Player Reports

  1. 1. Tyler Skaggs | LHP
    Tyler Skaggs
    Born: Jul 13, 1991
    Bats: L Throws: L
    Ht.: 6'4" Wt.: 225
    Minors: 6-10 | 4.60 ERA | 115 SO | 47 BB | 109.7 IP

    Skaggs was a three-sport star at Santa Monica (Calif.) High, where his mother Debbie was the longtime softball coach. He eventually gave up basketball and football to focus on baseball and pitched his way into the supplemental first round of the 2009 draft. The Diamondbacks hoped to take him with the 41st overall selection, but the Angels beat them to the punch at No. 40. He was part of a strong Angels draft class that already has sent Mike Trout, Skaggs, Garrett Richards, Patrick Corbin and Drew Carpenter to the majors. Skaggs signed for $1 million just before the Aug. 17 deadline, giving up a Cal State Fullerton commitment. Arizona finally got him a year later, acquiring him as the centerpiece of a July 2010 trade for Dan Haren. The Diamondbacks also received Corbin, Rafael Rodriguez and Joe Saunders. Skaggs' fastball velocity and prospect stock have risen in each of his two full seasons with Arizona, and he represented the organization in the last two Futures Games. He ranked as the No. 3 prospect in the Double-A Southern League and No. 4 in the Triple-A Pacific Coast League in 2012, going a combined 9-6, 2.87 with 116 strikeouts in 123 innings before making his major league debut on Aug. 22. He beat the Marlins in his big league start and pitched well in his next two before he tired and his velocity dropped in his next three. Arizona shut him down for the season after the Padres beat him on Sept. 20. The jewel of Skaggs' repertoire is a sharp 12-to-6 curveball that he throws in the mid-70s. It features late, sharp break and is regarded as one of the best in the minors. He set it up with a fastball that ranges from 89-94 mph and features some armside run. He delivers his heater with good downhill plane and spots it to both sides of the plate. He throws in the low 90s more consistently than he ever has, and he also has improved his fastball command. Skaggs' changeup gives him a potential third plus pitch, but he needs to trust it more. It arrives at 78-80 mph, has some fade and plays well off his fastball. He can dominate hitters when all three pitches are working for him. Skaggs has smooth, easy mechanics and uses a high three-quarters arm slot. His athleticism allows him to repeat his delivery and consistently command his pitches. He also stands out for his composure on the mound and his idea of what he needs to do with each hitter. He holds runners well with a strong pickoff move, permitting just five steals in eight attempts last year. He didn't give up a single swipe in his six major league starts. He fields his position well. Skaggs will be just 21 when spring training rolls around, but he has an excellent chance of earning a spot in the Arizona rotation when camp breaks. There's still projection remaining in his lanky frame, so there's a chance he could continue to get stronger and add velocity to his fastball. One of the top lefthanded pitching prospects in the game, he projects as a No. 2 starter.

  2. 2. Trevor Bauer | RHP
    Trevor Bauer
    Born: Jan 17, 1991
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 205
    Minors: 6-7 | 4.15 ERA | 106 SO | 73 BB | 121.3 IP

    Bauer had a storied career at UCLA, setting Bruins career records for wins (34) and whiffs (460) while topping NCAA Division I in strikeouts in consecutive seasons. He won the Baseball America College Player of the Year and Golden Spikes awards in 2011, when the Diamondbacks made him the No. 3 overall pick in the draft and signed him to a big league contract with a $3.4 million bonus and $4.45 million in guarantees. In his first full pro season, Bauer ranked as the Southern League's top prospect, made his big league debut in June and helped Reno win the Pacific Coast League playoffs and the Triple-A National Championship. But his unconventional approach, which includes extreme long-tossing and the desire to call his own pitches, drew criticism from teammates and even owner Ken Kendrick. Bauer lasted just four starts in his first shot at the major leagues, but he still has outstanding stuff. His mid-90s four-seam fastball touches 96 mph and bores in on righthanders. Both it and his hard curveball grade as plus-plus pitches. He also uses a splitter, slider and changeup, all of which are at least average pitches. Bauer needs to refine his plan on the mound. He gets caught up trying to strike out every hitter, which leads to control issues and high pitch counts. Rather than trying to make each pitch perfect, he just needs to trust his stuff. He puts considerable effort into each pitch, but his delivery works for him and adds deception. Bauer will get a fresh start in spring training and a chance to break camp in Arizona rotation. He needs to make some adjustments but has all the ingredients to be a No. 1 starter.

