Player Reports

  1. 1. Corbin Carroll | OF
    Corbin Carroll
    Born: Aug 21, 2000
    Bats: L Throws: L
    Ht.: 5'10" Wt.: 165
    Drafted/Signed: HS--Seattle, 2019 (1st round).
    Signed By: Dan Ramsay.
    Minors: .435/.552/.913 | 2 HR | 3 SB | 23 AB

    Hitting: 60. Power: 50. Running: 70. Fielding: 60. Arm: 45.

    TRACK RECORD: Carroll was viewed as an advanced high school hitter when the Diamondbacks selected him with the 16th overall pick in 2019 and signed him for $3,745,500 to forgo a UCLA commitment. He lived up to that billing during his pro debut, hitting .299/.409/.481 as he advanced to short-season Hillsboro. Carroll opened even more eyes with his play at the alternate training site in 2020, when he excelled against far more advanced pitchers. He looked so mature in his all-around game that some wondered, albeit prematurely, if he might be the rare fast-to-the-majors high school player.

    SCOUTING REPORT: Carroll is undersized physically at a listed 5-foot-10. That gives him something in common not only with other prospects in Arizona's system but also Mookie Betts, Andrew Benintendi and Jackie Bradley Jr., all of whom were drafted by the Red Sox under Amiel Sawdaye, who now oversees amateur scouting for the D-backs. Carroll is strong, wiry and tremendously athletic. He has a fluid lefthanded swing he uses to spray hard line drives to all fields. His approach is mature beyond his years with an innate understanding of the strike zone, an ability to recognize spin and a knack for swinging at pitches on which he can do damage. Carroll is quick to make adjustments and showed during his time at the alternate training site that pitchers couldn't get him out the same way twice. He has plus-plus speed and gets out of the box quickly, which allows him to beat out his share of infield hits. Carroll's raw power is impressive and he can drive balls with authority in games, but evaluators caution he might be more of a 10-15 home run-type whose speed will help inflate his slugging percentages early in his career before he grows into more power as he matures. He projects as a plus defender in center field and can shift to both corners without issue. His fringe-average arm strength is the only part of his game that leaves something to be desired. Carroll's excellent makeup and determined work ethic create optimism he will make the most of his abilities and reach his full potential.

    THE FUTURE: Carroll has played 42 career professional games and still has much to prove—including that he can maintain his level of play across a full season—but he has fewer areas of his game that need refining than most 20-year-olds. Many D-backs officials see Carroll as the player in their system most likely to become a star, with comparisons ranging from Benintendi to Adam Eaton to Johnny Damon.

  2. 2. Jordan Lawlar | SS
    Jordan Lawlar
    Born: Jul 17, 2002
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 190
    Minors: .400/.500/.600 | 0 HR | 1 SB | 5 AB

    The D-backs drafted a prep shortstop with a long track record of success. Lawlar was the shortstop and three-hole hitter for Dallas Jesuit from his first game as a sophomore to the final game of his senior year. He left an inch taller (6-foot-2) and 25 pounds heavier (195 pounds) than he was when he arrived, but his performance was remarkably consistent. Lawlar hit over .400 all three seasons and was one of the best hitters on the summer showcase circuit in both 2019 and 2020. Because he's coming out of Texas two years after Bobby Witt Jr. (and like Witt he's nearly 19 on draft day), Lawlar draws understandable comparisons. Witt had louder tools almost across the board with the exception of the hit tool, but Lawlar has plenty of plus tools himself, with future 60 speed (he'll turn in 70 times right now) to go with 60 hit, a 60 glove and an above-average arm and future power. Lawlar has a high likelihood of staying at shortstop. Witt (picked No. 2 in 2019) is the only Texas prep shortstop to ever go in the top-10 picks, and Lawlar should be the second. There were concerns when Lawlar showed more swing and miss early in the season, but he resolved that as the season wore on. He struck out in 20% of his plate appearances over the first 21 games of the season. In his final 15 games he struck out once in 55 plate appearances with no degradation in his power production. Lawlar's swing is compact with above-average bat speed. Lawlar is a fast-twitch athlete. Projecting how his power develops separates those who see him as the best prospect in the draft class from those who see him as just a top-tier draft prospect. If his power catches up to his other tools in his 20s, he could be a regular all-star. If not, his hitting ability, speed and defense still would give him a solid path to being an MLB regular with defensive value. The Vanderbilt commit also impresses with his intelligence and maturity.

