tyler Soderstrom
    Born: Nov 24, 2001
    Bats: L Throws: R
    Ht.: 6'2" Wt.: 205
    Drafted/Signed: HS--Turlock, Calif., 2020 (1st round).
    Signed By: Kevin Mello.

    Hitting: 60. Power: 60. Running: 40. Fielding: 40. Arm: 55.

    TRACK RECORD: Soderstrom surged into the top tier of the 2020 draft class after a blistering summer on the showcase circuit. His rise culminated with the Athletics drafting him No. 26 overall and signing him for $3.3 million to forgo a UCLA commitment. It was the second-largest bonus ever given to a prep catcher, behind only No. 1 overall pick Joe Mauer’s $5.1 million from the Twins in 2001. The A’s promptly sent the 18-year-old Soderstrom into a win-now environment at the alternate training site and watched their top pick hit nearly .500 with three home runs in his first week. He continued to dominate at instructional league, where he posted a .441 on-base percentage and earned raves as one of the top hitters in Arizona.

    SCOUTING REPORT: Soderstrom is regularly compared with Eric Chavez and Ben Grieve in terms of high school hitters to pass through Oakland’s system, and the A’s believe he has the potential to be better than both. Soderstrom already posts exit velocities as high as 108 mph and has an exceptionally advanced approach that belies his youth. He has the physicality reminiscent of a college pick, but there’s more physical projection to go and it’s easy to envision 30-home run potential with loads of walks and a high OBP. Hardly an all-or-nothing slugger, Soderstrom has a polished lefthanded swing and projects to be a plus hitter. Soderstrom is much less polished defensively behind the plate and mostly succeeded on raw ability as a prep. His skills were tested immediately at the alternate site and he struggled at times, especially blocking and receiving. Still, Soderstrom shows above-average arm strength, solid athleticism and a desire to improve. His father Steve was drafted sixth overall by the Giants in 1993 and pitched one season in the majors. He instilled the work ethic and drive needed to succeed in his son. The A’s labeled Soderstrom a “baseball rat” with a meticulous work ethic and say it’s too early to consider a move off catcher. He quickly gained the respect of veterans at Oakland’s alternate site and picked up a pair of nicknames: “The Kid” and “The GOAT” after his hot start.

    THE FUTURE: Soderstrom’s bat is advanced to the point Oakland believes he could jump straight to high Class A in 2021. He’s more likely to begin at low Class A, which would put less stress on his defense. The A’s will give Soderstrom every chance to develop as a catcher, but a future move to a corner infield or outfield spot can’t be ruled out, especially if it allows Soderstrom to jump on a potential fast track to Oakland.

  2. 2. A.J. Puk | LHP
    A.J. Puk
    Born: Apr 25, 1995
    Bats: L Throws: L
    Ht.: 6'7" Wt.: 238
    Drafted/Signed: Florida, 2016 (1st round).
    Signed By: Trevor Schaffer.

    Fastball: 80. Slider: 70. Changeup: 50. Curveball: 45. Control: 45.

    TRACK RECORD: For all of Puk’s tantalizing ability, he has not been able to stay healthy since the Athletics drafted him sixth overall in 2016. Puk had Tommy John surgery and missed all of the 2018 season, briefly returned in 2019 and made his major league debut, then missed all of 2020 with a pair of left shoulder strains. He was shut down in September and had shoulder surgery after the season.

    SCOUTING REPORT: Puk showed his upside when the A’s deployed the 6-foot-7 lefty out of their bullpen in 2019 while chasing a playoff spot. His fastball sits 96-100 mph and explodes on hitters with unique angle and impressive extension out of his imposing frame. He pairs it with a vicious upper-80s power slider that dives at the back foot of righthanded hitters, and he’s gaining confidence in his burgeoning changeup. Puk also features a low-80s curveball that flashes average. Even with just fringe-average control, he generates a ton of whiffs—12.9 strikeouts per nine innings in the minors—and uncomfortable at-bats. Health remains Puk’s biggest obstacle. He’s thrown just 194.1 innings combined in five professional seasons.

    THE FUTURE: The A’s hope Puk will be ready for spring training following his surgery. Injuries have clouded his future, but his arm is too good to give up on.

  3. 3. Daulton Jefferies | RHP
    Daulton Jefferies
    Born: Aug 2, 1995
    Bats: L Throws: R
    Ht.: 6'2" Wt.: 185
    Drafted/Signed: California, 2016 (1st round supplemental).
    Signed By: Jermaine Clark.

    Fastball: 55. Slider: 50. Changeup: 60. Control: 70.

    TRACK RECORD: Jefferies battled shoulder woes his final year in college, but the Athletics still drafted him 37th overall from California. He continued to struggle with injuries in pro ball and missed most of 2017 and 2018 after having Tommy John surgery. Jefferies rebounded with a dominant 2019 season that included 93 strikeouts against just nine walks as he rose to Double-A. He turned in an impressive summer at the alternate training site in 2020 and was rewarded with his first big league callup in mid September.

