Diamondbacks Place Lourdes Gurriel Jr. On 10-Day IL, Select Tommy Troy
8:35 pm: Manager Torey Lovullo says that Gurriel’s hamstring injury is minor, according to Nick Piecoro of the Arizona Republic. The hope is he’ll be back from the IL as soon as he’s eligible.
5:59 pm: The Diamondbacks are placing Lourdes Gurriel Jr. on the 10-day injured list with a strained left hamstring, as reported by Alex Weiner of Arizona Sports. The club is also selecting the contract of prospect Tommy Troy. Arizona’s 40-man roster was at 39, so no corresponding move is needed for Troy.
Gurriel, 32, is in the midst of his worst big-league season. He had a delayed start while finishing his recovery from right ACL surgery. Since debuting on April 18th, Gurriel has a line of .228/.284/.304 with a single home run. That’s good for just a 66 wRC+, indicating Gurriel is 34% worse than the average hitter. Granted, he’s only made 102 plate appearances, but Gurriel showed diminished offense last year as well. He had a 95 wRC+ in 129 games while posting an 87.8 MPH average exit velocity, down from 88.4 MPH in 2024. This year, Gurriel’s exit velo is sitting at 87.5 MPH.
Arizona has a 99 wRC+ as a team, which speaks to its top-heavy offense. Corbin Carroll (161 wRC+), Ildemaro Vargas (136), and Nolan Arenado (132) are all hitting very well. Geraldo Perdomo and Ketel Marte are right around league average. In contrast, Gurriel has been one of the team’s worst regulars this year, and since he’s not a good defender, he’s not doing enough to make up for the lack of hitting. Gurriel’s return timeline depends on the severity of the hamstring strain, which could be made clearer in the coming days.
In the meantime, Arizona’s offense could be jolted by Troy, who will be making his major league debut when he gets into a game. Troy was the club’s first-round draft pick in 2023 and rates as their No. 4 prospect according to MLB.com. He reached Triple-A last year at the age of 23 and held his own, batting .295/.381/.429 in 182 plate appearances. Troy has improved to .307/.397/.449 in 205 plate appearances this year, good for a 109 wRC+. His strikeout rate has jumped back to 24.4% after sitting at 16.9% in 2025, but otherwise, there’s plenty to like in Troy’s profile.
Troy came up as a middle infielder but has played 219 innings in the outfield this year, compared to 162 at the keystone. That shift is a testament to Troy’s speed, which is seen as his best tool and allowed him to steal 40 bases from 2024-25. The presence of Perdomo and Marte on the big league roster blocks Troy from his natural positions, so his long-term future with Arizona could be in the outfield. Indeed, this promotion could be seen as a trial run of Troy’s outfield defense while Gurriel is on the IL.
Whether Troy sticks in the Majors this time around also depends on his hitting. Despite Gurriel’s poor performance this year, he has enough of a track record as an average hitter to slide back into left when he returns. Tim Tawa and Jorge Barrosa are both on the roster as backup outfielders, though neither has shown much with the bat in the Majors. That said, Barrosa is out of options whereas Tawa has two option years remaining. If Troy hits enough to stick around, he has the defensive experience to serve as a utility man, with Tawa potentially being optioned in his place.

Diamondbacks Release Joe Ross
The D-backs released veteran right-hander Joe Ross, who’d been pitching with their Triple-A affiliate in Reno, per the MiLB.com transaction log.
Ross signed a minor league deal with the Snakes over the winter and cracked the Opening Day roster. He pitched only 3 2/3 innings before being designated for assignment, at which point he cleared waivers, elected free agency and returned to the organization on a new minor league contract. He’s been pitching with Reno since.
It’s been a decent year for Ross with the D-backs’ top affiliate. He’s tossed 21 innings, working mostly in long relief, and posted a 4.29 earned run average in that hitter-friendly setting. The 32-year-old (33 tomorrow) has just a 14% strikeout rate on the year, but he’s offset that lack of whiffs with a 5.8% walk rate, a 47.8% grounder rate and plenty of light contact (87.7 mph average exit velocity, 38% hard-hit rate).
Ross has pitched in parts of nine big league seasons and sits just one day shy of eight years of major league service. He showed glimpses of breaking out as a quality big league starter early in his career, but much like his older brother (Tyson Ross) was routinely set back by injuries. He’s had a pair of Tommy John surgeries in his career in addition to a procedure to remove bone spurs from his elbow. Ross has also had multiple IL stints due to lower back injuries and shoulder troubles.