  3. 3. Archie Bradley | RHP
    Archie Bradley
    Born: Aug 10, 1992
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 225
    Signed By: Kyle Denny
    Minors: 14-5 | 1.84 ERA | 162 SO | 69 BB | 152.0 IP

    When the Diamondbacks failed to sign No. 6 overall selection Barrett Loux in 2010, they got the seventh choice in 2011 as compensation. That pick became Bradley, who turned down the chance to play quarterback at Oklahoma for a $5 million bonus. After pitching two innings in his first pro summer, he jumped to low Class A South Bend in 2012, ranking as the Midwest League's top pitching prospect while leading the circuit in opponent batting average (.181) but also in walks (84). Arizona has three potential No. 1 starters in the system, and Bradley has the most electric arm. His fastball ranges from 93-98 mph, though he doesn't always command it well because a high leg kick can throw off his mechanics. At least when he misses, he misses down in the strike zone. Bradley's above-average 12-to-6 curveball gives him a second swing-and-miss pitch, and he's developing feel for an average changeup with nice sink. He has the athleticism and easy delivery to develop solid control, as well as a strong build for durability. He made significant strides with his command during instructional league, so he could really take off in 2013. With a deep pool of pitching prospects ahead of him, the Diamondbacks won't have to rush Bradley, who will spend all or most of the year at high Class A Visalia.

  4. 4. Adam Eaton | OF
    Adam Eaton
    Born: Dec 6, 1988
    Bats: L Throws: L
    Ht.: 5'9" Wt.: 176
    Minors: .256/.367/.378 | 2 HR | 8 SB | 90 AB

    Eaton won the Rookie-level Pioneer League batting title (.385) after signing for $35,000 as a 19th-round college senior in 2010, and he continues to prove that performance was no fluke. He reached the big leagues in 2012, when he also led the minors in batting (.375), hits (198) and doubles (47) and was named Pacific Coast League MVP. He played regularly for Arizona in September before an errant pitch broke his right hand. Though Eaton is undersized at 5-foot-9, he has plenty of tools. His plus-plus speed stands out the most, and he does an excellent job of putting the ball in play so he can use it. He gets to top speed quickly, making him a basestealing threat. He led the PCL with 38 stolen bases in 48 tries last year. A prototypical leadoff hitter, Eaton consistently puts together good at-bats and gets on base. He added more pop to his package in 2012 and now projects as a double-digit home run threat. He also made big strides defensively, convincing scouts that he can be a big league center fielder. He has a strong, accurate arm. Eaton has gone from draft afterthought to potential fourth outfielder to big league regular in two short years. Arizona cleared the way for him to be its everyday center fielder and leadoff hitter by trading Chris Young this offseason.

  5. 5. Matt Davidson | 1B
    Matt Davidson
    Born: Mar 26, 1991
    Bats: R Throws: R
    Ht.: 6'3" Wt.: 230
    Signed By: Jeff Mousser (Diamondbacks)
    Minors: .280/.350/.481 | 17 HR | 1 SB | 443 AB

    The 35th overall pick in the 2009 draft, Davidson signed for $900,000. After sharing third base with 2009 first-rounder Bobby Borchering in their first two full pro seasons, Davidson had the hot corner to himself at Double-A Mobile last year. He improved his defense and slammed a career-high 23 homers. Davidson brings a professional approach and plenty of power to the plate. When he doesn't try to do too much, he can drive the ball to all fields. While he continued to improve his plate discipline in 2012, he'll always accumulate strikeouts and probably won't hit for a high average. The chance to play regularly at third base helped Davidson enhance his range and actions. His 28 errors led SL third basemen by a wide margin, so he needs more consistency, but he has the soft hands and average arm to play there. Better positioning would help him. He's a below-average runner. Arizona needs a starting third baseman and more power bats in its lineup. Davidson still needs some time in Triple-A but should make his major league debut at some point in 2013. He'll push incumbent Chris Johnson aside when he's ready.

  6. 6. David Holmberg | LHP
    David Holmberg
    Born: Jul 19, 1991
    Bats: R Throws: L
    Ht.: 6'3" Wt.: 245
    Signed By: Joe Siers (White Sox)
    Minors: 5-8 | 2.75 ERA | 116 SO | 50 BB | 157.3 IP

    Getting Daniel Hudson from the White Sox for Edwin Jackson was a nice return for the Diamondbacks in their 2010 deadline deal. As an added bonus, they also received Holmberg, a polished lefthander who has breezed through three levels in the last two seasons. One of the most polished pitchers in the system, Holmberg has the best command among Arizona farmhands. He knows how to pitch and can locate four offerings where he wants. His best pitch is a low-80s changeup with sink that he'll use in any situation. He spots his 88-91 mph fastball well, reaching as high as 93. He also has a good feel for a curveball and slider that can become average pitches. Holmberg is extremely poised on the mound and very sound mechanically. He has firmed up what used to be a doughy body and is now stronger and more athletic. Holmberg held his own but didn't dominate in Double-A, so he could open 2013 back in Mobile. He's on track to reach Triple-A before he turns 22 and could make his big league debut in 2014. While he may not match the upside of other pitching prospects in the system, the odds are pretty good that he'll reach his ceiling of a No. 3 or 4 starter.