    SCOUTING REPORT: An athletic but undersized righty, Jefferies boasts an impressive fastball/changeup combination and peppers the strike zone with plus command. His fastball sits 92-95 mph as a starter and 94-97 in short bursts, and he locates it deftly to both sides of the plate. Jefferies’ plus changeup is his jewel and can make hitters look foolish when it bottoms out. His breaking stuff is less refined—his average slider is sometimes mistaken for a cutter—but can play up because of his command.

    THE FUTURE: Building innings and maintaining health is the last step of Jefferies’ progression. He did that successfully at the alternate site in 2020 and should compete for a rotation spot in 2021.

  4. 4. Robert Puason | SS
    Robert Puason
    Born: Sep 11, 2002
    Bats: B Throws: R
    Ht.: 6'3" Wt.: 165
    Drafted/Signed: Dominican Republic, 2019.
    Signed By: Amauris Reyes.

    Hitting: 50. Power: 50. Running: 60. Fielding: 60. Arm: 70.

    TRACK RECORD: The Athletics signed Puason for $5.1 million out of the Dominican Republic in 2019, which tied the Yankees’ Jasson Dominguez for the largest bonus that signing period. The coronavirus pandemic thwarted Puason’s professional debut, but the A’s brought him to their alternate training site in 2020 as one of just three teenagers alongside a mostly older, win-now group.

    SCOUTING REPORT: Puason is tooled up in a way that makes him easy to dream on. He’s a twitchy athlete with a wiry, projectable body and has shown a knack for barreling the ball from both sides of the plate. His long levers and projectable frame suggest more power is on the way, too. The A’s believe Puason can stick at shortstop in the long run, aided by his athletic ability and 70-grade arm, and he’s a plus runner now. While his tools are evident, it’s also clear Puason is still a ways away. He struggled at times with the speed of the game at both the ATS and during instructional league. Puason has worked to improve his English since coming to the U.S., including taking classes at Arizona State.

    THE FUTURE: The alternate site was a helpful, eye-opening experience for the 17-year-old Puason. He’ll look to take all he learned into his pro debut in 2021.

  5. 5. Logan Davidson | SS
    Logan Davidson
    Born: Dec 26, 1997
    Bats: B Throws: R
    Ht.: 6'3" Wt.: 185
    Drafted/Signed: Clemson, 2019 (1st round).
    Signed By: Neil Avent.

    Hitting: 45. Power: 55. Running: 55. Fielding: 55. Arm: 60.

    TRACK RECORD: Davidson displayed big tools but struggled to consistently hit at Clemson. The Athletics drafted him 29th overall in 2019 and sent him to short-season Vermont, where he hit .239/.345/.332 in 54 games to further raise questions about his hitting ability. But Davidson arrived at the alternate training site in 2020 with increased physicality and took some of the biggest strides of anyone.

    SCOUTING REPORT: The switch-hitting Davidson has impressive tools with above-average raw power, above-average speed, plus arm strength and excellent throwing accuracy. The question has always been his bat. Davidson has been dogged about his ability to hit with wood dating back to an unimpressive Cape Cod League stint, and there is length in his swing that leads to swings and misses. Davidson displays solid pitch recognition, however, and the A’s were impressed with his approach at the alternate site, generating hopes he can be a fringe-average hitter and access enough of his power to play every day. A taller shortstop, Davidson worked to clean up his actions and has the athleticism to stick at the position. He also played second base and third base at the alternate site.

    THE FUTURE: The A’s was encouraged by Davidson’s gains in a disjointed 2020, particularly hitting from the left side. He is set to make his full-season debut in 2021.

  6. 6. Nick Allen | SS
    Nick Allen
    Born: Oct 8, 1998
    Bats: R Throws: R
    Ht.: 5'8" Wt.: 166
    Drafted/Signed: HS--San Diego, 2017 (3rd round).
    Signed By: Anthony Aliosi

    Hitting: 50. Power: 30. Running: 60. Fielding: 70. Arm: 60.

    TRACK RECORD: Allen earned a reputation as a defensive wizard as an amateur and signed with the Athletics for $2 million as a third-round pick in 2017, nearly triple the slot amount. He began to progress offensively at high Class A Stockton in 2019 before a high ankle sprain wiped out the second half of his season. Allen returned healthy in 2020 and spent the summer at the alternate training site in San Jose before finishing at instructional league.

    SCOUTING REPORT: One of the top defensive shortstops in the minors, Allen is a Gold Glove-type caliber defender who was nicknamed “Magic Man” by his coaches in Stockton. He is a twitchy, instinctive defender who glides to the ball, has superb hands, covers a wide range with his plus speed and has a plus, accurate arm to convert every play. The 5-foot-8 infielder fights a glove-only perception and led the Cal League in doubles before his season-ending injury in 2019. Allen has good hand-eye coordination, and the A’s have worked with him to avoid chasing power—and fastballs up in the zone—and instead focus on a gap-to-gap approach, using fellow undersized infielder David Fletcher as a blueprint.

    THE FUTURE: How Allen progresses as a hitter will determine whether he becomes a slick-fielding backup or something more. He is slated to begin the 2021 season in Double-A.

