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

    BA Grade: 60/High

    Track Record: Carroll emerged early as one of the most talented players in the 2019 draft class, but concerns about his small stature caused him to fall to the 16th overall pick, where the D-backs were thrilled to scoop him up. He signed for $3.75 million to forgo a UCLA commitment and quickly went about justifying the D-backs’ excitement. Carroll performed well in his pro debut and excelled at the alternate training site in 2020. He was off to a fast start at High-A Hillsboro in 2021 when he hurt himself on a home-run swing, tearing his labrum and capsule in his right, non-throwing shoulder. After having season-ending surgery in mid-May, Carroll tried to make the most of his downtime by taking college classes and attending D-backs games at Chase Field, where he sat behind the plate with the team’s advance scout, Jeff Gardner, asking questions and talking baseball.

    Scouting Report: Carroll is a dynamic, multi-talented player who projects to fit at or near the top of a major league lineup. He has a fluid lefthanded swing, an all-fields approach and a propensity for finding the barrel, all of which helps him project to be a plus hitter. He produces impressive slugging numbers despite his 5-foot-10, 165-pound stature by shooting balls into the gaps and down the lines for extra bases. He has a sort of effortless swing in which he simplifies his movements to generate high exit velocities with ease. He is able to add loft while avoiding too steep of an angle in his swing, resulting in consistent hard contact in the air without a corresponding increase in swings and misses at a level rarely seen for a player his age. Beyond his physical skills, Carroll has a mature approach and an advanced feel for the game. He makes quick adjustments at the plate and is sound fundamentally in the outfield and on the bases. He covers wide swaths of ground with his plus-plus speed and projects to be plus defensive center fielder. If he ends up in a corner, he would profile better in left field, where his fringe-average arm would best fit. How Carroll’s tools play after his injury remains a question. Not only did surgery cost him a year of development, but the procedure was anything but minor, meaning he will have to prove he can get back to being the impact player he was. He has shown upside in limited action but has just 215 career plate appearances in parts of three seasons.

    The Future: The D-backs still view Carroll as a special talent. Before the injury, he drew comparisons to the likes of Johnny Damon and Jacoby Ellsbury. He hopes to be fully healthy for the start of the 2022 season and is aiming to show he can be that type of potential all-star again.

    Scouting Grades: Hit: 60. Power: 55. Speed: 70. Fielding: 60. Arm: 45.

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

    BA Grade: 65/Extreme

    Track Record: An accomplished prep player, Lawlar stood out on the showcase circuit as arguably the top player in the 2021 draft class and was named Gatorade’s Texas player of the year in the spring. The D-backs eagerly selected him with the sixth overall pick and signed him for an above-slot $6.7 million to buy him out of a Vanderbilt commitment. Lawlar made his pro debut in the Arizona Complex League after signing, but he appeared in only two games before he suffered a labrum tear in his left shoulder that required season-ending surgery.

    Scouting Report: Before his injury, Lawlar stood out as a tooled-up prospect with the potential to hit in the middle of the lineup and stick at one of the game’s most demanding positions. He has terrific bat speed that allows him to handle velocity, controls the strike zone and battles through at-bats. He swings and misses a bit too much at times, but he generally self-corrects. Lawlar has plus raw power that occasionally shows up in games and could improve as he matures and adds strength to his athletic frame. For now, his power more safely projects in the form of doubles and triples given his easy plus speed. Defensively, Lawlar is a sure-fire shortstop with good hands, range and footwork. He has a nearly plus-plus, accurate arm and the ability to make difficult plays look easy.

    The Future: Lawlar is expected to be fully healthy by the start of the 2022 season. He might have the most upside of any player in the D-backs organization and draws comparisons to a young Carlos Correa.

    Scouting Grades: Hit: 60. Power: 55. Speed: 60. Fielding: 60. Arm: 65.