  3. 3. Alek Thomas | OF
    Alek Thomas
    Born: Apr 28, 2000
    Bats: L Throws: L
    Ht.: 5'11" Wt.: 175
    Drafted/Signed: HS--Chicago, 2018 (2nd round).
    Signed By: Nate Birtwell.
    Minors: .313/.394/.559 | 18 HR | 13 SB | 435 AB

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

    TRACK RECORD: Thomas' father Allen is a former minor league outfielder who has spent the past 17 years as the strength and conditioning coach for the White Sox. The younger Thomas was drafted by the D-backs in the second round in 2018 and hit his way up to high Class A in his first full season. He spent the 2020 season at the alternate training site and held his own against upper-level pitchers.

    SCOUTING REPORT: Thomas packs a punch despite his undersized, 5-foot-11 frame. He has a lot going on in his swing with busy hands, a pronounced leg kick and an aggressive weight transfer, but he manages to get on time. Thomas can generate loud contact that yields extra bases, and he uses his plus speed to take the extra 90 feet. He has a chance to grow into double-digit home run power, but most of his impact will be felt in the form of doubles and triples. He has an aggressive approach but has taken steps to become more selective. In an organization filled with talented defensive outfielders, Thomas is regarded as the best of the group and a potential plus defender in center field, though his arm is a tick below-average.

    THE FUTURE: Thomas is expected to push his way to Double-A to start 2021. His game calls to mind Adam Eaton, Brett Gardner and other smaller, impactful outfielders.

  4. 4. Blake Walston | LHP
    Blake Walston
    Born: Jun 28, 2001
    Bats: L Throws: L
    Ht.: 6'5" Wt.: 195
    Drafted/Signed: HS--Wilmington, N.C., 2019 (1st round).
    Signed By: George Swain.
    Minors: 4-5 | 3.76 ERA | 117 SO | 33 BB | 96 IP

    Fastball: 55. Slider: 60. Changeup: 45. Curveball: 50. Control: 50.

    TRACK RECORD: The D-backs grabbed the projectable, athletic Walston with the second of their two first-round picks in 2019, and they were pleased with the initial returns. Walston added significant weight and strength and spent the 2020 season at the alternate training site, where he performed relatively well.

    SCOUTING REPORT: Walston has a lot of promise, but is still a young pitcher learning to maintain his best stuff. His fastball velocity can reach the mid 90s but is inconsistent, and he's still making mechanical adjustments to get better separation between his average curveball and plus slider. His changeup remains a work in progress. Walston's intensity level fluctuated at the alternate site, leading to speculation that the lack of true competition—of games that counted—was a detriment to his focus. Others wondered if he needed adversity to get the most of his ability. Walston also saw his command and velocity suffer when he got into the middle innings of games. He earned praise for his work and preparation off the field.

    THE FUTURE: Walston missed out on the development that comes from grinding out a full season. He should get the chance to do that in 2021 and will aim to show his best stuff on a more consistent basis.

  5. 5. Bryce Jarvis | RHP
    Bryce Jarvis
    Born: Dec 26, 1997
    Bats: L Throws: R
    Ht.: 6'2" Wt.: 195
    Drafted/Signed: Duke, 2020 (1st round).
    Signed By: George Swain.
    Minors: 2-4 | 4.42 ERA | 89 SO | 30 BB | 76 IP

    Fastball: 55. Slider: 55. Changeup: 55. Curveball: 45. Control: 55.

    TRACK RECORD: Jarvis, the son of longtime major league pitcher Kevin Jarvis, had long been a well-regarded prospect, but his stock jumped in 2020 after he worked at Driveline and Cressey Sports Performance to add velocity and sharpen his secondary pitches. He threw a 15-strikeout perfect game against Cornell in February and became the highest-drafted player in Duke history when the D-backs took him 18th overall.

    SCOUTING REPORT: The D-backs viewed Jarvis as a polished and potentially fast-moving college pitcher after he sat 93-96 mph with plus command of his fastball and a changeup and slider that were both above-average in the spring. He struggled at the alternate training site and instructional league, however, showing subpar fastball command and little deception while serving up a lot of home runs. Jarvis' strong four starts in the abbreviated 2020 college season were better than the rest of his career, so there were already some questions whether it was sustainable. On the positive side, Jarvis earned high marks for his competitiveness and cerebral approach. His changeup also showed plus at its best and he began showcasing a newly-developed curveball..

    THE FUTURE: The early indications suggest Jarvis might not be quite as close to the majors as originally believed. He'll try to rediscover his best form with a full season in 2021.

  6. 6. Slade Cecconi | RHP
    Slade Cecconi
    Born: Jun 24, 1999
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 224
    Drafted/Signed: Miami, 2020 (1st round supplemental).
    Signed By: Eric Cruz.
    Minors: 4-2 | 4.12 ERA | 63 SO | 20 BB | 59 IP

    Fastball: 60. Slider: 60. Changeup: 45. Curveball: 55. Control: 55.