  7. 7. Luis Barrera | OF
    Luis Barrera
    Born: Nov 15, 1995
    Bats: L Throws: L
    Ht.: 6'0" Wt.: 205
    Drafted/Signed: Dominican Republic, 2012.
    Signed By: Raymond Abreu.

    Hitting: 50. Power: 45. Running: 60. Fielding: 55. Arm: 60.

    TRACK RECORD: Signed out of the Dominican Republic in 2012, Barrera is on the doorstep of the majors after a slow climb through the system. A shoulder injury cut his 2019 season short at Double-A Midland, but he returned healthy in 2020 and was one of the Athletics’ top standouts at the alternate training site. He hit nearly .450 in camp at San Jose and won the program’s batting title on the final day.

    SCOUTING REPORT: Barrera is a bit of a throwback as a dynamic slasher with a fervent passion for the game. He is a line drive-oriented hitter, though the A’s believe he has 15-home run potential with a slightly altered approach. Barrera is aggressive, sometimes to a fault, but he makes enough contact to make it work. The A’s believe he has developed a bit more selectivity. Barrera’s plus speed shows up both on the basepaths and in the outfield, where he’s an above-average defender with a strong arm who could play all three positions. Consistency was the missing ingredient for Barrera, but A’s officials say they saw much more of it at the alternate site.

    THE FUTURE: Oakland’s starting outfield mix is mostly set entering 2021. Barrera could force his way into at least a part-time role if he carries his momentum into spring training.

  8. 8. Pedro Pineda | OF
    Pedro Pineda
    Born: Sep 6, 2003
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 180
    Drafted/Signed: Dominican Republic, 2021

    TRACK RECORD: Dominican center fielder Pedro Pineda stood out early in the scouting process as one of the top players in the 2020 international class while training with Nube. The A’s made him their top international target in the class.

    SCOUTING REPORT: Pineda has a strong but lean, broad-shouldered frame (6-foot-1, 180 pounds) with physical projection remaining and has one of the best combinations of power and speed for a 2020 international prospect. He's a quick-twitch athlete with explosive actions in the batter's box and in the field, showing plus-plus speed at his best. His barrel whips through the zone with excellent bat speed, generating plus raw power that could still tick up as he adds on more strength. Pineda shines in a workout setting and scouts highest on him saw him perform well against live pitching. There were times when his swing had extra length and loop to the ball, though he has worked to cut down on that to improve his bat path.

    FUTURE: Pineda has the speed and above-average arm strength to project in center field as long as he can maintain most of his speed and athleticism once he packs on more size.

  9. 9. Greg Deichmann | OF
    Greg Deichmann
    Born: May 31, 1995
    Bats: L Throws: R
    Ht.: 6'2" Wt.: 190
    Drafted/Signed: Louisiana State, 2017 (2nd round).
    Signed By: Kelcey Mucker.

    Hitting: 40. Power: 60. Running: 50. Fielding: 50. Arm: 55.

    TRACK RECORD: Bizarre injuries have plagued Deichmann since 2017, when he was hit in the face by a pitch as a junior at Louisiana State. He dealt with a combination of hamate, wrist and shoulder injuries in 2018 and 2019, but was healthy for the 2019 Arizona Fall League and hit nine homers in 23 games. That was enough for the Athletics to bring Deichmann to their alternate training site in 2020, and they added him to their 40-man roster after the season.

    SCOUTING REPORT: Deichmann’s carrying tool is his plus raw power from the left side. He has the bat speed and lower body strength to hit 25-30 home runs in the majors, but it will likely come with a low average and elevated strikeout rate. Scouts have been concerned about Deichmann’s grooved swing since college, and he hit just .219 with a 30% strikeout rate at Double-A in 2019. Deichmann simplified his movements and made mechanical adjustments in 2020 to restore some athleticism to his swing in hopes of getting to his plus raw power more frequently. Defensively, Deichmann projects to be an average right fielder with an above-average arm.

    THE FUTURE: The A’s were encouraged by Deichmann’s performance at the alternate site. Now he needs consistent at-bats—and to control the strike zone better—to build on it.

  10. 10. James Kaprielian | RHP
    James Kaprielian
    Born: Mar 2, 1994
    Bats: R Throws: R
    Ht.: 6'3" Wt.: 225
    Drafted/Signed: UCLA, 2015 (1st round).
    Signed By: Bobby DeJardin (Yankees).

    Fastball: 55. Slider: 55. Changeup: 50. Curveball: 50. Control: 55.

    TRACK RECORD: That Kaprielian pitched in the majors for the first time in 2020 is a feel-good story in itself. A 2015 first-round pick of the Yankees who was traded to Oakland in the Sonny Gray deal, Kaprielian missed most of the 2016 season with a flexor strain and all of 2017 and 2018 recovering from Tommy John surgery and a subsequent bout with shoulder soreness. He returned in 2019, albeit under a monitored workload, and opened 2020 at the alternate training site. He received his first callup on Aug. 16 and made two appearances out of the Athletics’ bullpen.