  7. 7. Chris Owings | OF
    Chris Owings
    Born: Aug 12, 1991
    Bats: R Throws: R
    Ht.: 5'10" Wt.: 185
    Minors: .330/.359/.482 | 12 HR | 20 SB | 546 AB

    When the Angels took Tyler Skaggs with the 40th overall pick in the 2009 draft, the Diamondbacks used the next choice on Owings, who signed for $950,000. Plantar fasciitis in both feet abbreviated his first full pro season, and he struggled with pitch-recognition issues in 2011. He put up the best offensive numbers of his career when he repeated high Class A last year, though he leveled off after a midseason promotion. Owings uses his strong hands to generate above-average bat speed. He has more power potential than most middle infielders and could match the 17 homers he hit in 2012 at higher levels. He used a more compact swing and stayed on pitches better last year, improving his ability to handle curveballs. He still needs to draw more walks, however. Owings should be at least an average big league shortstop, with solid range and a strong arm. He runs well and could steal 20 or more bases on an annual basis once he refines his technique. He'll return to Mobile until he shows he can handle Double-A pitching. If he makes strides similar to 2012, he could reach Triple-A at midseason. Arizona's shortstop position has been wide open since the Stephen Drew trade in August, and Owings could challenge for the job by mid-2014.

  8. 8. Stryker Trahan | OF
    Stryker Trahan
    Born: Apr 25, 1994
    Bats: L Throws: R
    Ht.: 6'0" Wt.: 232
    Signed By: Rusty Pendergrass
    Minors: .254/.328/.462 | 10 HR | 1 SB | 236 AB

    A tough but friendly Cajun kid named after a character in a Burt Reynolds movie, Trahan was the first high school catcher drafted in 2012. The 26th overall pick, he signed for $1.7 million before slugging .473 and leading the Rookie-level Arizona League with 40 walks in his pro debut. Because he's unrefined defensively, he spent the entire summer in the AZL so he could work with hitting coach Robby Hammock and catching coordinator Bill Plummer, both former big league catchers. Trahan's hitting is far ahead of his defense. He has advanced plate discipline, above-average bat speed and the strength to drive the ball out of the park. His plus power is his calling card, but he also has the potential to hit for solid average. Opinions are mixed as to whether Trahan can stay behind the plate despite a strong arm and good athleticism. He threw out just 24 percent of AZL basestealers and his blocking and receiving skills are below-average. He did show improvement during the summer. He runs well enough to play on an outfield corner if he has to move. Trahan has the hitting chops to warrant a move to a full-season team, but he'll likely stay behind in extended spring training to work on his defense at the start of 2013. His next stop likely will be short-season Hillsboro.

  9. 9. Andrew Chafin | LHP
    Andrew Chafin
    Born: Jun 17, 1990
    Bats: R Throws: L
    Ht.: 6'2" Wt.: 225
    Signed By: Nate Birtwell
    Minors: 13-8 | 3.20 ERA | 119 SO | 55 BB | 157.3 IP

    After signing Chafin for $875,000 as the 43rd overall pick in 2011, the Diamondbacks challenged him with a jump to high Class A in his first full pro season. He dominated in his first 10 starts, recording a 2.91 ERA and 77 strikeouts in 59 innings, before tiring and pulling bullpen duty for a month. The fatigue wasn't unexpected, considering it was just his second year back from Tommy John surgery, and he recovered to lead the California League in strikeouts per nine innings (11.0) and opponent average (.241). Chafin has the best slider in the system and it can be unhittable for both lefties and righties. He throws his 90-94 mph four-seam fastball to both sides of the plate, and he also uses a two-seamer with sink. He focused more on his average changeup when pitching in relief and began to use it more in the second half. Chafin's delivery lacks fluidity and features some upper-body tilt, leading some scouts to believe he might be better suite for the bullpen. He has the repertoire to remain in the rotation, though he'll need to stop nibbling so much and trust his stuff more. Scouts noted a more aggressive approach during instructional league. Chafin is ready to move to Double-A. He has a realistic ceiling of a mid-rotation starter or set-up man.