    TRACK RECORD: Cecconi was an intriguing draft prospect as a high school senior, but an injury kept him off the field and steered him to Miami. He posted solid results with the Hurricanes and his stuff, presence and strike-throwing ability enticed the D-backs to draft him 33rd overall as an eligible sophomore. Cecconi quickly validated the selection with dominant showings at the alternate training site and instructional league, drawing reviews as the organization's best pitching prospect.

    SCOUTING REPORT: Working with a prototypical 6-foot-4 pitcher's frame, Cecconi has a methodical, under-control delivery from which he unleashes monster stuff. His fastball sits at 95 mph and touches 98 with impressive life. He backs up his heater with a wipeout slider that is another plus pitch. His curveball is a bit loopy but still gives hitters trouble, serving as a good change of speed. His changeup is a fringy offering that is a clear fourth pitch. Cecconi throws strikes and earns praise for his command, but he does have a history of leaving the ball over the plate too much or falling off as his starts wear on.

    THE FUTURE: Cecconi looked like a polished starter over the summer in 2020 but still has to show he can pitch deep into games and maintain his best stuff over a long season.

  7. 7. Ryne Nelson | RHP
    Ryne Nelson
    Born: Feb 1, 1998
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 190
    Drafted/Signed: Oregon, 2019 (2nd round).
    Signed By: Dan Ramsay.
    Minors: 7-4 | 3.17 ERA | 163 SO | 40 BB | 117 IP

    TRACK RECORD: Nelson shifted his focus to pitching at Oregon in 2019 after spending his first two years as a two-way player. He struggled with command and control and was dropped from the Ducks' rotation to the bullpen, but his power stuff convinced the D-backs to draft him in the second round. He showed up at instructional league in 2020 looking like a different pitcher, giving the D-backs hope he could develop into a starter.

    SCOUTING REPORT: Nelson has a lighting-fast arm that generates fastballs that sit 94-95 mph, touch 98 and have excellent life through the zone. He has two additional weapons in his curveball and slider. His curveball is the better pitch when he throws it hard in the 83 mph range, while his slider generates good sweep despite Nelson's high arm slot. He made big strides with his changeup, but it remains his fourthbest offering. Nelson's control has always been the question mark. The progress he made to average was a bright spot in 2020 for the D-backs, who no longer have to squint to see a future starter.

    THE FUTURE: Nelson will need to continue progressing to stick in the rotation. High Class A is likely his next test.

  8. 8. Geraldo Perdomo | SS
    Geraldo Perdomo
    Born: Oct 22, 1999
    Bats: B Throws: R
    Ht.: 6'3" Wt.: 184
    Drafted/Signed: Dominican Republic, 2016.
    Signed By: Junior Noboa/Elvis Cruz.
    Minors: .238/.357/.359 | 6 HR | 8 SB | 298 AB

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

    TRACK RECORD: After signing for just $70,000 in 2016, Perdomo quickly looked like a bargain with his elite plate discipline and ability to play shortstop. After an impressive U.S. debut in 2018, Perdomo advanced to high Class A in 2019 and took a star turn as a 19-year-old in the Arizona Fall League. The D-backs brought him to their alternate training site in 2020.

    SCOUTING REPORT: Perdomo primarily stands out on defense but has plenty of offensive tools as well. The switch-hitter controls the strike zone, has good bat speed from both sides of the plate and has posted solid results against both lefties and righties. Mostly a singles and doubles hitter, Perdomo said he added 17 pounds of muscle to his athletic frame after the 2019 season and could still add more. Perdomo is a graceful defender who would be a slightly above-average major league shortstop right now and could be a plus defender in the future. He has soft, reliable hands and an above-average arm, while his above-average speed gives him plenty of range. Nearly fluent in English, Perdomo is viewed as a team leader.

    THE FUTURE: Perdomo is set to open 2021 at Double-A. The D-backs have Nick Ahmed signed through 2023, so Perdomo has time to develop his offensive game.

  9. 9. AJ Vukovich | 3B
    AJ Vukovich
    Born: Jul 20, 2001
    Bats: R Throws: R
    Ht.: 6'5" Wt.: 210
    Drafted/Signed: HS--East Troy, Wis., 2020 (4th round).
    Signed By: Nate Birtwell.
    Minors: .272/.320/.446 | 13 HR | 16 SB | 368 AB

    TRACK RECORD: Vukovich was a two-sport star in high school who was a finalist for Wisconsin's Mr. Basketball. The D-backs drafted him in the fourth round in 2020 and signed him for $1.25 million, the equivalent of second-round money, to forgo a Louisville commitment. Vukovich made a loud first impression at instructional league in the fall, impressing the organization with consistent hard contact and a mature routine and work ethic.