    SCOUTING REPORT: Kaprielian’s stuff continues to inch toward a return to form, though it’s still not where it was coming out of college. His fastball is back up to 93-95 mph as a starter and averaged 95 in relief. While his secondaries haven’t fully returned, he has the most trust in his above-average 85-86 mph slider with tight shape. Kaprielian’s curveball and changeup also show average potential, and he throws everything for strikes with above-average control. Kaprielian’s delivery remains effortful, leading to long-term health concerns.

    THE FUTURE: The A’s are eager to see what Kaprielian looks like in 2021 now that his stuff is on the mend. He can reach his back-of-the-rotation potential only if health permits.

  11. 11. Brayan Buelvas | OF
    Brayan Buelvas
    Born: Jun 8, 2002
    Bats: R Throws: R
    Ht.: 5'11" Wt.: 155
    Drafted/Signed: Colombia, 2019.
    Signed By: Tito Quintero.

    TRACK RECORD: The A's invited three teenagers to their alternate training site: Tyler Soderstrom, their 2020 first-round pick; Robert Puason, their $5.1 million international signing in 2019; and Buelvas. Unlike his contemporaries, Buelvas arrived with considerably less pedigree after signing out of Colombia for just $100,000. But all he's done is impress since then, including posting a .300/.392/.506 line as a 17-year-old in the Rookie-level Arizona League in 2019.

    SCOUTING REPORT: Buelvas does everything well despite lacking an obvious carrying tool. He's an instinctual player with an advanced approach for such a young hitter. Buelvas' 5-foot-11 frame has room for projection, although the A's don't envision much raw power. He has shown a penchant for finding the barrel and taking competitive at-bats against more experienced pitching. Buelvas' arm is average now, with a chance to reach above-average, and his speed gives him a shot to stick in center field. He didn't post gaudy statistics at either the alternate site or instructional league, but the A's love his passion for the game, work ethic and competitiveness.

    THE FUTURE: The A's trust Buelvas' makeup enough to keep pitting him against older competition. Starting 2021 at low Class A isn't out of the question.

  12. 12. Austin Beck | OF
    Austin Beck
    Born: Nov 21, 1998
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 200
    Drafted/Signed: HS--Lexington, N.C., 2017 (1st round).
    Signed By: Neil Avent.

    TRACK RECORD: The A's drafted Beck sixth overall in 2017, banking on his athleticism despite a torn ACL that wiped out his senior showcase summer. After a solid if unspectacular first full season in 2018 at low Class A Beloit, a quad injury limited him to 85 uneven games at high Class A Stockton in 2019. Beck was not invited to the alternate training site in 2020 but did accrue at-bats during the fall at instructional league.

    SCOUTING REPORT: Beck boasts impressive athleticism across the board, highlighted by his potential plus raw power, plus arm strength and plus speed, the latter of which allows him to play an above-average center field. Beck has lightning-fast hands at the plate, which can sometimes work against him when he struggles to keep his bat in the strike zone long enough to make contact. Beck made adjustments to his swing in search of more launch angle which, combined with subpar pitch recognition, led to a 34% strikeout rate with Stockton in 2019.

    THE FUTURE: Beck hasn't lived up to his draft status, but he has consistently been young for his level and didn't have a long track record against top pitching as an amateur. He's in need of consistent at-bats after a lost 2020.

  13. 13. Jeff Criswell | RHP
    Jeff Criswell
    Born: Mar 10, 1999
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 225
    Drafted/Signed: Michigan, 2020 (2nd round).
    Signed By: Rich Sparks.

    TRACK RECORD: Criswell's stuff intrigued teams as a high schooler, but most wanted to see him go to school and add strength. He immediately stepped in as a high-leverage reliever at Michigan as a freshman, helped the Wolverines to the College World Series as a sophomore and appeared as their No. 1 starter in the shortened 2020 season. The A's drafted Criswell in the second round in 2020 and signed him for a $1 million bonus. His father, Brian, was drafted by the A's in 1984 and reached Double-A.

    SCOUTING REPORT: A physical righty with impressive arm strength, Criswell already has one of the loudest arsenals in the A's system. His fastball sat at 95 mph and touched 98 in instructional league. He throws both a power curveball and a slider that flash plus and pairs them with a changeup that has average potential. Criswell has long faced reliever concerns because of his effortful delivery and spotty control--he walked 4.5 batters per 9 innings in college--but the A's were impressed with his analytical aptitude, experience working with high-speed video and willingness to make changes to his delivery.

    THE FUTURE: Criswell will need to hone in on his delivery to stay on a starter track. The A's intend to leave him in the rotation for now.

  14. 14. Junior Perez | OF
    Junior Perez
    Born: Jul 4, 2001
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 180
    Drafted/Signed: Dominican Republic, 2017.
    Signed By: Felix Perez/Trevor Schumm (Padres).

    TRACK RECORD: The Padres signed Perez for $300,000 in 2017, banking on power potential once he filled out his 6-foot-1 frame. He showed that power as a 17-year-old in the Rookie-level Arizona League in 2019, batting .268/.349/.512 with 11 homers in 209 at-bats. The A's took notice and acquired Perez as the player to be named later in a trade for Jorge Mateo.

