Diamondbacks Designate Alek Thomas For Assignment, Promote Ryan Waldschmidt
The D-backs are cutting ties with one former top outfield prospect in order to turn the page toward a new one. Arizona announced Friday that Alek Thomas has been designated for assignment, while top prospect Ryan Waldschmidt‘s contract has been selected to the majors. Waldschmidt, currently the game’s No. 41 prospect on Baseball America’s recent top-100 update, figures to get regular work in the outfield moving forward. The Snakes also activated first baseman Tyler Locklear from the injured list and optioned him to Triple-A Reno.
Now 26 years old, Thomas was a second-round pick out of high school back in 2018 and quickly became not only one of the game’s top-ranked outfield prospects but its top-ranked prospects overall. From 2020-22, Thomas was a consensus top prospect on lists at Baseball America, MLB.com and several other outlets. He climbed as high as No. 32 on BA’s rankings in 2022 and all the way up to No. 18 over at MLB.com.
While Thomas didn’t exactly hit the ground running in 2022, he showed decent bat-to-ball skills, good speed and a quality glove in his first taste of big league action. After slashing .322/.397/.539 (125 wRC+) in Triple-A Reno to earn his big league promotion that year, he hit .231/.275/.344 with eight homers in 411 plate appearances during his first taste of the majors.
That was nearly 30% worse than league-average production, per wRC+, but Thomas showed 95th percentile sprint speed and logged positive marks in both Defensive Runs Saved (7) and Outs Above Average (7). It’s easy enough to overlook a shaky offensive showing for a 22-year-old in his MLB debut when the other tools are present, and Thomas had a nice speed-and-defense floor with an 18% strikeout rate that sat well shy of league average.
Unfortunately, Thomas’ bat has yet to come around. He’s now played in parts of four major league seasons. He’s never topped nine homers or an 81 wRC+. He’s a career .230/.273/.361 hitter in 1485 plate appearances and has seen his strikeout rate climb since that rookie showing. Thomas struck out at an alarming 26% clip last season (in a career-high 469 plate appearances) and is at 23% this season while batting .181/.222/.340. He’s out of minor league options, and a D-backs club that ranks 19th in runs scored and 22nd in home runs clearly feels it can no longer wait for an offensive breakout that may simply never manifest.
Waldschmidt, 23, entered the season as a top-tier prospect and has done nothing to change that outlook. The former No. 31 overall draft pick has taken 156 plate appearances in Reno and delivered a .289/.400/.477 batting line with three homers, nine doubles, three triples, six steals, a huge 12.2% walk rate and a 24.4% strikeout rate. He’s a 6′, 205-pound outfielder who bats from the right side and has plus raw power that has yet to fully be displayed in game settings just yet. Last year’s 18 homers are a career-high, but he’s a potential 20- to 30-homer bat with a good idea of the strike zone, above-average speed and experience in all three outfield spots.
Most scouting reports think Waldschmidt will settle in as a corner outfielder, but he’s played primarily center this season and could take over for Thomas in that regard. The primary alternative in center would be Corbin Carroll, but he’s a plus right field defender in his own right, and Arizona may not want to rankle things by flipping two outfielders to positions they haven’t been playing this season.
While some top prospects get the call without a path to a clear everyday role — typically when they’re filling in for an injured player — that’s not the case with Waldschmidt. Thomas’ removal from the 40-man roster and the lack of any clear everyday outfield alternatives gives him an immediate everyday opportunity and a chance to cement himself as a long-term piece in the outfield mix right out of the gate.
Though Waldschmidt is a consensus top-100 prospect, he won’t be eligible to net the Diamondbacks any compensatory draft picks via MLB’s prospect promotion incentives. Too much time has past for him to qualify. Enough time has also elapsed that Waldschmidt cannot organically accrue a full year of major league service. His only path to doing so would be a top-two finish in this season’s NL Rookie of the Year balloting. Given his pedigree and prospect status, there’s a chance for him to do so, but players like Nolan McLean, Sal Stewart and JJ Wetherholt have a large head-start on him.
In all likelihood, Waldschmidt will finish the season shy of one year of big league service. That’d make him controllable for six years beyond the current campaign, all the way through 2032. The timing of his call to the big leagues does set him up nicely to reach Super Two designation, which would make him arbitration-eligible four times rather than the standard three, so long as he’s not optioned back to the minors. If that’s the case, the first of those four trips through arbitration would come in the 2028-29 offseason.