  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

    BA Grade: 55/Medium

    Track Record: Thomas is the son of White Sox strength coach Allen Thomas and grew up around the game, spending time at Guaranteed Rate Field shagging fly balls and picking the brains of big leaguers. The D-backs drafted Thomas in the second round in 2018 and signed him away from a Texas Christian commitment for $1.2 million. Thomas has rocketed through the system since and climbed from Double-A to Triple-A in 2021 while amassing eye-popping numbers. He set new career highs in doubles (29), home runs (18), RBIs (59) and OPS (.953), all in his age-21 season at the minors’ highest levels.

    Scouting Report: Thomas’ career .312/.388/.495 batting line supports the notion of him being a pure hitter. He has quick, strong hands and that allow him to manipulate the barrel. He isn’t physically imposing but he regularly hits balls hard. Though the D-backs say he has tightened up his approach, Thomas remains an aggressive hitter who is looking to swing the bat and do damage. That said, he also owns a solid 10 percent walk rate in his career. Thomas’ swing has a lot of moving parts, including a pronounced leg kick. Defensively, Thomas uses his plus speed to cover wide swaths of ground in center field and gets good reads off the bat to project as a plus defender. His fringe-average arm is somewhat limiting but is fine in center.

    The Future: Thomas is expected to come to big league camp pushing for a spot on the Opening Day roster. Whether it’s right away or not, he figures to impact the big league team at some point early in 2022.

    Scouting Grades: Hit: 60. Power: 45. Speed: 60. Fielding: 60. Arm: 45.

  4. 4. 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

    BA Grade: 55/Medium

    Track Record: Signed for $70,000 in 2016 out of the Dominican Republic, Perdomo raced up the minors and was brought up for his major league debut early in the 2021 season with Nick Ahmed battling knee problems, Perdomo struggled in limited duty and carried those struggles with him when he was sent back to Double-A, prompting the D-backs to to place him on the development list and send him back to Arizona to rebuild his swing and regain his confidence at midseason. It appeared to work as Perdomo hit .329/.415/.527 across three levels after he returned, including a strong showing in the majors in late September.

    Scouting Report: Perdomo is a no-doubt shortstop, with easy, rhythmic movements, good hands and an above-average, dependable arm. He is tougher to evaluate at the plate, particularly after his night-and-day season. He has a discerning eye and the ability to put the bat on the ball, but he has long made soft contact and shown limited ability to drive the ball. After his development list stint, his mentality changed at the plate to where he appeared intent on not just making contact but crushing balls. Whether he can maintain those adjustments will determine whether he reaches his potential as an average hitter with fringy power.

    The Future: Perdomo provides an intriguing alternative to Ahmed, even if his production is heavily weighted toward on-base ability. If Perdomo can slug like he showed late in 2021, he may force his way into the lineup.

    Scouting Grades: Hit: 50. Power: 45. Speed: 55. Fielding: 60. Arm: 55.

  5. 5. 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

    BA Grade: 55/High

    Track Record: The D-backs selected Walston, a former high school quarterback in addition to ace lefthander, with the second of their two first-round picks in 2019 and signed him away from a North Carolina State commitment for $2.45 million. After the coronavirus pandemic delayed his first full season, Walston turned in a solid 2021 across both Class A levels, showing glimpses of the frontline starter the Diamondbacks hope he becomes while also exposing some areas that still need refinement.

    Scouting Report: Walston has nearly everything scouts look for in a frontline starter, including command, velocity, ability to spin the ball and feel to pitch. He still has a thin frame, giving him room for more physical maturity but also affecting his present ability to hold his velocity. At his best, Walston sits in the low-90s and touches 94-95 mph. But his velocity tends to decrease as games wear on, and his average velocity dropped from close to 92 mph in June to a tick under 90 mph in September. Walston’s potentially plus curveball is his most advanced secondary pitch but remains inconsistent. His slider and changeup have improved to be above-average and average, respectively, and he is gaining trust in his changeup in particular. Walston throws everything for strikes with above-average control. He still has maturing to do when it comes to the consistency of his between-starts routine.