Ross had a nice season with the ’24 Brewers, tossing 74 innings with a 3.77 ERA and rate stats that were only slightly worse than league average. He was hit hard in a partial season with the ’25 Phillies though, yielding a 5.12 ERA with a career-low 17.1% strikeout rate. Overall, the big 6’4″ righty has a 4.37 ERA, 20.6% strikeout rate, 7.7% walk rate and 43% ground-ball rate in 572 major league frames.
Teams in need of some length in the bullpen and/or rotation depth could take a minimal-risk flier on Ross now that he’s a free agent again. He’s stretched out enough for a swingman role right now and could be built up to a starter’s workload without much issue; Ross has a pair of three-inning outings on the books already, the most recent coming early this month. He’s been sitting 95.6 mph with his four-seamer and 96.2 mph with his sinker in Reno. Both would be career-best marks.
Diamondbacks Place James McCann On IL, Select Aramis Garcia
The Diamondbacks announced that catcher James McCann has been placed on the 10-day injured list with a strained right quad. Fellow catcher Aramis Garcia has been selected to take his place on the roster. The Snakes had a couple of 40-man vacancies, with Garcia filling one of them.
McCann, 36 next month, was signed to a $2.75MM deal to serve as a veteran backup to Gabriel Moreno. McCann has appeared in 22 games with a .203/.217/.254 line and questionable defensive metrics.
Arizona has been rostering three catchers for most of the season. Adrian Del Castillo has done some catching but has been seeing a lot of time in the designated hitter slot, even though he hasn’t been living up to that designation, with a .185/.232/.326 line and 33.3% strikeout rate this year.
It seems the Snakes prefer to keep that three-catcher system going. Earlier this year, when Moreno required a stint on the IL, they added Garcia to the roster. He was mostly there for emergencies, as he spent over two weeks on the roster but only made three plate appearances. When Moreno came off the IL, the out-of-options Garcia was designated for assignment and outrighted back to Triple-A Reno.
It’s possible Garcia is slated for a similar experience now. While McCann is out, the Snakes will continue to have Moreno as their primary catcher, with Del Castillo a backup/DH. Garcia will be there for late-game substitutions or if someone gets hurt. Garcia has just a .210/.245/.321 line in his career but the Diamondbacks obviously value his defense and/or the work he does with pitchers. He was selected to their roster twice last year and this is now already his second selection of 2026.

D-Backs Trade Alek Thomas To Dodgers
The Diamondbacks and Dodgers announced a trade sending center fielder Alek Thomas to L.A. for minor league outfielder Jose Requena. The Dodgers will assume the approximate $1.4MM remaining on Thomas’ $1.9625MM arbitration salary. He’ll reportedly be optioned to Triple-A Oklahoma City, while the Dodgers designated fellow outfielder Michael Siani for assignment last night to open a 40-man roster spot.
Arizona designated Thomas for assignment last week when they called up top outfield prospect Ryan Waldschmidt. The Dodgers take a flier on the 26-year-old, a former second-round pick who was one of the better prospects in MLB when he debuted in 2022. He’s a highly-regarded center fielder who had hit at every stop in his minor league career. That hasn’t carried over against MLB pitching, as Thomas has been a well below-average hitter over his four-plus seasons in the big leagues.
Thomas is an extremely aggressive hitter, ranking in the top 15 this season in both overall swing rate and chases off the plate. He has particularly struggled against secondary stuff as a result, and the very low walk rates have consistently tamped down his on-base percentage. Thomas has a career .230/.273/.361 batting line in just shy of 1500 plate appearances. It’s the ninth-lowest OBP among hitters who have tallied at least 1000 trips since the start of the ’22 season.
While he hasn’t developed offensively, Thomas has a strong reputation with the glove. His sprint speed and defensive grades have dipped slightly since he suffered a left hamstring strain early in 2024, but he still rates as an above-average defender and baserunner.
The D-Backs have considered trades of both Thomas and Jake McCarthy for a few seasons. They’re now both gone to division rivals, as they shipped McCarthy to Colorado over the offseason. Waldschmidt and Jorge Barrosa are manning center field between Corbin Carroll and Lourdes Gurriel Jr.
Thomas still has a minor league option remaining, so he’ll begin his time in the L.A. organization in Triple-A. The Dodgers are operating without a true backup center fielder behind Andy Pages, but they can’t option Santiago Espinal or Miguel Rojas. Although fourth outfielder Alex Call is a better fit in a corner spot and has a couple options remaining, he’s hitting well in a limited role as a right-handed platoon player. The Dodgers should also get Kiké Hernández back from the injured list two weeks from now.
