D-Backs Notes: Del Castillo, Thomas, Rotation
The Diamondbacks are expected to begin the year without catcher/first baseman Adrian Del Castillo. Manager Torey Lovullo said Monday that the 26-year-old is dealing with a left calf injury that’ll keep him out of game action for the bulk of Spring Training (link via Alex Weiner of Arizona Sports). He’ll be reassessed closer to Opening Day but it seems unlikely he’ll get enough exhibition reps to avoid a season-opening injured list stay.
Del Castillo is third on the catching depth chart after Gabriel Moreno and James McCann. He nevertheless had a strong chance to win a bench job if healthy. Tyler Locklear will begin the season on the IL as he rehabs elbow and shoulder surgeries. The lefty-hitting Del Castillo has a fair bit of first base and designated hitter experience. Arizona doesn’t have a ton of position player depth on the 40-man roster, leaving a couple bench jobs up for grabs.
After an encouraging 25-game debut two years ago, Del Castillo struggled last season. He struck out 47 times in 131 plate appearances (a near-36% rate) while hitting .242/.290/.392 over 44 games. The Miami product has posted strong numbers throughout his minor league career, but they’ve always come with a concerning level of swing-and-miss. He’s a below-average defensive catcher, putting more pressure on the bat if most of his work comes in the first base/DH mix.
Pavin Smith and Carlos Santana are projected for a first base platoon. They’ll also get a decent number of DH reps, while Lovullo said Ketel Marte will log some time there in addition to his primary second base work. The D-Backs are reportedly poking around the trade market for a utility piece after they dealt Blaze Alexander to Baltimore for reliever Kade Strowd and a pair of minor leaguers. They’ll ideally find someone with more offensive punch than Tim Tawa and non-roster invitees Ildemaro Vargas and Jacob Amaya to play that role.
The bottom half of the lineup would be an even bigger concern if Corbin Carroll opens the season on the IL. Arizona’s star right fielder will miss most of Spring Training following last week’s hamate surgery. The hope is for Carroll to make it back by the beginning of the regular season. Fellow outfielder Alek Thomas tells Nick Piecoro of The Arizona Republic that he’s working mostly between left and center field with the expectation that Carroll will be in his typical position on Opening Day.
Thomas has played all three outfield positions in the minor leagues. He has played exclusively center field as a big leaguer, logging more than 3000 innings up the middle. Thomas is a quality defender who shouldn’t have any issue adjusting to a corner if the D-Backs need him to move around. Arizona is trying to get Jordan Lawlar acclimated to playing center field.
Lawlar has a higher offensive ceiling than Thomas has shown over 420 MLB contests, so the latter would be best suited for a fourth outfield role if everyone’s healthy. They’ll probably need both players in the starting lineup to begin the season, as Lourdes Gurriel Jr. will also open the year on the injured list after last summer’s ACL injury. Thomas could be a stopgap left fielder until Gurriel returns and/or prospect Ryan Waldschmidt plays his way to the big leagues.
There’s a fair bit of opportunity in one of the more top-heavy lineups in MLB. Carroll, Marte, Moreno and Geraldo Perdomo make for an excellent top half of a batting order. Nolan Arenado is on the downside of his career but should still be a solid everyday third baseman. The bottom third of the lineup and most of the bench is a lot less established.
It’s not quite as extreme on the pitching side, but there are some parallels. Free agent returnees Merrill Kelly and Zac Gallen are locked into the rotation; Lovullo has already named Kelly his Opening Day starter. Ryne Nelson figures to have a mid-rotation spot secure, but the Diamondbacks aren’t making any firm commitments beyond that.
“I can’t even really make comments about any projections or what the starting rotation is going to look like,” Lovullo told reporters (including Steve Gilbert of MLB.com). Right now, it looks as if Eduardo Rodriguez, Brandon Pfaadt and Michael Soroka are battling for two spots. Rodriguez and Soroka will be on the MLB roster, but Pfaadt has a pair of minor league options and could open the season in Triple-A. Soroka has the most experience of that group in a swing role and would be the most familiar with pitching in long relief if the D-Backs want all six pitchers on the active roster with a five-man rotation. One injury might take the decision out of Lovullo’s hands, but it’s another camp battle that Arizona fans will want to follow during exhibition play.
Diamondbacks Sign Sergio Alcántara, Place Ketel Marte On Restricted List Due To Personal Matter
The Diamondbacks announced a series of roster moves today, including the selection of right-hander Trevor Richards and the recall of catcher Adrian Del Castillo, moves which were reported earlier. They also signed infielder Sergio Alcántara to a major league deal. Right-hander Juan Morillo was optioned during the break, opening one active roster spot. Today, infielder Tristin English was optioned to the minors and second baseman Ketel Marte was placed on the restricted list. Marte opened one 40-man spot for Alcántara. To open another for Richards, catcher Gabriel Moreno was transferred to the 60-day injured list.
Per John Gambadoro of Arizona Sports 98.7 FM Phoenix, Marte is “taking some personal days.” Bob Nightengale of USA Today relays that Marte’s home was burglarized while he was away for the All-Star break. Perhaps Marte will be back in just a few days. Regardless, it’s less than ideal for the Diamondbacks, given that their season feels like it’s hanging by a thread at the moment.
The Snakes have been bit really hard by the injury bug this year. They have 11 pitchers on the injured list, many of whom won’t be returning this season due to significant surgeries. Naturally, that has impacted their ability to win ball games. They are currently 47-50 and 5.5 games back of a playoff spot. General manager Mike Hazen has said he would like the team to play its way into buyer position but it has felt like they might be drifting towards sell mode. Losing Marte for any amount of time doesn’t help, given that he’s one of the best all-around players in the game.