    SCOUTING REPORT: Perez's ability to make adjustments in the Arizona League impressed the Padres. He stopped chasing as many pitches and did more damage as the year went on, posting a .283/.345/.572 line over his final 36 games while hitting 10 of his 11 homers. He will swing and miss, but not at a disqualifying level for a player his age. His physicality leaves room to dream on even more power to come. Defensively, Perez has experience at all three positions, but he is likely destined for a corner as he continues to mature and slow down.

    THE FUTURE: Perez should reach low Class A at some point in 2021. He'll team with Brayan Buelvas to give the A's a pair of exciting young outfielders in Stockton's lineup.

  15. 15. Jordan Weems | RHP
    Jordan Weems
    Born: Nov 7, 1992
    Bats: L Throws: R
    Ht.: 6'3" Wt.: 175
    Drafted/Signed: HS-- Columbus, Ga., 2011 (3rd round).
    Signed By: Tim Hyers (Red Sox).

    TRACK RECORD: The Red Sox drafted Weems as a high school catcher in 2011. Five years later, after having posted a .568 OPS through 1,027 at-bats, Boston converted him to pitching. Weems stayed in the Red Sox system through 2019 and reached Triple-A Pawtucket before signing a minor league deal with the A's after the season. He made the A's bullpen out of summer camp and appeared in nine games, posting a 3.21 ERA.

    SCOUTING REPORT: Strictly a reliever, Weems employs a fastball-heavy approach and throws it nearly two-thirds of the time. It's an above-average fastball that sits 95-96 mph with more rise than the average MLB fastball thrown at that velocity. He pairs it with an 86 mph changeup that gets swings and misses from lefthanded hitters and an 85-86 mph slider than handles righties. Weems hides the ball well, adding some deception, and you can't miss his Noah Syndergaard-esque long blonde hair. His control is belowaverage, but he throws enough strikes in the bullpen.

    THE FUTURE: Depending on how the A's proceed with free agents Liam Hendriks, Joakim Soria and Yusmeiro Petit, Weems could be in line for high-leverage relief opportunities in 2021. He should be a solid middle reliever at the very least.

  16. 16. Austin Allen | C
    Austin Allen
    Born: Jan 16, 1994
    Bats: L Throws: R
    Ht.: 6'2" Wt.: 220
    Drafted/Signed: Florida Tech, 2015 (4th round).
    Signed By: William Bosque (Padres).

    TRACK RECORD: The A's acquired Allen from the Padres after the 2019 season for Jurickson Profar and installed him as their backup catcher. Allen hit at least .280 with 20 homers every year from 2017-19 in the minors, but he struck out 14 times in 32 plate appearances with Oakland and was optioned to the alternate training site in August.

    SCOUTING REPORT: A powerful slugging type dating back to his days at Division II Florida Tech, almost all of Allen's value is tied to his bat. He regularly gets to his lefthanded power, mostly to the pull side, and has solid timing and feel to hit. He's long been dogged by concerns over his defense--namely his mobility and game-calling --and projects as a below-average defender at best. His slow transfer and below-average arm lead opponents to run on him at will.

    THE FUTURE: The addition of the 26th roster spot helps Allen, who can play first base in a pinch and provides lefthanded thump off the bench. He will again compete for a backup role behind Sean Murphy in 2021.

  17. 17. Jordan Diaz | 3B
    Jordan Diaz
    Born: Aug 13, 2000
    Bats: R Throws: R
    Ht.: 5'10" Wt.: 175
    Drafted/Signed: Colombia, 2016.
    Signed By: Jose Quintero.

    TRACK RECORD: Oakland signed Diaz for $275,000 during the 2016 international signing period on the strength of his bat. He made his professional debut as a 16-year-old, slowly worked his way through the lower levels and posted a respectable .264/.307/.430 slash line as a teenager in the college-heavy New York-Penn League in 2019.

    SCOUTING REPORT: Diaz has always possessed hitter-ish qualities dating back to his days as an amateur in Colombia. He has natural bat-to-ball skills and generates a ton of hard contact. He has a thicker build and is close to maxed out physically, inviting questions about both his power potential and ability to stick at third base, where he shows off an average arm but inconsistent footwork. The A's want to see Diaz improve his focus and approach, hoping he can turn in quality at-bats on a more consistent basis.

    THE FUTURE: Diaz internally draws comparisons to Renato Nunez, another A's international signee who flourished into a power-hitting, everyday player with Baltimore. Diaz will still be just 20 years old in 2021 and should begin the year at low Class A.

  18. 18. Grant Holmes | RHP
    Grant Holmes
    Born: Mar 26, 1996
    Bats: L Throws: R
    Ht.: 6'0" Wt.: 224
    Drafted/Signed: HS--Conway, S.C., 2014 (1st round).
    Signed By: Lon Joyce (Dodgers).

    TRACK RECORD: Holmes arrived in the A's system following a 2016 trade that sent Rich Hill and Josh Reddick to the Dodgers. He missed almost all of 2018 with a right shoulder injury, but returned to Double-A Midland in 2019 and gained momentum as the season progressed. He spent 2020 at the alternate training site in San Jose.