The Dodgers spend a couple million dollars to swap in Thomas for Siani as a fifth outfielder. In addition to the salary obligations, they’ll also pay just over $1.5MM in luxury tax commitments. That’s of little concern for the Dodgers, who can retain Thomas via arbitration for at least two more seasons. He needs to spend another 20 days on the MLB roster in 2026 to surpass four years of service time, which would keep him on track for free agency after the ’28 campaign. If he spends at least 20 days in the minors, he’ll be out of options next year.
Siani is also a speed and defense center fielder. He bounced around the league via waivers over the offseason, twice being claimed by the Dodgers. He has been on optional assignment all season, batting .225/.355/.303 without a home run while striking out 30 times in 107 plate appearances in Oklahoma City. He’s also in his final option year and will be traded or placed back on waivers within the next five days.
Requena is a 17-year-old who hasn’t played a professional game. Listed at 6’3″ and close to 230 pounds, he’s a right-handed hitter who signed as an amateur out of Venezuela in January. Ben Badler of Baseball America unsurprisingly wrote at the time that Requena is a corner outfielder whose profile is built on raw power and plus arm strength. He’ll likely make his professional debut in the Dominican Summer League.
MLBTR’s Steve Adams first reported that Thomas was being traded to the Dodgers. Francys Romero confirmed that Requena was the return. Nick Piecoro of The Arizona Republic reported that the Dodgers were assuming Thomas’ salary, while Jack Harris of The California Post confirmed he’d be optioned to Triple-A. Image courtesy of Mark J.

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.
Diamondbacks Outright Aramis Garcia, Jesus Valdez
The Diamondbacks announced that they have outrighted catcher Aramis Garcia to Triple-A Reno and infielder Jesus Valdez to Double-A Amarillo. Garcia had been designated for assignment last week when Gabriel Moreno was activated from the 10-day injured list. There wasn’t any previous indication that Valdez had been removed from the 40-man roster. Arizona’s count on that 40-man is now down to 38.
Garcia, 33, is a veteran depth catcher who is out of options. He is a competent defender but is has hit just .210/.245/.321 in his career. That has put him in position to bounce on and off the Arizona roster with regularity. He signed a minor league deal with the Snakes ahead of the 2025 season. Last year, he was twice added to the big league roster. In both cases, he was designated for assignment a few days later and sent back to Reno after passing through waivers.
It’s possible the same sequence of events plays out this year. Garcia was called up to the big leagues to cover for Moreno’s injury and then was bumped off when Moreno was reinstated. Garcia has the right to elect free agency but might be comfortable sticking with the Aces and waiting for the next catching injury to pop up.
The Valdez outright might be a more unique situation. The 28-year-old was just added to the club’s roster a little over a week ago. The Diamondbacks and Padres were playing in Mexico City and were allowed a 27th man on the roster. Valdez was added to fill that extra bench spot for the Diamondbacks, getting called up from Double-A Amarillo. He didn’t appear in either of the Mexico City games and was optioned back to the Sod Poodles right after that series.
It appears that the Diamondbacks quietly put him on waivers and no one claimed him. That’s not especially surprising since Valdez hasn’t really been a notable prospect in his career and is a 28-year-old playing in Double-A, though he does have some Triple-A experience. Dating back to the start of 2021, he has a combined .241/.292/.401 line and 76 wRC+ in the minor leagues.

D-backs Designate Aramis Garcia For Assignment
The Diamondbacks announced this morning that they’ve designated catcher Aramis Garcia for assignment and reinstated fellow backstop Gabriel Moreno from the 10-day injured list. Additionally, the Snakes recalled lefty Brandyn Garcia from Triple-A Reno and optioned lefty Philip Abner in his place.
Aramis Garcia, 33, signed a minor league deal with the Snakes in the offseason. He started the year as Triple-A depth, as Arizona deployed a catching tandem of Moreno and James McCann. The season began with Adrian Del Castillo on the injured list with a calf strain but he was activated after a minimal stint. Injuries to Pavin Smith and Carlos Santana opened up the designated hitter spot and allowed the Diamondbacks to roll with three catchers, with Del Castillo getting a decent amount of DH time.
Moreno suffered an oblique strain in mid-April. Arizona could have continued with McCann and Del Castillo as the catching duo but they decided to add Garcia, keeping them at three backstops and giving them more freedom to keep Del Castillo in the DH mix. That didn’t leave a lot of playing time available for Garcia. He’s been on the roster for over two weeks and only appeared in three games, making three plate appearances. He went one for three with a single and a strikeout.