  10. 10. A.J. Pollock | OF
    A.J. Pollock
    Born: Dec 5, 1987
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 212

    The Diamondbacks expected Pollock to move quickly after signing him for $1.4 million as the 17th overall pick in 2009, but he missed the following season when he fractured a growth plate in his right elbow during spring training. He has made up for lost time by batting .312 in the upper minors during the last two seasons and getting three separate big league callups in 2012. Pollock's total package is more than the sum of its parts, with only his bat and makeup grading better than average. He's a gap-to-gap hitter who makes reliable contact but has yet to develop much over-the-fence power. The ball does come off his bat well, so Arizona believes he will eventually produce 10-15 homers per year. Pollock makes the most of his average speed, running the bases well and showing annual 20-steal potential. He's capable of playing all three outfield positions, getting good reads and displaying an average arm that's enough to handle right field. Scouts are split on Pollock, with some seeing him as a solid regular in center field and others thinking he profiles best as a fourth outfielder. The Diamondbacks have no shortage of starting outfield candidates in Adam Eaton, Jason Kubel, Gerardo Parra and Justin Upton, so Pollock will have to settle for a reserve role in 2013.

  11. 11. Chase Anderson | RHP
    Chase Anderson
    Born: Nov 30, 1987
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 200
    Minors: 4-7 | 5.73 ERA | 80 SO | 33 BB | 88.0 IP

    Anderson was a reliever at Oklahoma prior to signing for $85,000 as a ninth-round pick in the 2009 draft, but the Diamondbacks have developed him as a starter. He missed nearly all of the 2011 season with a strained flexor tendon in his forearm that didn't require surgery, and Arizona was cautious with him last year by limiting most of his Double-A starts to five innings. He was the Game One starter for Mobile in both of its playoff series, helping the BayBears win their second straight Southern League championship. Anderson possesses the best changeup in the system. It's at least a plus pitch with excellent fade, and he doesn't hesitate to use it when behind in the count. While his fastball sat in the high 80s early in the season, he worked at 90-94 mph in the Arizona Fall League while maintaining good command. He delivers his curveball in the mid-70s with good depth, giving him an effective third pitch. He's also working on a slider and eventually could have four average or better offerings. Anderson throws with a high three-quarters arm slot and repeats his delivery. A strong AFL performance earned him a spot on the 40-man roster and enhanced his credentials as a potential No. 4 starter. He'll move up to Triple-A in 2013.

  12. 12. Michael Perez | C
    Michael Perez
    Born: Aug 7, 1992
    Bats: L Throws: R
    Ht.: 5'10" Wt.: 195
    Minors: .208/.261/.343 | 7 HR | 1 SB | 341 AB

    Perez, who signed for $235,000 out of the 2011 draft, took a big step forward in his first full pro season, showing the skills on offense and defense to be a potential starting major league catcher. Perez is a free swinger at the plate, striking out 72 times in 225 at-bats last season, but he squares up the ball well, makes solid contact and uses the whole field. He shows enough power that he might one day hit 20 homers a season. He had limited catching experience as an amateur, so he has made significant strides defensively. He's calm behind the plate, his footwork and exchange are good, and he blocks well. He has an above-average arm that could get stronger as he matures, and he threw out 52 percent of basestealers last year, the best figure in the Rookie-level Pioneer League. While some had concerns about whether he was big enough to handle the everyday rigors of catching, Perez got bigger and stronger in 2012 and now has a solid catcher's build. Scouts note that he resembles Miguel Montero in how he goes about his business on the field. With a surplus of catching prospects in the low minors, the Diamondbacks could choose to give Perez more time in short-season ball, but he is probably ready for a full-season assignment to South Bend.

  13. 13. Anthony Meo | RHP
    Anthony Meo
    Born: Feb 19, 1990
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 185
    Minors: 1-5 | 6.83 ERA | 39 SO | 47 BB | 58.0 IP

    Meo was one of many college power arms that the Diamondbacks picked early in the 2011 draft, going in the second round after a strong junior season at Coastal Carolina. Like supplemental first-rounder Andrew Chafin, Meo was challenged with an assignment to high Class A in his first full pro season, and he responded well, tying for the California League lead with 153 strikeouts. Meo's best pitch is a 90-94 mph fastball and he shows the ability to maintain his velocity deep into his starts. His slider can be nasty at times, and he's developing a feel for a changeup. Meo pitches with a lot of effort, with a wrap in his arm action, and struggles repeating his delivery, so he probably profiles better in the bullpen, where his fastball and slider would play up. He could potentially be a late-inning reliever because of the good movement on his two-seam fastball. Meo will stay in the rotation for now, likely moving up to Double-A in 2013.