    SCOUTING REPORT: Vukovich is lean and lanky and has more athleticism than might be apparent at first glance. Despite his big frame and long levers, his swing is relatively short and direct with few moving parts. With his stance slightly closed, he wears out the right-center field gap. He shows a good approach, a feel for finding the barrel and plus power potential. Defense hasn't been a focus for Vuckovich, but he made strides in his fundamentals at third base during the fall. He still has a long way to go and might end up shifting to an outfield corner. He is a below-average runner.

    THE FUTURE: Vukovich should hit enough for an outfield corner. Some observers believe he could develop into a Nick Castellanos type.

  10. 10. Corbin Martin | RHP
    Corbin Martin
    Born: Dec 28, 1995
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 225
    Drafted/Signed: Texas A&M, 2017 (2nd round).
    Signed By: Noel Gonzales-Luna (Astros).
    Minors: 2-0 | 5.93 ERA | 30 SO | 19 BB | 28 IP

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

    TRACK RECORD: Martin jumped on the fast track after being drafted by the Astros in the second round in 2017 and reached the majors in 2019. That rise was interrupted by Tommy John surgery in July 2019—less than a month before the D-backs acquired him in the Zack Greinke deal. Just as Martin was approaching a return in 2020, he suffered a strained left oblique that effectively ended his season.

    SCOUTING REPORT: Martin returned to the mound in the fall, appearing in intrasquad games and instructional league, and looked mostly like his normal self. His velocity was a tick down, ranging from 92-95 mph, but he also was not throwing at full intensity. Before surgery, Martin had a solid four-pitch mix, with his fastball complemented by a slider, curveball and changeup that all graded average to above. He's since tinkered with a new grip on his curveball and received good feedback on it, helping solidify it as a potentially above-average pitch. He's previously shown above-average control when healthy.

    THE FUTURE: Martin will enter spring training as one of the club's depth starter options. He's previously shown No. 3 or 4 starter potential but has to stay healthy and show his stuff comes all the way back.

  11. 11. Kristian Robinson | OF
    Kristian Robinson
    Born: Dec 11, 2000
    Bats: R Throws: R
    Ht.: 6'3" Wt.: 215
    Drafted/Signed: Bahamas, 2017.
    Signed By: Cesar Geronimo/Craig Shipley.

    Hitting: 45. Power: 70. Running: 60. Fielding: 55. Arm: 50.

    TRACK RECORD: Robinson signed for $2.5 million in 2017 and quickly impressed the organization with his maturity, mindset and athleticism. He put together a strong season in the short-season Northwest League before a promotion to the low Class A Midwest League at age 18 in 2019, and he showed up to spring training in 2020 with a slimmed-down physique after experimenting with a paleo diet in the offseason. Robinson joined the alternate training site in August and finished the year in instructional league.

    SCOUTING REPORT: Robinson's natural athleticism, gargantuan raw power and plus speed give him the building blocks for massive upside. He does things few players can, including hitting a home run into the Chase Field pool area in three consecutive at-bats during alternate site play. But while his power and speed are undeniable, concerns about how often he swings and misses are starting to raise questions about his ability to reach his ceiling. He projects as a fringe-average hitter who strikes out often, though he's still young and has relatively little experience against quality pitching coming from the Bahamas. He is a potential above-average defender in an outfield corner.

    THE FUTURE: Robinson was hurt by a lack of reps in 2020. He'll look to make up for lost time in 2021.

  12. 12. Adrian Del Castillo | C
    Adrian Del Castillo
    Born: Sep 27, 1999
    Bats: L Throws: R
    Ht.: 5'0" Wt.: 208
    Minors: .265/.367/.422 | 1 HR | 0 SB | 83 AB

    In a draft class light on college bats, Del Castillo entered the year as the clear-cut, top college hitter in the class, with a track record of hitting that dates back to his time as a high schooler with Gulliver Prep in Miami when he was a top-200 prospect in the 2018 class. After hitting .336/.430/.571 over his first two seasons with Miami, Del Castillo took a step back in his draft-eligible third year this spring, hitting .284/.388/.411 through 51 games with more strikeouts (28) than walks (25) for the first time in his career, and just three home runs. That lack of over-the-fence power is concerning for teams who are skeptical about Del Castillo sticking behind the plate at the next level. He would have to play a corner if he can't catch, which will put more pressure on his bat and his power production. Each of his three home runs this spring were to right field, and historically in his better home run seasons, Del Castillo has mostly used the pull side. He did homer five times in 37 games in the Cape Cod League in 2019, but that power production with a wood bat also came with an uncharacteristic 32-to-9 strikeout-to-walk rate. This spring he did most of his damage on fastballs and struggled to regularly impact breaking stuff, though that wasn't much of an issue for him in previous years. Del Castillo does have a loose, easy swing from the left side, with solid zone recognition and low strikeout rates for his career, so many scouts still think he'll be a plus hitter, but the question of defensive profile and impact potential loom after his 2021 season. Del Castillo put in plenty of work over the summer with Royals catcher Salvador Perez, where he worked on improving his arm strength, blocking and receiving but he still needs work in those areas—particularly the latter two.