    SCOUTING REPORT: Stuff has never been an issue for Holmes. He attacks hitters with a heavy 92-94 mph fastball that generates plenty of ground balls and a power curveball that draws plus grades and is among the best in Oakland's system. He recently added a cutter and also throws a changeup, which are both at least average, and all of his stuff plays up in shorter outings. But hitters have a surprisingly easy time squaring Holmes up, leading the A's to tinker with his long-armed delivery and sequencing in the hopes of adding more deception. So far it's yielded mixed results. His control is fringe-average.

    THE FUTURE: Holmes should start 2021 in the rotation at Triple-A. He could ultimately be better suited for a spot in Oakland's bullpen if he doesn't display better deception and command.

  19. 19. Tyler Baum | RHP
    Tyler Baum
    Born: Jan 14, 1998
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 195
    Drafted/Signed: North Carolina, 2019 (2nd round).
    Signed By: Neil Avent.

    TRACK RECORD: Baum was a three-year starter at North Carolina before the A's made him a secondround pick in 2019 and signed him to a $900,000 bonus. He posted a 4.70 ERA over 30.2 innings for short-season Vermont after signing and was assigned to the alternate training site in 2020.

    SCOUTING REPORT: Baum was lights out his first week of the alternate site, running his fastball up to 96 mph and stymying older A's hitters. But his stuff faded over the duration of camp, leading the A's to wonder if he simply ran out of gas. When he's on, Baum features a 92-94 mph fastball with plenty of movement. His curveball has enough shape and tightness to project as a potential out-pitch, but it sometimes blends with his average slider. He also flashes an average changeup. Baum worked to cut his walk rate in college and carried those improvements over to pro ball, but he still has fringy control and his command remains a concern.

    THE FUTURE: Baum is one of many A's pitching prospects toeing the starter vs. reliever line. The A's will look for him to iron out his velocity and command fluctuations in 2021.

  20. 20. Kyle McCann | C
    Kyle McCann
    Born: Dec 2, 1997
    Bats: L Throws: R
    Ht.: 6'2" Wt.: 217
    Drafted/Signed: Georgia Tech, 2019 (4th round).
    Signed By: Jemel Spearman.

    TRACK RECORD: The A's drafted McCann (no relation to Brian) out of catching factory Georgia Tech in 2019, where he started behind the plate as a junior after spending his first two seasons at first base in deference to Joey Bart. McCann flashed plenty of power to go along with plenty of strikeouts in his pro debut with short-season Vermont in 2019. He was assigned to Oakland's alternate training site in 2020, where he was aided by the tutelage of veteran catcher Carlos Perez.

    SCOUTING REPORT: The A's labeled McCann as one of their biggest risers at the alternate site, a welcome development after he struggled mightily in his pro debut. Massive all-fields power is McCann's calling card, albeit with limited contact. He has a tendency to get pull-happy at times and projects as no more than a below-average hitter. It was strides he made defensively that impressed the A's the most. He showed an increased attention to detail and a willingness to improve his blocking, mobility and receiving. Those developments lead the A's to believe he could still develop into an adequate defensive catcher. He also plays an average first base right now.

    THE FUTURE: The 2021 season will be revealing for McCann. He still must prove he's the player the A's saw at the alternate site instead of the one who floundered in his pro debut.

  21. 21. Michael Guldberg | OF
    Michael Guldberg
    Born: Jun 22, 1999
    Bats: R Throws: R
    Ht.: 6'0" Wt.: 171
    Drafted/Signed: Georgia Tech, 2020 (3rd round).
    Signed By: Jemel Spearman.

    TRACK RECORD: The A's drafted Guldberg, a favorite of area scout Jemel Spearman, in the third round of the shortened 2020 draft. Missed developmental time because of a 2018 shoulder injury and the 2020 coronavirus pandemic meant Guldberg had less track record than a typical college hitter, but he did rank second in the Atlantic Coast Conference with a .355 batting average as a sophomore. He was a top performer at instructional league before a minor leg injury shut him down.

    SCOUTING REPORT: The A's believe Guldberg can stick in center field despite playing mostly left field in college. He's a quick-twitch, wiry athlete who pairs quality defensive instincts with his plus running ability. He has experience playing second base and the A's may eventually get him occasional reps there, too. Guldberg takes a contact-oriented approach to the plate from the right side and has impressive bat speed. He lacks physicality but the A's say he showed sneaky raw power in batting practice.

    THE FUTURE: Guldberg fits the mold of a versatile utilityman. He'll make his pro debut in 2021.

  22. 22. Jeremy Eierman | SS
    Jeremy Eierman
    Born: Sep 10, 1996
    Bats: R Throws: R
    Ht.: 6'0" Wt.: 205
    Drafted/Signed: Missouri State, 2018 (2nd round supplemental).
    Signed By: Al Skorupa.

    TRACK RECORD: Eierman surged up draft boards as a sophomore at Missouri State, but his power numbers dropped as a junior and led him to fall to the supplemental second round. Eierman's offensive regression has continued in pro ball. He hit just .208/.270/.357 with 177 strikeouts at high Class A Stockton in 2019, the fourth-most strikeouts in all of minor league baseball.