Turning back to Thomas, the D-backs will have five days to trade him or place him on outright waivers. (They could also release him, but they surely won’t go that route.) Given his speed, defensive chops and former prospect pedigree, Thomas will likely appeal to some outfield-needy clubs who hope to strike big on a change-of-scenery candidate. Teams like the Astros, White Sox, Nationals, Rockies, Royals, Tigers and Cardinals are either rebuilding or facing various outfield injuries that could make Thomas hold some appeal, even as a short-term stopgap.
A contender with a deeper outfield mix but thin bench could also look to add him in a reserve capacity. Thomas is earning a modest $1.926MM this season, so he certainly isn’t going to break the bank. He’s also controllable for two more years beyond the current season, so if another team can get him to even produce slightly below-average offense with some degree of consistency, they could get multiple years of value from the once-touted outfielder.
Jordan Lawlar To Miss Six To Eight Weeks With Broken Wrist
Diamondbacks outfielder Jordan Lawlar has a right wrist fracture, manager Torey Lovullo tells reporters, including Nick Piecoro of The Arizona Republic. He will miss six to eight weeks. The Diamondbacks have placed him on the 10-day injured list. Catcher Adrian Del Castillo was reinstated from the 10-day IL in a corresponding move. Arizona also made a move on the pitching side. They selected the contract of right-hander Taylor Rashi and designated fellow righty Joe Ross for assignment. Prior to the official announcement, Piecoro noted that Rashi had the locker previously occupied by Ross.
It’s yet another unfortunate chapter in the Lawlar story. The youngster has been one of Arizona’s top prospects for years but hasn’t been able to cement himself in the big leagues. He has often been blocked by more established players. When an opening would appear, Lawlar would himself be hurt or would struggle. He finished 2025 with a .165/.241/.237 line in 108 big league appearances.
The club grew impatient with his infield defense and moved him to the outfield for 2026. He earned an Opening Day spot and was hitting well. He hit his first major league home run last night, pushing his season-long batting line to .333/.400/.556 by the end of the game. Unfortunately, he was hit on his wrist by a pitch in the seventh inning. He stayed in the game to run the bases but was replaced defensively in the top of the eighth. Now Lawlar is slated for another notable absence, once again delaying his path to becoming an established big leaguer.
For the Snakes, their outfield takes a hit. They still have Corbin Carroll in right and Alek Thomas in center but Lawlar’s injury means they will have to figure out what to do in left. Lourdes Gurriel Jr. and Pavin Smith could be part of the solution down the road but both are currently on the IL. Del Castillo is unlikely to help, as his outfield experience consists of two Triple-A innings back in 2023. He was likely only called up because the Diamondbacks have no one else to turn to. Every position player on the 40-man roster is either on the active roster or injured list.
For now, they will likely use some combination of Jorge Barrosa, Tim Tawa and Ildemaro Vargas. Piecoro says they decided against calling up prospect Ryan Waldschmidt because that would require a 40-man spot and Gurriel is expected back soon.
Turning to the pitching staff, the Diamondbacks signed Ross to a minor league deal in the offseason. The veteran swingman cracked the Opening Day roster but has been lit up so far. He has allowed eight earned runs in 3 2/3 innings, giving him an unsightly 19.64 earned run average. That’s obviously a small sample size but Ross also issued four walks compared to just two strikeouts.
Arizona was crushed last night, losing 17-2 to Atlanta. Ross did what he could to spare the staff, tossing two innings, but he threw 52 pitches in the process and likely wasn’t going to be available for a few days. He’ll now head into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so Arizona could spend as long as five days exploring trade interest. If Ross clears waivers, he has enough service time to reject an outright assignment and elect free agency.
Rashi, 30, got to make his major league debut with the Diamondbacks last year. He posted a 4.41 ERA in 16 1/3 innings. His 11.1% walk rate was high but he struck out 30.6% of batters faced and induced grounders on 42.9% of balls in play. He was non-tendered at the end of the season but then was re-signed via a minor league deal. He began the season at Triple-A Reno and made one scoreless appearance of an inning and two thirds.

Diamondbacks Notes: Kelly, Waldschmidt, Outfield
Diamondbacks right-hander Merrill Kelly has been battling some back tightness this week. A quick diagnosis was expected but the issue is dragging on a bit longer than initially anticipated, as detailed by Nick Piecoro of The Arizona Republic.
The issue first cropped up on Saturday, which led to Kelly being scratched from a live batting practice session. He was sent for an MRI and those results were expected to be announced on Monday. He has instead been sent for additional testing, including a CT scan, with the club still avoiding any kind of official announcement on his status.