  14. 14. Evan Marshall | RHP
    Evan Marshall
    Born: Apr 18, 1990
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 225
    Minors: 3-6 | 4.34 ERA | 59 SO | 30 BB | 58.0 IP

    Marshall began his Kansas State career as a starter before moving to the bullpen and finding it suited him well. He was part of the Diamondbacks' infusion of pitching from the 2011 draft, signing for $232,500, and they have kept him in a relief role. He pitched at three levels in his pro debut, finishing the year in Double-A, then returned to that level for the entire 2012 season, closing games for Mobile as the team won a second consecutive Southern League championship. Marshall primarily uses a fastball/slider combination, with his biggest strength being average to plus command and the ability to keep the ball on the ground. His 91-93 mph fastball has good armside run and sink, and he has a decent feel for a slider. He worked on his changeup in the Arizona Fall League, so he now has a legitimate three-pitch mix. A lack of swings and misses may prevent Marshall from being an elite reliever. His maximum-effort delivery has him flying open quickly, which provides deception. Marshall will move to Triple-A in 2013 and could be one of the first relievers called to the big leagues when a need arises.

  15. 15. Keon Broxton | OF
    Keon Broxton
    Born: May 7, 1990
    Bats: R Throws: R
    Ht.: 6'3" Wt.: 195
    Minors: .231/.296/.359 | 8 HR | 5 SB | 334 AB

    Broxton is another product of the rich 2009 draft, signed by the Diamondbacks away from a Florida Atlantic football commitment so he could try to translate his athleticism on the baseball diamond. A slow start in high Class A last season had some scouts jumping off the bandwagon, but something clicked in the second half and he finished strong, batting .333/.361/544 with 11 homers. That surge landed him on Arizona's 40-man roster in November. The key for Broxton was playing off his strengths and becoming more aggressive in hitting the fastball, allowing his power to emerge. He already plays major league-quality defense in center field. His plus speed and good routes and jumps in the outfield make him a plus defender, and his arm is also a plus tool. Below-average pitch recognition and difficulties with the curveball continue to be his biggest weaknesses and will determine if he reaches the big leagues. He is a hard worker with good makeup and has consistently ranked as the most athletic player in the system, but he's still a long way from proving he can be a big league regular.

  16. 16. Jake Lamb | 3B
    Jake Lamb
    Born: Oct 9, 1990
    Bats: L Throws: R
    Ht.: 6'3" Wt.: 215
    Signed By: Donnie Reynolds
    Minors: .302/.421/.548 | 13 HR | 0 SB | 248 AB

    Lamb earned honorable mention all-Pacific-12 Conference recognition to wrap up his career at Washington, before the Diamondbacks picked him in the sixth round last June and signed him for $161,000. He began his pro career at Rookie-level Missoula, leading the team with a .929 OPS. Lamb stands out for his athleticism and his defense at third base, with his plus arm ranking as the best infield arm in the system. He has plus raw power that is starting to translate to game power and could grow as he matures physically, learns to hit off the fastball and adjusts better to offspeed pitches. His swing still gets a little too long. He's an adequate baserunner, stealing eight bases in 10 attempts at Missoula. Lamb plays the game the right way and is a hard worker. Scouts give him a legitimate chance to be a big league regular. After showing good progress in instructional league, he may be advanced enough to open 2013 in low Class A.

  17. 17. Jon Griffin | 1B
    Jon Griffin
    Born: Apr 29, 1989
    Bats: R Throws: R
    Ht.: 6'6" Wt.: 230
    Minors: .259/.312/.389 | 10 HR | 0 SB | 386 AB

    The Diamondbacks took Griffin as a low-cost senior sign in 2011 out of Central Florida, where he earned all-Conference USA honors in his final year after batting .343/.394/.661 with 19 homers. He then hit 18 homers to lead the Pioneer League after signing, prompting Arizona to jump him to high Class A in his first full pro season. He continued to show his power potential, belting 28 homers and 102 RBIs as he moved up to Double-A for the end of the regular season and Southern League playoffs. Griffin has exceptional raw pop and it should translate into at least average game power at the big league level. He improved his approach at the plate, cutting his strikeout rate from 28 percent to 21 percent despite the two-level jump, and showed the ability to turn on balls in or adjust on balls away. He has good bat speed but a long swing path, and a tendency to cheat on the fastball. He's athletic for his size and has been a better defender than Arizona expected, with soft hands. Griffin has been compared to Paul Goldschmidt for his work ethic and preparation, and like Goldschmidt before him, Griffin will have to prove he can hit quality pitching as he moves up.