  13. 13. Luis Frias | RHP
    Luis Frias
    Born: May 23, 1998
    Bats: R Throws: R
    Ht.: 6'3" Wt.: 235
    Drafted/Signed: Dominican Republic, 2015.
    Signed By: Jose Ortiz/Junior Noboa.
    Minors: 9-7 | 4.93 ERA | 126 SO | 45 BB | 112 IP

    TRACK RECORD: Frias is a big-bodied power pitcher the D-backs signed for $50,000 in 2015. He reached the low Class A Midwest League in 2019 and spent 2020 at the alternate training site, where he was occasionally hit hard by more advanced hitters.

    SCOUTING REPORT: Frias has the building blocks to be a starting pitcher. His fastball sits in the mid-toupper 90s and his spike curveball serves as his out pitch. He added a splitter in 2019 and began throwing a slider in 2020, something he hopes to use as a called-strike pitch. As with other power arms in the system, his command remains a work in progress. There was some sense among the organization that his occasional struggles at the alternate site, much of which stemmed from pitches that caught too much of the plate, could help drive home the importance of improved command.

    THE FUTURE: Frias' profile remains relatively unchanged from previous years. If he can make strides with the consistency of his command and his secondary stuff, he could become an innings-eating mid-rotation starter. Otherwise, he fits best in relief.

  14. 14. Brandon Pfaadt | RHP
    Brandon Pfaadt
    Born: Oct 15, 1998
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 230
    Drafted/Signed: Bellarmine (Ky.), 2020 (5th round).
    Signed By: Jeremy Kehrt.
    Minors: 8-7 | 3.21 ERA | 160 SO | 28 BB | 132 IP

    TRACK RECORD: Pfaadt became just the ninth player to be drafted out of Division II Bellarmine in Louisville and the highest since Todd Wellemeyer was a fourth-rounder in 2000. Pfaadt is one of four family members to play baseball there; grandfather Bob and older brother Brady preceded him, while his younger brother Brett will be a sophomore this year.

    SCOUTING REPORT: Pfaadt uses an old-school delivery, bringing his hands up over his head, then drives down the mound with a strong, prototypical starter's frame. His fastball sat 94-95 mph in instructional league with a power changeup in the upper 80s and a pair of breaking pitches that blend together and/or pop out of his hand. He throws strikes, but his command could stand to improve. Pfaadt's velocity tended to dip in the middle innings in college, so he will have to prove he can maintain stuff deep into games.

    THE FUTURE: Pfaadt is working to incorporate his lower half more in his delivery and needs to make his curveball and slider two distinct pitches, but he has a lot of starter attributes. He will likely open 2021 at one of the organization's Class A affiliates.

  15. 15. Conor Grammes | RHP
    Conor Grammes
    Born: Jul 13, 1997
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 205
    Drafted/Signed: Xavier, 2019 (5th round).
    Signed By: Jeremy Kehrt.
    Minors: 0-2 | 7.46 ERA | 32 SO | 12 BB | 26 IP

    TRACK RECORD: Grammes was a two-way player who spent more time as a position player than a pitcher at Xavier. Intrigued by his quick arm and athleticism, the D-backs drafted Grammes as a pitcher in the fifth round in 2019 despite his limited experience on the mound. The early returns, albeit not in a normal minor league setting, were encouraging in 2020.

    SCOUTING REPORT: Grammes has some of the best pure stuff in the D-backs' organization. His fastball routinely sat 97-100 mph during instructional league and he backed it up with a hard, 87-88 mph slider and mid-80s power curveball that both drew above-average grades. Grammes also has a firm, upper-80s changeup, but it lags behind his two breaking balls. Grammes walked more than six batters per nine innings in college. His control has made strides, but his command remains a work in progress. With the cancellation of the 2020 minor league season, he has not had the opportunity to show he can go deep into games or maintain his stuff over a full season.

    THE FUTURE: Grammes is most likely a future hard-throwing reliever. Given how much he has improved since being drafted and his relative lack of pitching experience, starting isn't out of the question if he keeps making strides.

  16. 16. Tommy Henry | LHP
    Tommy Henry
    Born: Jul 29, 1997
    Bats: L Throws: L
    Ht.: 6'3" Wt.: 205
    Drafted/Signed: Michigan, 2019 (2nd round supplemental).
    Signed By: Jeremy Kehrt.
    Minors: 4-6 | 5.21 ERA | 135 SO | 53 BB | 116 IP

    TRACK RECORD: Henry had a dominant run in the College World Series in 2019, shortly after the D-backs made him the highest-drafted Michigan pitcher in 25 years. The club liked his pitch mix and his athleticism, hoping it would translate into further development. Though the 2020 minor league season was cut short by the pandemic, Henry's early returns were encouraging at the alternate training site.