“It’s a wide range,” manager Torey Lovullo said. “I’m not going to lie. We’re being very thorough with what we’re doing. We’re taking every test necessary to make sure that we get everything in the bag before we start to pass that information along. We’ve got to figure out exactly what’s happening in there.”
Time will tell if this is just the club being cautious or if it’s a sign the injury is more significant than anticipated. If Kelly has to miss any time, it would be less than ideal for a club with subpar rotation depth. Right now, they project to have Kelly alongside Zac Gallen and Ryne Nelson with Eduardo Rodríguez, Brandon Pfaadt and Michael Soroka battling for two spots. If Kelly is on the shelf, then everyone in that group would be in line for rotation gigs to open the season.
The Snakes also have Yilber Díaz, Cristian Mena, Kohl Drake, Mitch Bratt and Dylan Ray on the 40-man roster and the guys in that group could suddenly jump to next-man-up status. No one in that cluster has even 32 big league innings pitched. Non-roster invitees with some big league experience include Joe Ross, Thomas Hatch and Bryce Jarvis.
Elsewhere, Arizona has a fairly wide open outfield group. They traded away Jake McCarthy in the offseason and Corbin Carroll require hamate surgery, meaning he could start the season on the injured list. Lourdes Gurriel Jr. is recovering from last year’s surgery to repair the torn anterior cruciate ligament in his right knee. He was expected to be out until the All-Star break. There are some signs he could beat that timeline but he is still projected to start the season on the IL.
That leaves Alek Thomas as the lone guy seemingly locked into a spot. Jordan Lawlar could be in there as well, though he is still getting accustomed to the outfield after coming up as an infielder. He also hasn’t hit at the big league level yet, though he has destroyed the minors and is out to a strong start this spring.
That leaves a path open for prospect Ryan Waldschmidt and Piecoro writes that the club hasn’t ruled out the possibility of him breaking camp with the club. It would be fairly bold if the Snakes ultimately went down that path. Waldschmidt topped out at Double-A last year and isn’t yet on the 40-man roster. But he can clearly hit, as shown by last year’s .289/.419/.473 slash line and 142 wRC+. He hit a home run off Pedro Avila of the Guardians in yesterday’s Cactus League game.
Waldschmidt is a consensus top 100 prospect in the league, so he would be eligible for the prospect promotion incentive if he cracked the Opening Day roster. If he went on to win Rookie of the Year or finish top three in MVP voting during his pre-arbitration years, the Snakes would net a future draft pick just after the first round.
It’s possible there’s a great amount of fluidity in the Arizona outfield this year. Between Carroll, Thomas, Gurriel, Waldschmidt, Lawlar, Jorge Barrosa, Pavin Smith and Tim Tawa, they have a number of options in the mix, with health and performance surely to shuffle the depth charts over the months to come.

Notable Draft Signings: 7/24/24
A handful of draft prospects have agreed to $2MM+ bonuses over the past two days. Unless otherwise noted, bonuses were first reported by Jim Callis of MLB.com. Pre-draft rankings and scouting reports are provided by Keith Law of the Athletic, Baseball America, FanGraphs and ESPN’s Kiley McDaniel.
- Padres first-round pick Kash Mayfield agreed to terms at $3.4421MM. That’s full slot value for the 25th pick to keep him from attending Oklahoma State. Mayfield was the second high school pitcher off the board. The 6’4″ southpaw has a three-pitch mix, advanced control, and can touch 97 MPH. He’s a potential mid-rotation arm. San Diego went with another high school pitcher, Boston Bateman, in the second round. Baseball America’s Carlos Collazo reports (on X) that he lands an above-slot $2.5MM bonus. Bateman is a massive left-hander with mid-90s velocity and a good slider, but his 6’8″ frame leads to questionable command projection. He’d been committed to LSU.
- The Brewers agreed to a $3.44MM bonus with first-round pick Braylon Payne. Milwaukee selected the Texas high school outfielder with the 17th selection. Payne was not generally expected to go in the first round. McDaniel was highest on him, ranking 38th in his pre-draft list. Milwaukee cut an underslot deal but still paid Payne like a late first-round talent to sign him out of a commitment to the University of Houston. Evaluators credit Payne with at least 70-grade speed and the ability to stick in center field, though there’s some skepticism about his offensive upside. Second-round pick Blake Burke landed a $2.1MM bonus, Collazo reports (X link). A first baseman from the University of Tennessee, he hit .379/.449/.702 this season.