    SCOUTING REPORT: It's easy to take notice of Eierman's plus raw power in batting practice, but an inability to make consistent contact has hampered his ability to unlock that power regularly. Eierman has tinkered with his mechanics often over the last three years and Oakland spent time remaking both his approach and his stride. The early returns were encouraging--he walked as much as he struck out in a limited instructional league sample size--but there is still concern over his ability to make consistent contact. Even with a more mature, filled-out frame, Eierman is an above-average defender with a plus arm capable of playing multiple infield positions.

    THE FUTURE: A return to high Class A could be in order for Eierman, where the A's hope he continues to display a better hitting approach.

  23. 23. Skye Bolt | OF
    Skye Bolt
    Born: Jan 15, 1994
    Bats: B Throws: R
    Ht.: 6'2" Wt.: 187
    Drafted/Signed: North Carolina, 2015 (4th round).
    Signed By: Neil Avent.

    TRACK RECORD: Bolt made his major league debut in 2019, hitting a double in 10 at-bats. He wasn't a September callup initially and only got the nod after an injury to Mark Canha. He spent 2020 at the alternate training site in San Jose.

    SCOUTING REPORT: A switch-hitter more effective from the left side, Bolt teases with his athletic skill set but has yet to fully capitalize on it. He has a keen eye at the plate and bettered his strikeout rates as he moved through minor leagues, helping to mitigate his fringe-average hit tool. Defensively, Bolt can comfortably play any outfield position, aided by his above-average speed and arm strength. He has struggled with injuries since the A's drafted him in 2015 out of North Carolina.

    THE FUTURE: Bolt faces stiff competition in pursuit of a bench role in Oakland's outfield. His legs and glove give him a shot.

  24. 24. Colin Peluse | RHP
    Colin Peluse
    Born: Jun 11, 1998
    Bats: R Throws: R
    Ht.: 6'3" Wt.: 240
    Drafted/Signed: Wake Forest, 2019 (9th round).
    Signed By: Neil Avent.

    TRACK RECORD: Peluse epitomizes a player who worked diligently despite the lack of structured player development in 2020. Not assigned to the alternate training site, Peluse committed to an at-home workout plan tailored to increase his leg strength and added 10 pounds of muscle. He arrived at instructional league showing significant velocity gains, much to the A's surprise.

    SCOUTING REPORT: Peluse's fastball sat 96 mph and touched 98 at instructs, a marked increase from his low-90s readings in college. His slider was already a plus pitch, showing late life and more drop than a typical slider. His changeup is firm, sitting at 88-89 mph, and the A's worked to soften it a bit during instructional league. Peluse already possessed one of the better deliveries among Oakland's starting pitching prospects and showed solid command and control during his time at Wake Forest, walking 3.18 batters per nine innings.

    THE FUTURE: The A's hope Peluse sustains his velocity gains. He'll try to show he can in his first taste of full-season ball in 2021.

  25. 25. Drew Millas | C
    Drew Millas
    Born: Jan 15, 1998
    Bats: B Throws: R
    Ht.: 6'2" Wt.: 205
    Drafted/Signed: Missouri State, 2019 (7th round).
    Signed By: Steve Abney.

    TRACK RECORD: Millas was considered one of the top defensive college catchers in the 2019 draft class, but puzzling offensive struggles hindered his stock and dropped him to the seventh round. A subsequent injury to the UCL in his throwing arm combined with a blood clotting issue in his right armpit postponed his professional debut. Millas arrived at instructional league in 2020 fully healthy and immediately impressed the A's.

    SCOUTING REPORT: Millas was a three-sport star in high school, also playing quarterback and point guard, and it shows behind the plate. He's an agile defender, a solid receiver and displays prototypical leadership skills, making him a favorite for pitchers to throw to. His arm is above-average even despite the injury. The switch-hitting Millas is a better hitter from the left side, where he projects as an average hitter with solid bat speed, although there were swing-and-miss concerns in college. His power is below-average and limits the offensive impact he projects to make.

    THE FUTURE: Millas' glove will help him move through Oakland's system. How far his bat comes along will ultimately determine how far he rises.

  26. 26. Miguel Romero | RHP
    Miguel Romero
    Born: Apr 23, 1994
    Bats: B Throws: R
    Ht.: 6'0" Wt.: 202
    Drafted/Signed: Cuba, 2017.
    Signed By: J.C. de la Cruz.

    TRACK RECORD: The A's signed Romero from Cuba in 2017 as a 23-year-old. He has primarily worked out of the bullpen and posted a 3.96 ERA in 45 appearances at Triple-A Las Vegas in 2019. He spent 2020 at the alternate training site in San Jose, where he showcased a new changeup he learned by watching videos on the internet.

    SCOUTING REPORT: Romero has long looked the part of a major league reliever. His fastball sits 95 mph with sink and touches 98. He pairs it with an 86-88 mph breaking ball that shows late life. He previously struggled to commit to a third pitch, allowing hitters to sit on his heater if command of his breaking ball went awry, but his new changeup could be the answer to those problems and has the look of a potentially plus pitch. Romero's control is firmly below-average and his walk rate has increased successively at each new level.