    SCOUTING REPORT: Henry's fluctuations in velocity were a concern leading up to the draft, but his fastball ticked up and stayed there during his time at the alternate site, sitting at 93 mph and topping out at 95. He credited the uptick to a better incorporation of his lower half along with long-tossing and work with weighted balls. Henry's above-average slider is generally viewed as his primary secondary offering, but his average changeup made strides to the point that Henry has called it his favorite pitch. He also picked up a curveball this year that has promise. Henry's best asset is his plus control.

    THE FUTURE: Henry's ceiling would be higher if he could find a dominant, go-to secondary pitch. Until then, he projects as a back-end starter.

  17. 17. Seth Beer | 1B/DH
    Seth Beer
    Born: Sep 18, 1996
    Bats: L Throws: R
    Ht.: 6'3" Wt.: 225
    Drafted/Signed: Clemson, 2018 (1st round).
    Signed By: Gavin Dickey (Astros).
    Minors: .287/.398/.511 | 16 HR | 0 SB | 362 AB

    TRACK RECORD: Beer put up gaudy numbers at Clemson to become the first freshman to win the Dick Howser Trophy in 2016. The Astros drafted him 28th overall in 2018 and sent him to the D-backs in the Zack Greinke trade a year later. After hitting .289/.389/.516 and reaching Double-A in his first full season, Beer spent 2020 at the D-backs' alternate site and was arguably their best hitter there.

    SCOUTING REPORT: Beer isn't just a bat-first player --he appears to be bat only. He has a mature approach, a smooth, strong swing and above-average raw power. He's hit for average and power at every level and projects to continue to do so. Despite the work he has put in to improve defensively, he hasn't made much progress. His footwork at first base is not good, nor are his hands. He is worse in the outfield based on near bottom-of-the-scale speed. Even if he could be a poor-yet-passable defender, it likely would not be good enough for the D-backs, who put a premium on defense.

    THE FUTURE: If the universal DH is here to stay, that gives Beer a possible path with the D-backs. Even then, they value flexibility, which Beer does not provide. He can hit, but his future likely lies in a different organization.

    Minors: .294/.399/.615 | 20 HR | 1 SB | 296 AB

    A second-round pick in 2017, Ellis got into better shape this year, played a better third base and hit consistently at Triple-A Reno.

    Bats: R Throws: R
    Ht.: 6'0" Wt.: 165
    Drafted/Signed: Ball State, 2019 (1st round supplemental).
    Signed By: Jeremy Kehrt.
    Minors: 5-6 | 3.98 ERA | 145 SO | 36 BB | 111 IP

    TRACK RECORD: Jameson is undersized and the product of humble roots. He was raised by a single mom who worked two jobs, an upbringing that helped shape his competitive nature. He was initially a two-way player at Ball State but ultimately developed into the program's ace and best pitching prospect since Bryan Bullington was the No. 1 overall pick in the 2002 draft. The D-backs took Jameson with the 34th overall pick in 2019 and signed him for $1.4 million.

    SCOUTING REPORT: Despite his small frame, Jameson generates some of the best velocity in the organization. He pumps fastballs that sit in the mid 90s as a starter and 98-100 mph in relief with his super-quick arm speed. But Jameson does so with significant effort, taking away his ability to command it. His fastball also gets hit more than would be expected, raising questions about a potential lack of deception. Jameson has a full repertoire, including a slider, curveball and changeup that all have average potential, though his breaking pitches are inconsistent and sometimes blend together.

    THE FUTURE: Jameson may need to tone down his delivery in order to gain consistency with his location and the shape of his secondary stuff. In the eyes of many, he is looking more and more like a future late-inning reliever.

    Signed By: Dennis Sheehan.
    Minors: 6-11 | 5.87 ERA | 96 SO | 39 BB | 108 IP

    Getting more consistency in his delivery this year was the key for Arizona's 2017 third-round pick as he showed better overall command of his arsenal, and he moved up to Double-A Amarillo after four outings at High-A Hillsboro. It's a command profile with an above-average or better changeup being his best pitch.

    Levi Kelly
    Born: May 14, 1999
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 205
    Drafted/Signed: HS--Bradenton, Fla., 2018 (8th round).
    Signed By: Luke Wrenn.
    Minors: 2-0 | 5.40 ERA | 27 SO | 28 BB | 25 IP

    TRACK RECORD: The D-backs took a flier on the projectable Kelly in the eighth round in 2018. He rewarded them with a dominant season in the low Class A Midwest League in his first full season and continued to impress in 2020. Kelly opened eyes at summer camp and continued to pitch well at the alternate training site before tiring at the end of the year.