    The Future: Walston has the most upside of any starter in the system. He took strides with his preparation, and coaches are excited to see what happens as his improved work ethic translates into further development.

    Scouting Grades: Fastball: 55. Curveball: 60. Slider: 55. Changeup: 50. Control: 55.

  6. 6. 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

    BA Grade: 55/High

    Track Record: After years as a two-way player, Nelson began focusing solely on pitching at Oregon in 2019. The D-backs liked what they saw and selected him with the 56th overall pick after that season. Nelson was more projection than performance when he was drafted, but he showed up at instructional league in 2020 looking more refined and continued that progression through a breakout 2021 season. He went 7-4, 3.17 in 22 starts as he rose from High-A to Double-A and finished tied for third in the minors with 164 strikeouts.

    Scouting Report: Nelson has a slow, methodical delivery, then overwhelms hitters with a fastball that averages 94 mph with high spin rates. He produces rise and carry on his fastball and learned to better locate the pitch up in the zone last year. He also cleaned up his delivery, getting himself more on line and making it more repeatable. Nelson’s average curveball and slider alternate as his best secondary offering, but his curveball might pair best with his fastball. After years of tinkering, he found a changeup grip he likes—he calls it a hybrid circle change—and the pitch took significant strides to become fringy. After years of below-average control, Nelson finally started throwing strikes consistently in 2021, the biggest difference-maker in his season.

    The Future: Given Nelson’s relative newness to pitching, he could still have significant growth ahead of him. His control improvements have started to quiet concerns about a future move to the bullpen, with more observers now envisioning a potential mid-rotation starter.

    Scouting Grades: Fastball: 70. Curveball: 50. Slider: 50. Changeup: 45. Control: 50.

  7. 7. Drey Jameson | RHP
    Drey Jameson
    Born: Aug 17, 1997
    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

    BA Grade: 55/High

    Track Record: The D-backs placed a bet on the undersized Jameson’s athleticism when they selected him with the 34th overall pick in 2019 out of Ball State. Already, the gamble looks like it may pay off. Jameson turned in a solid first full season as a pro in 2021, posting a 3.98 ERA with 145 strikeouts in 110.2 innings as he rose from High-A to Double-A. Most importantly, he also provided reasons to believe he could stick as a starter in the majors.

    Scouting Report: Jameson has perhaps the most electric stuff in the D-backs’ system. His four-seam fastball averages 96 mph, occasionally touching 98-100, and he holds it deep into games and throughout the season. His four-seamer pairs well with a two-seamer that sits in the 91-93 mph range and his slider, which he can throw both for strikes and chase swings, is a dominant pitch that earns plus-plus grades at its best. Jameson’s curveball rates as at least an average offering, as does his changeup, which behaves like a splitter when it’s on. He has eased some durability concerns by toning down his delivery and looks more like a pitcher than a pure thrower, although his 6-foot, 165-pound size remains a question. Hitters at times see the ball well against him and his fastball doesn’t play quite as well as his velocity would suggest.

    The Future: Given his size, Jameson is the sort of prospect who can’t dispel reliever risk until he succeeds as a starter in the majors. He will come to big league camp in 2022 and has a chance to break into the majors during the season.

    Scouting Grades: Fastball: 60. Slider: 70. Curveball: 55. Changeup: 55. Control: 50.

  8. 8. Deyvison De Los Santos | 3B
    Deyvison De Los Santos
    Born: Jun 21, 2003
    Bats: R Throws: R
    Ht.: 6'0" Wt.: 185
    Signed By: Cesar Geronimo/Wil Tejada.
    Minors: .295/.370/.489 | 8 HR | 3 SB | 227 AB

    BA Grade: 55/Very High

    Track Record: De Los Santos is a hulking prospect whose ability to impact the baseball has been his calling card since he signed out of the Dominican Republic for $200,000 in 2019. The D-backs pushed De Los Santos aggressively in 2021 and watched him post strong numbers in his pro debut in the Arizona Complex League before more than holding his own after a late promotion to Low-A Visalia.