- The Dodgers signed #23 pick Kellon Lindsey for $3.3MM, as first reported by J.P. Hoornstra of the Southern California News Group. That’s a bit below the approximate $3.68MM slot value. Lindsey is a high school infielder who’d been committed to Florida. He’s a top-of-the-scale runner who could eventually fit in center field, though he has played shortstop in high school. All four outlets note that Lindsey has similarities to Trea Turner at the same age, though that’d clearly be at the very high end of his range of outcomes. He’s listed at 6’0″ and 175 pounds and might have limited power but could offer a traditional leadoff profile.
- Rangers first-round pick Malcolm Moore signed for $3MM. That’s just above slot for the 30th selection. A Stanford product, Moore is a left-handed hitting catcher. He’s regarded as a bat-first player with questions about his ability to stick behind the dish, but his hit/power combination made him a first round talent. Moore turned in a .255/.414/.553 slash with more walks than strikeouts this season. He was a draft-eligible sophomore who turns 21 next week.
- The A’s went above slot to sign second-round pick Tommy White for $3MM, reports Robert Murray of FanSided (X link). The 40th pick comes with a value around $2.33MM. White’s bonus more closely aligned with the very end of the first round. An LSU product, the righty-hitting White had an OPS above 1.000 in all three college seasons. He hit .330/.401/.638 with 24 homers in his draft year. He has good contact skills and massive raw power, though there’s some concern about his aggressive approach. White played third base in college but isn’t a good athlete and could move to first base in pro ball. Oakland also went above slot with a $2MM bonus for third-rounder Gage Jump, Callis reports (X link). A teammate of White’s at LSU, Jump has a mid-90s fastball and a pair of breaking pitches. Most evaluators project him to the bullpen because of inconsistent control and his smaller stature.
- The Diamondbacks have agreements with supplemental picks Ryan Waldschmidt and J.D. Dix. Waldschmdit, a righty-hitting outfielder from the University of Kentucky, gets the $2.904MM value associated with the 31st pick. Law ranked him as the #11 player in the class, while FanGraphs and ESPN had him at the back of the top 20. Waldschmidt had a massive junior season, hitting .333/.469/.610. He’s limited to left field but draws praise for his plate discipline and exit velocities. Dix is a switch-hitting high school shortstop from Wisconsin. A Wake Forest commit, he has a well-rounded profile but underwent surgery on his throwing shoulder last fall and spent a chunk of this spring as a designated hitter.
- Yankees first-round pick Ben Hess agreed to terms at $2.7475MM, reports Bryan Hoch of MLB.com (on X). He was taken 26th overall, which comes with a slot value around $3.33MM. Hess is a 6’5 right-hander from the University of Alabama. He works in the mid-90s fastball and has a promising slider. Law ranked him 24th in the class and wrote that he has mid-rotation potential. Hess had a mixed track record in college and struggled to throw strikes in his draft year, though. He posted a 5.80 earned run average across 15 appearances this season. The Yanks went above slot in the second round for righty Bryce Cunningham, who signed for $2.2975MM. He had a 4.36 ERA over 16 starts this season for Vanderbilt. The 6’5″ hurler has a three-pitch mix and a chance to stick as a starter.
- The Phillies have a $2.5MM deal with first-rounder Dante Nori. He was selected with the 27th pick, which comes with a value around $3.23MM. Nori is a left-handed hitting outfielder from Michigan who’d been committed to Mississippi State. Evaluators praise his speed and nascent power potential. He’s significantly older than the typical high schooler, turning 20 not long after the draft.
- The Twins agreed to a $2.4MM bonus with 33rd pick Kyle DeBarge, Collazo reports (on X). Callis reports that Minnesota also went above slot to sign 69th pick Dasan Hill for $2MM. DeBarge is a 5’9″ shortstop from the University of Louisiana who hit .356/.418/.699 this season. He’s a hit over power player who could project to a utility role. Hill is a lanky left-hander from a Texas high school who had been committed to Dallas Baptist. FanGraphs had him as the #24 player in the class and projected him as a potential mid-rotation starter.
- 39th overall pick Caleb Lomavita signed with the Nationals. Mark Zuckerman of MASNsports.com reports (on X) that he landed a $2.325MM bonus that is just below slot value. Lomavita is a righty-hitting catcher out of Cal who has advanced contact skills and a good chance to stick behind the plate. His very aggressive offensive approach leads to some risk about his on-base floor. Lomavita hit .322/.395/.586 during his draft season but only walked 12 times in 55 games. The Nationals acquired the 39th pick from the Royals in the Hunter Harvey trade.