  18. 18. Alfredo Marte | OF
    Alfredo Marte
    Born: Mar 31, 1989
    Bats: R Throws: R
    Ht.: 5'11" Wt.: 200
    Minors: .280/.335/.431 | 7 HR | 2 SB | 311 AB

    Marte spent six years in the system without getting much recognition as a prospect until he broke out with a strong 2012 season in Double-A, earning him a spot on the World team in the Futures Game. After never hitting more than nine homers in any previous season, he went deep 20 times for Mobile in only 398 at-bats. Marte became more confident at the plate and carried over improvements he made in high Class A in 2011. He's aggressive at the plate and takes a big swing, but he has developed a better feel for hitting and made more solid contact in Double-A. He projects to be more of a gap-to-gap, doubles hitter but should be able to consistently hit 15-20 homers a year. He draws comparisons to Chris Young for his athleticism, and while speed is not expected to be a factor in his game, he's an average runner with average range in the outfield. Marte is better suited to a corner, and his average arm should be enough to handle right field. He missed time in 2012 with a hamstring injury, but he finished strong to earn a spot on Arizona's 40-man roster and should be ready for a move to Triple-A.

  19. 19. Jake Barrett | RHP
    Jake Barrett
    Born: Jul 22, 1991
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 240
    Signed By: Matt Smith
    Minors: 3-2 | 1.21 ERA | 59 SO | 12 BB | 52.0 IP

    Barrett played his high school ball in the Phoenix area, leading Desert Ridge High to a 2009 state championship. The Blue Jays took him in the third round that June but he chose to go to Arizona State instead. He moved from the rotation to a closer role in 2012 with the Sun Devils and was again a third-round pick, this time signing with the hometown Diamondbacks for $392,900. He jumped to full-season ball with South Bend and got knocked around a bit. Barrett has two plus pitches in his power arsenal, combining a 93-96 mph fastball that hits 98 with a hard slider. He worked on a changeup after signing, but it still lacks consistency. He has the big frame, demeanor and pitches to be a late-inning reliever. Fatigue and the adjustment to the grind of professional baseball caused Barrett's velocity and command to drop last season, but he should be ready for an assignment to high Class A in 2013. He has the repertoire to move quickly in an organization that values power bullpen arms.

    Ht.: 6'3" Wt.: 200
    Minors: 7-5 | 4.55 ERA | 50 SO | 19 BB | 89.0 IP

    Perez had the talent to go in the third to fifth round of the 2012 draft, but a strong UCLA commitment caused him to go unselected. His stuff took a step forward when he pitched in a summer collegiate West Coast League, and with money left in their draft budget the Diamondbacks signed Perez as a nondrafted free agent for $400,000 just before he was to head to campus. He reported to the Arizona minor league complex but did not pitch in games until instructional league. Right now, Perez is more about arm strength and he shows limited feel for pitching. His fastball sits at 91-93 mph with average movement, sink and tail. His curveball has late break and his changeup has good tumble and works well off the fastball. His high three-quarters delivery is clean with good arm action. Perez can throw all three of his pitches for strikes, and they all project to be average or better pitches in time. He's very coachable and mature for his age. Perez will start the 2013 season in extended spring training before reporting to a short-season club.

    Bats: R Throws: R
    Ht.: 6'3" Wt.: 195
    Minors: .263/.342/.448 | 6 HR | 5 SB | 194 AB

    Munoz didn't play in as many showcases as higher-profile Southern California high school prospects, so his draft stock was harder to judge. The Diamondbacks liked his natural shortstop frame, instincts on the field and power potential, so they made him a second-round pick and signed him away from San Diego State for $520,500. The comment most often made about Munoz is that he just looks like a shortstop, and one of his Arizona League coaches said: "You can't draw a better shortstop body than what he's got." Munoz's inexperience in the field showed in his first season, as he made 25 errors in 45 games, most from troubles with his footwork. He has the potential to be an above-average defender with enough arm for shortstop, and should be able to stay at the position unless he eventually grows too big. His defense is ahead of his offense right now, although he hit better in the latter half of the AZL season after making adjustments to his approach, and he put together nice at-bats in instructional league. Munoz shows good power in batting practice and projects to be an average hitter. He's a tick below-average runner. Scouts in the AZL thought that Munoz could be a late bloomer, and he'll certainly need another year of short-season ball.

    Born: Jan 27, 1994
    Bats: R Throws: R
    Ht.: 5'11" Wt.: 193
    Minors: 6-6 | 3.12 ERA | 60 SO | 40 BB | 83.7 IP

    Eckels is an undersized righthander whose repertoire and bulldog mentality would have put him in the early rounds of the 2012 draft if he were two or three inches taller. The Diamondbacks grabbed him in the 11th round and signed him for a $125,000 bonus, steering him away from a commitment to Howard (Texas) JC. He quickly became a favorite of scouts covering the Arizona League, where he struck out 56 batters in 52 innings, and he may turn out to be one of the better sleepers of the draft. Eckels stands out for his composure and aggressiveness on the mound. His low-90s fastball has heavy sink, and he also has a promising curveball and changeup. He pitches aggressively in the zone and has the ability to throw all of his pitches for strikes. Eckels will likely head to a more advanced short-season stop in 2013, but with his advanced feel for pitching and command of three pitches, he might be able to earn an assignment to low Class A.