    SCOUTING REPORT: Kelly's fastball sits 94-96 mph and touches 98, but his best weapon is a wipeout slider that was nearly unhittable for much of the summer at the alternate site. He also throws a splitter that serves as a change of pace offering and added a curveball, giving him the potential for a well-rounded starter's arsenal. Kelly's fastball command comes and goes, and some observers would like to see him dial back the intensity in his high-effort delivery, which leads to fringy control. He is highly competitive and has a great work ethic.

    THE FUTURE: Kelly needs to tighten up his command and third pitch to remain in the rotation. The D-backs know if starting doesn't work out, he would fit nicely in the back of a bullpen.

    Born: Jul 30, 1997
    Bats: L Throws: L
    Ht.: 6'3" Wt.: 215
    Drafted/Signed: Virginia, 2018 (1st round supplemental).
    Signed By: Rick Matsko.
    Minors: .253/.332/.500 | 15 HR | 29 SB | 328 AB

    TRACK RECORD: McCarthy received a $1.65 million bonus as the 39th overall pick in 2018, following his older brother Joe on a path from Virginia to the professional ranks. He immediately went about working to rebuild his swing, an effort that was sidetracked by injuries that limited him to just 53 games with high Class A Visalia in 2019.

    SCOUTING REPORT: McCarthy showed up to instructional league in 2020 looking completely different. He put on some 20 pounds of good weight, and just as noticeable were the changes to his swing. Once rigid and upper-body driven, it is now more athletic while incorporating a leg kick. McCarthy was perhaps the D-backs' most productive hitter during the fall, a performance that teased flashes of an aboveaverage hitter with 20-plus home run power and re-established his prospect value. McCarthy remains an excellent defender whose speed plays well in center field. He saw time at first base during instructs, a move designed to increase his versatility.

    THE FUTURE: McCarthy's transformation brings to mind the swing changes made by former D-backs outfielder Mitch Haniger. He'll now try to show he can carry that success into 2021 and sustain it.

  23. 23. Wilderd Patino | OF
    Wilderd Patino
    Born: Jul 18, 2001
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 175
    Drafted/Signed: Venezuela, 2017.
    Signed By: Cesar Geronimo/Kristians Pereira.
    Minors: .218/.286/.306 | 2 HR | 6 SB | 147 AB

    TRACK RECORD: Patiño needed surgery on the growth plate in his right elbow in the spring of 2017, prompting the Rangers to back out of a $1.3 million agreement. The D-backs swooped in and signed him for $985,000, then had Patiño undergo revision surgery. He returned the following summer and broke out in 2019, when he hit .349/.403/.472 in the Rookie-level Arizona League and earned a late promotion.

    SCOUTING REPORT: Patiño has the raw materials to be an impact major leaguer. His strong, physical frame can produce above-average power to all fields and he has plus speed and athleticism in the outfield. His game remains raw, however. He has made adjustments at the plate, including the way he grips the bat, but could stand to make more. He primarily needs to tone down his aggressiveness, which works against him and will get further exploited against advanced pitchers. Patiño is not as sharp a defender as others in the system and may be forced to a corner. His fringe-average arm may limit him to left field.

    THE FUTURE: Patiño was among those most hurt by the lack of a minor league season, given how much development is still needed. He should open 2021 at low Class A.

    Alberto Ciprian
    Born: Nov 5, 2002
    Bats: R Throws: R
    Ht.: 5'0" Wt.: 160

    Ciprian signed with the Brewers for $500,000 during the 2019-20 international signing period on the strength of his above-average raw power and explosive hand speed. The D-Backs acquired him from Milwaukee for Eduardo Escobar. His power is ahead of his hitting ability and he's a bit of a lottery ticket with very little pro experience. His projectable body and power give him some upside and he has a chance to stick at third base with his improving footwork and above-average arm.

  25. 25. Manuel Pena | SS
    Manuel Pena
    Born: Dec 5, 2003
    Bats: R Throws: R
    Ht.: 6'0" Wt.: 170

    TRACK RECORD: Peña built a reputation as one of the top pure hitters from the Dominican Republic in his international class when he signed with the D-backs during the 2020-21 signing period.
    SCOUTING REPORT: Peña takes a compact swing with a good bat path from the left side and an advanced offensive approach. That has helped him hit well in games with the ability to barrel balls consistently. Peña makes hard contact for his age, has a swing geared to hit the ball in the air and the physical projection to develop 20-25 home run power in the future, possibly more given his knack for putting the sweet spot on the ball. Peña is an offensive-oriented player who many scouts thought would go to third or second base. Long term, that is probably still the case, but he has improved defensively in terms of his ability to read hops and use better technique to field the ball with good balance and body control, giving him a chance to keep developing as a shortstop. A slightly below-average runner, Peña has soft hands but needs to improve his footwork. He's a slightly below-average runner whose range probably leads him off the position as he gets bigger, with a 50-55 arm that could be plus in the future.
    THE FUTURE: Peña is one of the more advanced hitters the D-backs have signed out of the Dominican Republic in recent years. He's still several years away, but his hitting ability should translate quickly.