    THE FUTURE: The A's continue to ask Romero to focus more on the little things like holding runners, but there's no denying the arsenal. He could help the A's bullpen in 2021.

  27. 27. Cody Thomas | OF
    Cody Thomas
    Born: Oct 8, 1994
    Bats: L Throws: R
    Ht.: 6'4" Wt.: 211
    Drafted/Signed: Oklahoma, 2016.

    TRACK RECORD: Thomas was a sought-after quarterback prospect in high school, opting to attend Oklahoma and play both football and baseball. He didn’t spend an overwhelming amount of time on the field in either sport, mostly serving as Baker Mayfield’s backup and playing one full baseball season. But Thomas showed enough to entice the Dodgers in the 13th round of the 2016 draft, signing for an above-slot $297,500 bonus. Oakland acquired him in February alongside Adam Kolarek in a trade with the Dodgers, sending Sheldon Neuse and Gus Varland to Los Angeles.

    SCOUTING REPORT: A lack of reps in college coupled with the lost 2020 season means Thomas is much more raw than a typical 26-year-old. But he has shown immense raw left-handed power, hitting 23 homers for Double-A Tulsa in 2019. There’s length to Thomas’ swing that results in a considerable amount of swing-and-miss. The A’s are impressed with Thomas’ combination of athleticism and physicality and believe he can handle all three outfield positions, although his average speed is more likely suited for a corner spot.

    THE FUTURE: Consistent upper-level at-bats are needed for Thomas, who fits the mold of a powerful, athletic lefty bat the A’s covet.

  28. 28. Lazaro Armenteros | OF
    Lazaro Armenteros
    Born: May 22, 1999
    Bats: R Throws: R
    Ht.: 6'0" Wt.: 182
    Drafted/Signed: Cuba, 2016.
    Signed By: Raul Gomez.

    TRACK RECORD: Armenteros landed the largest bonus of any A's international signing in 2016 at $3 million, but he has yet to translate his enticing tools into production as a professional. He struck out 227 times at high Class A Stockton in 2019, the most strikeouts of any player in the minor leagues, and was not invited to either the alternate training site or instructional league in 2020.

    SCOUTING REPORT: Armenteros has tantalizing plus raw power and speed. The issue is he rarely gets to that plus raw power. Armenteros' swing doesn't stay in the strike zone very long and he has struggled with pitch recognition, especially on breaking balls. He often swings wildly and is an easy out for pitchers who can land a breaking ball in the zone. Armenteros' speed does play when he gets on base and helps him play an average outfield, although he's limited to left field because of a below-average arm.

    THE FUTURE: Armenteros has mostly confounded the A's so far as a professional. He's still just 21 years old and has a combination of tools they don't want to give up on.

  29. 29. Seth Brown | 1B/OF
    Seth Brown
    Born: Jul 13, 1992
    Bats: L Throws: L
    Ht.: 6'1" Wt.: 223
    Drafted/Signed: Lewis-Clark State (Idaho), 2015 (19th round).
    Signed By: Jim Coffman.

    TRACK RECORD: A 19th-round pick out of NAIA Lewis-Clark State, Brown had a Cinderella rise to the majors and hit well in his debut in 2019. He made a brief, seven-game cameo with Oakland in 2020 and spent the rest of the summer at the alternate training site.

    SCOUTING REPORT: Brown re-tooled his swing in search of more launch angle prior to 2017 and unlocked considerable power. It has yet to translate to the big leagues in a very small sample size -- zero homers in 88 at-bats--but his plus raw power is as good as any in the A's system. He makes solid contact and has a chance to be an average hitter against righthanders as part of a platoon. Brown has worked hard to improve his outfield defense in the hopes of enhancing his versatility and giving him more avenues to playing time. He's a fine defender at first base.

    THE FUTURE: The A's continue to look for more lefthanded bats, and some believe the 28-year-old Brown can still carve out a part-time role as a thumper.

  30. 30. Wandisson Charles | RHP
    Wandisson Charles
    Born: Sep 7, 1996
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 263
    Drafted/Signed: Dominican Republic, 2015

    TRACK RECORD: Charles boosted his stock considerably in 2019, striking out 93 batters in 62.1 innings of relief between three levels, topping out at Double-A Midland. He spent 2020 pitching at both Oakland’s alternate training site and fall instructional league, showcasing the best fastball of any pitcher in Oakland’s system.

    SCOUTING REPORT: The hard-throwing righty regularly sat between 96-98 mph and occasionally touched triple-digits at both the alternate site and instructs in 2020. He pairs his imposing fastball with an above-average, late-breaking slider he’s capable of throwing in any count, and also features a work-in-progress changeup. Charles generates plenty of whiffs but also issues a concerning amount of free passes (16% walk rate in 2019). The A’s worked with him in 2020 to reduce the head tilt and stay more on line in his delivery in the hopes it will result in more strikes thrown, especially with his off-speed pitches.

    THE FUTURE: Improved command and a continued refinement of his delivery are keys for Charles in 2021. If he throws more strikes, he could help Oakland’s bullpen by the end of the year.