    Born: Jun 18, 1990
    Bats: R Throws: R
    Ht.: 5'11" Wt.: 195
    Minors: 4-9 | 5.43 ERA | 110 SO | 48 BB | 116.0 IP

    Winkler was the ace of the Texas Christian staff as a junior, going 8-2, 1.39 and looking like a likely first-round pick before coming down with an arm injury just before the 2011 draft. Arizona still took him in the 10th round, signing him for $240,000 just after he had surgery for a stress fracture in his elbow. He rehabbed at the Diamondbacks' complex for the rest of 2011, making his pro debut in 2012 in the Visalia bullpen. Winkler gets hitters out with a 93-95 mph fastball and a hard slider. His changeup looked much better in instructional league, when he was throwing it with nice fade and sink. He has a funky delivery in which his arm comes through late, putting some stress on his elbow, but it provides deception as he steps toward the plate. Winkler profiles as a reliever but may start some in the minors in order to get more innings under his belt and build up arm strength.

  24. 24. Andrew Velazquez | SS
    Andrew Velazquez
    Born: Jul 14, 1994
    Bats: B Throws: R
    Ht.: 5'8" Wt.: 170
    Drafted: HS--Bronx, N.Y., 2012 (7th round).
    Signed By: Todd Donovan (Diamondbacks).
    Minors: .260/.319/.336 | 0 HR | 7 SB | 235 AB

    Arizona scouted Velazquez in the summer before his senior year of high school and kept tabs on his progress before drafting him last June and signing him quickly for $200,000. After playing shortstop in high school, Velazquez spent most of his first pro season at second base, and that's where he looks best suited. The undersized infielder quickly became a favorite both of the Diamondbacks' Arizona League coaching staff and scouts covering the league for his athleticism, speed and gamer mentality on the field. Velazquez has good hands that help him generate above-average bat speed. His raw speed is above-average, and it plays up because he's a smart baserunner, stealing 22 bases in 25 attempts in his first season. He doesn't yet have much power (his only homer was inside the park), but started to show a little more pop during instructional league and could eventually hit 10-15 homers a year. While he's still relatively new to the infield, having been an outfielder earlier in his high school career, he should be a solid defender. He's capable of playing either middle-infield position, with enough arm for shortstop. Velazquez will need lots of development time, so he'll probably return to a short-season team in 2013.

  25. 25. Jose Martinez | RHP
    Jose Martinez
    Born: Apr 14, 1994
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 160
    Signed By: Junior Noboa
    Minors: 2-3 | 4.03 ERA | 30 SO | 25 BB | 38.0 IP

    Martinez signed in 2011 for $55,000 under the name Jose Fermin. His fastball sat at 85-88 mph at the time, but shortly thereafter his velocity increased to 90-91 and he developed a harder-breaking curveball. Martinez made a strong pro debut at age 18 in the Rookie-level Dominican Summer League last season and was named the Diamondbacks' minor league pitcher of the month for July. He came to the United States for two late-season starts with short-season Yakima before reporting to Arizona for instructional league. Martinez commands his lively 91-96 mph fastball, and he could add more velocity as he gets bigger and stronger. He's got a tight power curveball that is tough to hit when he commands it, and a changeup that is still a work in progress. Martinez has an ideal, athletic pitcher's frame, fluid arm action and an over-the-top delivery that he repeats well, though with some effort. He keeps the same arm speed with all of his pitches. Martinez handled his late stint in Yakima well considering it was his first time in the United States. He's probably not yet ready for a full-season assignment and could return to the short-season Northwest League.

  26. 26. Starling Peralta | RHP
    Starling Peralta
    Born: Nov 11, 1990
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 210
    Minors: 2-4 | 6.60 ERA | 53 SO | 33 BB | 60.0 IP

    Peralta spent three years in the Cubs' Dominican Summer League program before making his U.S. debut in 2011, starting with three games in Rookie ball before jumping to low Class A Peoria. He returned to Peoria in 2012 with better results after an early season hand injury, holding hitters to a .199 average in the second half. The Diamondbacks selected Peralta in the Rule 5 draft during the 2012 Winter Meetings when Chicago left the lanky righthander off the 40-man roster in his first year of eligibility. His fastball averages 94 mph and gets as high as 97. He pitches with a short-arm, upright delivery that is not loose and leads to command issues. Peralta tends to get slider happy at times instead of trusting the fastball, but the slider has the potential to be an average pitch. His third pitch is a below-average changeup that he seldom uses. With a two-pitch mix and effectiveness against righthanders, Peralta profiles better as a bullpen arm, and he'll attempt to make the Arizona roster in that role. The Diamondbacks have a history of making trades to retain Rule 5 picks they like and may do so again if he impresses during spring training. They can't send him to the minors in 2013 without exposing him to waivers and offering him back to the Cubs for half of his $50,000 draft price.