  26. 26. Ryan Weiss | RHP

    Ht.: 6'4" Wt.: 210

    Signed By: Jeremy Kehrt.
    Minors: 6-3 | 4.60 ERA | 88 SO | 31 BB | 79 IP

    Not ranked highly on prospect lists since being selected from Wright State in the fourth round in 2018, Weiss refined his delivery by getting more separation with his hips and shoulder and was moved to the bullpen during the season. It's a role that better suits his arsenal, with a fastball at 95-97 mph and a plus breaking ball.

  27. 27. Stuart Fairchild | OF
    Stuart Fairchild
    Born: Mar 17, 1996
    Bats: R Throws: R
    Ht.: 6'0" Wt.: 190
    Drafted/Signed: Wake Forest, 2017 (2nd round).
    Signed By: Perry Smith (Reds).
    Minors: .296/.383/.562 | 9 HR | 7 SB | 162 AB

    A prototypical extra outfielder, Fairchild was acquired from Cincinnati in the Archie Bradley trade at the 2020 trade deadline and recently made his MLB debut. A plus defender, Fairchild has the speed to handle all three outfield positions.

  28. 28. Jose Fernandez | SS
    Jose Fernandez
    Born: Sep 22, 2003
    Bats: R Throws: R
    Ht.: 6'0" Wt.: 165
    Minors: .250/.320/.304 | 0 HR | 4 SB | 112 AB

    TRACK RECORD: Dominican shortstop Manuel Peña and Venezuelan shortstop Jefferson Peña were more prominent prospects among the D-backs 2020-21 international signings. Fernandez, though, has trended up significantly and could end up one of the best values of his international class.
    SCOUTING REPORT: Fernandez has a lean, ultra-projectable frame at 6-foot-3, 165 pounds, with an exciting mix of skills on both sides of the ball, tools and the strength projection left for those tools to continue trending up. He has hit well in games with a good swing and a high contact rate. It's gap power now but he hits the ball hard with backspin to all fields and the strength projection to grow into above-average power once he packs on size. Fernandez is athletic with slightly above-average speed and is a fluid mover at shortstop. He has good actions and fields the ball with sweet hands and an arm that's flashing plus and could get even stronger with physical maturity. If he outgrows the position, he could go to third base, but he has the ability to stick at shortstop as long as he maintains his agility and athleticism.
    THE FUTURE: Fernandez still has a lot to prove, but he's an arrow-up player with breakout potential.

  29. 29. Juan Corniel | SS
    Juan Corniel
    Born: Oct 2, 2002
    Bats: B Throws: R
    Ht.: 5'0" Wt.: 150
    Minors: .245/.285/.324 | 0 HR | 6 SB | 188 AB

    Corniel is one of a trio of promising shortstop prospects at the lower levels. He's a high-waisted athlete with a chance to be a special defender in the middle infield, but with holes in his swing there's plenty of development at the plate ahead of him.

  30. 30. Ryan Bliss | 2B
    Ryan Bliss
    Born: Dec 13, 1999
    Bats: R Throws: R
    Ht.: 5'0" Wt.: 165
    Minors: .267/.326/.448 | 6 HR | 13 SB | 165 AB

    An undersized, 5-foot-9, 165-pound middle infielder, Bliss stood out as a high schooler for his fantastic hands, footwork and bat-to-ball skills. Teams opted to let him get to school in part because of concerns with his offensive upside, but he was the sole Auburn player to start every game in 2019 and managed a .281/.367/.369 batting line to go with 11 doubles and 11 stolen bases. Bliss was off to an even better start in 2020, hitting .377/.412/.597 with more extra-base pop and as many walks (five) as strikeouts (five). After playing second base as a freshman, Bliss shifted to shortstop, and he certainly has the athleticism, hands and actions for the position, but fringy arm strength could make him a better fit for second base at the next level—where he's still adept at turning the double play. Bliss has solid bat-to-ball skills and doesn't strike out often—around 13% for his career—with bat speed and an approach that was best described as contact-oriented before he hit a career-best 15 home runs this spring through 50 games. All of those home runs went to left field and scouts still think he'll be a below-average power hitter with wood, but for teams who want to buy into his power output this season, his combination of 15 or more homers and a 12-13% strikeout rate puts him in company that includes hitters like Henry Davis, Connor Norby and Colton Cowser—none of whom put up their numbers in the SEC.