Del Castillo has options and could have been sent down today, especially since he’s hitting .207/.246/.362 so far this year, but the Diamondbacks have decided to keep him in the mix. He is much better against righties, so perhaps Moreno’s return will allow him to be deployed situationally instead of behind the plate.
Garcia is out of options, so he had to be bumped into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Diamondbacks could take five days to field trade interest, though they could also put him on waivers at any time before that. Garcia is probably not likely to garner too much interest. Given his out-of-options status, another club would have to be willing to plug him directly onto the big league roster.
He’s never been much more than a part-time catcher, as his career high for games in a season is 47. Over multiple seasons, he has appeared in 124 contests with a .210/.245/.321 line in 334 plate appearances. He’s a solid defender and framer but the bat is light and the lack of roster flexibility hurts him.
He has previously been outrighted in his career, which means he would have the right to elect free agency if he is passed through outright waivers again. Twice last year, he briefly joined the Arizona roster and then got bumped off, eventually ending up back in Reno. It seems the most likely scenario is that he clears waivers and then either accepts an assignment with the Aces or elects free agency and then re-signs on a new minor league deal.

Diamondbacks Select Jesus Valdez
The Diamondbacks have selected infielder Jesus Valdez to the big league roster, per a team announcement. He’s been optioned to Double-A. Valdez will serve as the club’s 27th man for today’s game against the Padres. If he makes it into the game, it will be his big-league debut.
Arizona and San Diego were permitted to add an extra man for the Mexico City series, but it had to be a position player. After initially declining to make an addition to the roster, the Diamondbacks made the move for the second game of the series. An injury to shortstop Geraldo Perdomo led to the decision, per Nick Piecoro of the Arizona Republic. Perdomo went down with an ankle injury yesterday. The issue isn’t expected to require an IL stint, Piecoro relayed in a separate post.
Valdez was signed by the Dodgers out of the Dominican Republic in 2017. He was dealt to the Pirates the following year for David Freese. The infielder had some offensive success in the lower levels of the minors, but was released by Double-A Altoona after a brief stint in 2021. He latched on with the Diamondbacks on a minor league agreement in 2022.
The 28-year-old Valdez has posted modest numbers in the upper levels of Arizona’s system. He has an identical .706 OPS for his career at Double-A (116 games) and Triple-A (47 games). Valdez has scuffled to a .211/.375/.263 line in seven minor league games this year.

D-Backs Release Shawn Dubin
The Diamondbacks released reliever Shawn Dubin from his minor league deal, according to the MiLB.com transaction log. Arizona also re-signed first baseman Luken Baker on a new minor league contract. Baker had briefly elected free agency after being outrighted on Monday but will return to Triple-A Reno.
Dubin joined the Snakes on a non-roster invite over the offseason. He made five spring appearances and pitched twice for Reno within the first few days of the regular season. Dubin surrendered four runs on five hits and a walk over two innings and was quickly transferred to the development list. That’s generally to afford non-injured minor league players time to make mechanical adjustments outside of game action.
The righty didn’t wind up returning to Reno’s active roster. He’ll now seek an opportunity elsewhere, likely on another minor league contract. Dubin has spent a good chunk of the past two seasons in the big leagues. He pitched a career-high 45 1/3 innings for the Astros in 2024. The former 13th-rounder split last year between Houston and Baltimore, allowing a 5.08 earned run average through 33 2/3 frames. He has a 4.81 ERA with a nearly league average 22.3% strikeout percentage over 88 MLB innings.
Baker is back in the Reno lineup tonight. The righty batter played in nine games for the Aces early in the season, batting .242 with a homer. He was called up when Carlos Santana went down with an injury and held a bench spot for a couple weeks. Arizona designated him for assignment last weekend once Lourdes Gurriel Jr. returned from the injured list.
The Diamondbacks have gotten surprisingly strong production out of Ildemaro Vargas and rookie Jose Fernandez between first base and designated hitter. Arizona first basemen have hit .305/.317/.492 in 60 plate appearances since the Santana injury. Vargas is a light-hitting utilityman, while Fernandez is a mid-tier prospect who’d played one Triple-A game before being pressed into action. They’re probably not going to continue hitting at this rate, but it has been a nice boost from lineup spots that could’ve been zeros after injuries to Santana, Pavin Smith, and Tyler Locklear.