    Born: Nov 24, 1991
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 185
    Minors: 0-0 | 5.34 ERA | 25 SO | 17 BB | 28.7 IP

    Green was on his way to Texas Christian as a two-way player before the Diamondbacks signed him at the 2010 deadline for an above-slot $750,000 bonus. He spent both of his first two professional seasons at South Bend, pitching mostly in the rotation, although his violent delivery and control issues indicate that he will likely wind up in the bullpen before long. Green's best pitch is an 88-92 mph fastball that gets up to 95 mph with good sink and angle. He also uses a power curveball and is starting to develop a better feel for a below-average changeup. Green's over-the-top delivery provides deception but also leads to command issues. He started to find himself late in the season when his work ethic and pitchability improved. Green will move up to high Class A, and he may wind up in a relief role where his bulldog mentality and power arsenal will play up well.

  28. 28. Kevin Munson | RHP
    Kevin Munson
    Born: Jan 3, 1989
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 215
    Minors: 2-4 | 4.12 ERA | 66 SO | 22 BB | 54.7 IP

    Munson was a catcher at the beginning of his college career at James Madison but was quickly moved to the mound to take advantage of his arm strength. The Diamondbacks took Munson in the fourth round in 2010 and started him in full-season ball, assuming that he could move quickly and help the big league club sooner rather than later. Instead, command issues have plagued him throughout his career, caused in part by a delivery in which he opens up early, causing the stuff to flatten out and come up. He's no longer considered to have closer potential, but still possesses a 91-95 mph fastball that touches 97, as well as a hard slider. He fields his position well and displays good mound presence. Munson improved his command after the season's first two months and was dominating hitters by the end of the year, posting a 0.84 ERA with 16 strikeouts in 11 innings in August. His 2013 Opening Day assignment will depend on which Munson shows up in spring training.

    Ht.: 6'2" Wt.: 205
    Signed By: Junior Noboa
    Minors: .264/.313/.356 | 2 HR | 27 SB | 523 AB

    The Diamondbacks signed Brito out of the Dominican Republic for $190,000, then voided the deal when he failed a steroid test and re-signed him for $90,000 two months later. That small investment may pay off, though Brito is still a long way from the big leagues. One scout said that Brito has the biggest gap between his present and future grades, but that he's still someone to dream on. Brito spent his second year in the United States at Missoula, showing speed but no power. While his in-game power has not yet emerged, he shows enough pop in batting practice to prove that he will hit with power when he fills out his wiry strong frame and improves his pitch selection. Brito is one of the fastest players in the system once under way, and his speed gives him good range in the outfield, although his routes are sometimes poor. He has plus arm strength and is improving his accuracy. He is still years away but has the tools to profile as a big league regular if he figures everything out. He'll advance to low Class A in 2013.

  30. 30. Evan Marzilli | OF
    Evan Marzilli
    Born: Mar 13, 1991
    Bats: L Throws: L
    Ht.: 6'0" Wt.: 185
    Minors: .250/.342/.346 | 3 HR | 14 SB | 460 AB

    Marzilli was a key part of three straight College World Series runs at South Carolina, including national titles in 2010 and 2011. After the Gamecocks finished runner-up in 2012, he signed for $132,900 as an eighth-round pick. His knack for playing on winning teams continued, as he helped Missoula reach the Pioneer League playoffs, but a broken arm put him out of action for the playoffs. Marzilli is athletic with a deceptively strong body. Center-field defense is his strongest skill, and he's a plus defender with plus speed and excellent instincts. He worked hard on his throwing in school so that he now has an average arm. At the plate, Marzilli has a short, quick stroke and uses the whole field. He doesn't hit with much power, so he's best suited as a top of the order hitter, but he needs to work on plate discipline and understand how to work counts. His speed hasn't yet translated to stolen bases, something that the Diamondbacks will emphasize in his development plan. Marzilli is a grinder with an outstanding work ethic, and he brings a winning attitude to the game thanks to his three years in the South Carolina program. Because of his major college experience, Marzilli may be ready for full-season ball in 2013.