    Scouting Report: De Los Santos possesses proverbial “light-tower power” and crushes balls to all fields with apparent ease. There is, and probably always will be, a good bit of swing-and-miss to his game, but the power he is capable of producing projects to be worth the tradeoff. De Los Santos logged a solid 10 percent walk rate but his approach remains unrefined. He puts up impressive batted-ball data but needs to learn to hit fewer balls on the ground. De Los Santos might eventually shift across the diamond to first base. For now, there is some optimism he could stick at third, where he showed improved footwork and reads on balls off the bat. He has enough arm strength for the hot corner, but his throwing accuracy needs to improve.

    The Future: For someone getting his first taste of pro ball, De Los Santos did not disappoint. He fits the profile of a middle-of-the-lineup run producer and figures to open the 2022 season back in Low-A.

    Scouting Grades: Hit: 50. Power: 70. Speed: 40. Fielding: 40. Arm: 50.

  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

    BA Grade: 55/Very High

    Track Record: A multisport athlete in high school, Vukovich signed with the D-backs for an above-slot $1.25 million as a fourth-round pick in 2020 rather than stick with his commitment to Louisville. After a strong showing at instructional league in 2020, he skipped over the complex levels and went straight to Low-A Visalia for his pro debut in 2021. Vukovich got off to a rough start on both sides of the ball but righted the ship, earning a promotion to High-A and finishing with a solid .272/.323/.446 line.

    Scouting Report: Vukovich has a long-levered, athletic frame. He has a closed off stance at the plate, an unusual setup for a modern hitter, but he manages to hit balls hard to all fields and has one of the better better-batted ball profiles of anyone in the D-backs system. Vuckovich’s pure contact skills are good and he has above-average power potential, but his plate discipline needs work. His chase rate spiked when he got to High-A, and he struggles with offspeed and breaking stuff in particular. Defensively, Vukovich showed below-average hands and throwing accuracy at third base during the opening weeks of the season but improved as the year progressed. He still widely projects to move to a corner outfield spot, where he should cover plenty of ground with his average speed.

    The Future: Vukovich draws mixed reviews from rival scouts, but the D-backs are more bullish. They expect his swing decisions will improve and believe he’ll become a middle-of-the-order power hitter with the ability to steal 10-15 bases. Even if he has to move positions, that is enough profile in an outfield corner.

    Scouting Grades: Hit: 50. Power: 55. Speed: 50. Fielding: 40. Arm: 50.

  10. 10. 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

    BA Grade: 50/High

    Track Record: After splitting time between starting and relieving at Division II Bellarmine (Ky.), Pfaadt had a solid showing in the Cape Cod League after his sophomore season and hasn’t looked back. He posted impressive numbers in five starts in his pandemic-shortened junior year, leading the D-backs to draft him in the fifth round, and he zipped up three levels to Double-A in his first season as a pro in 2021. He logged a 3.21 ERA across 22 starts and finished seventh in the minors with 160 strikeouts.

    Scouting Report: Pfaadt is big and physical with a 6-foot-4, 230-pound frame built for logging innings and relentlessly pounds the strike zone with a four-pitch mix. His fastball sits comfortably in the 93-94 mph range, touches 97, and plays up with high spin rates and his aggressiveness using it. It sometimes display good rise and other times good cutting action. His above-average slider with sharp downward action is his best secondary offering and his average changeup induces ground balls and the occasional swing and miss, although he needs to incorporate the pitch more regularly. Pfaadt throws his fastball for strikes in all for quadrants of the strike zone and commands his secondaries. He works hard, studies the game and is eager to improve.

    The Future: Pfaadt quickly has gone from relative unknown to someone many expect to be a major leaguer. His debut may come in 2022 and he has a chance to settle into the middle or back of a rotation.

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