Blaze Alexander is perhaps the favorite to take over at the keystone in the interim but Alcántara will give them a fresh body on the roster. He got into one game with the Giants this year, going hitless in four at-bats. He has otherwise been in Triple-A, producing a tepid line of .206/.319/.252. He shouldn’t be expected to provide much with the bat but can play the three infield spots to the left of first base.
Moreno’s transfer to the 60-day IL is also less than ideal for the D’Backs. He was placed on the 10-day IL June 20th due to a hairline fracture in his right index finger. This transfer means the club doesn’t expect him to be able to return in the next month or so. They have been using José Herrera and James McCann behind the plate but will now go with a three-catcher setup. Del Castillo has great minor league numbers on a rate basis but has only played 14 Triple-A games this year due to injuries. He was reinstated from the minor league IL on July 1st.
Now that he’s healthy, perhaps he’ll get a chance to get some big league playing time while Moreno isn’t a near-term option. Del Castillo hit .313/.368/.525 in his major league debut last year. He’s hitting .288/.386/.559 in Triple-A this year but, as mentioned, in a fairly limited sample. Herrera’s line this year is just .197/.302/.268. McCann has a monster .375/.516/.708 line but in just nine games, as he was just added to the roster recently. He slashed .224/.279/.352 over the previous four seasons.

Diamondbacks To Select Trevor Richards
The Diamondbacks are selecting the contract of right-hander Trevor Richards from Triple-A Reno, reports John Gambadoro of 98.7 Arizona Sports. Alex Weiner of AZSports.com noted yesterday that Richards had a locker set up in the big league clubhouse during yesterday’s optional team workout at Chase Field. Catcher Adrian Del Castillo is also being recalled from Reno. Gambadoro adds that third baseman Eugenio Suárez, who had an injury scare when he was plunked on the hand in Tuesday’s All-Star Game, will be in tonight’s lineup for the D-backs.
Richards is now with his third organization of the season, having also spent time with the Royals and Cubs. He tossed three big league innings with Kansas City but was tagged for four runs in that small sample. That’s his only big league time this year. He’s spent the rest of the season between the Triple-A affiliates for those three clubs, pitching to a collective 5.12 ERA with a 22% strikeout rate and 10.6% walk rate.
The 32-year-old Richards has pitched in each of the past eight major league seasons, though he hasn’t had much success since 2021. He sports a 5.05 ERA in 205 innings dating back to Opening Day 2022. He’s set down 28.2% of his opponents on strikes in that time but has also issued walks to 12% of the hitters he’s faced and surrendered an average of 1.27 homers per nine innings pitched.
Arizona’s bullpen has been decimated by injury. A.J. Puk and Justin Martinez both underwent UCL surgeries last month. Jalen Beeks is out with a lower back issue, and Ryan Thompson hit the 15-day IL due to a shoulder injury a couple weeks back. Shelby Miller is on the 15-day IL due to a forearm strain.
Richards doesn’t have a strong recent track record, but he’s bee a serviceable middle reliever at various points in his career and at the very least can miss bats at a solid clip. His above-average changeup makes him a quality option against lefties — more so than versus righties — which probably holds extra appeal to the D-backs with both Puk and Beeks out of action. Andrew Saalfrank and 27-year-old rookie Kyle Backhus are the only lefties in manager Torey Lovullo’s bullpen and the only healthy left-handed relievers on the 40-man roster at the moment, so adding a righty who has a nice track record against southpaws makes some sense.
As for Del Castillo, it’s not yet clear what sort of corresponding move there is with regard to the catching corps. He’d be an upgrade offensively over Jose Herrera, who has been sharing catching duties with veteran James McCann while Gabriel Moreno‘s broken finger heals. Neither Herrera nor McCann can be optioned — Herrera because he’s out of minor league options and McCann because players with five-plus year of MLB service cannot be sent down without their consent. McCann has more than 10 years of major league service time.
The 25-year-old Del Castillo made his MLB debut last year and hit .313/.368/.525 with four homers in 87 plate appearances. He’s slashing .288/.386/.559 in 70 plate appearances but has spent the bulk of the season on the minor league injured list. Herrera (.197/.302/.268) has struggled greatly at the plate but is a better defensive option. McCann has just 31 plate appearances since signing in the wake of that Moreno injury but has gone 9-for-24 with a pair of homers and a pair of doubles (.375/.516/.708).
A.J. Puk Undergoes Elbow Surgery; Gabriel Moreno Diagnosed With Fractured Finger
June 21: MLB.com’s Steve Gilbert reports that A.J. Puk underwent internal brace surgery and not a Tommy John procedure. Tommy Henry, however, will require Tommy John. Gilbert adds that Justin Martinez, another D-backs pitcher in need of Tommy John surgery, will have his operation performed next week.
June 20: Diamondbacks reliever A.J. Puk underwent elbow surgery today, manager Torey Lovullo tells the Burns & Gambo show. Puk had visited Dr. Neal ElAttrache after experiencing recurring soreness as he tried to work back from a flexor strain. Lovullo didn’t have specific details as to whether he required a full Tommy John ligament replacement or some kind of modified internal brace procedure. Puk’s season is over in either case. He’s likely to miss most or all of 2026 as well.
Additionally, the manager told Burns & Gambo that catcher Gabriel Moreno has a hairline fracture in his right index finger. The D-Backs placed Moreno on the 10-day injured list yesterday but had initially called it a hand contusion. He has evidently been playing through an undiagnosed fracture for some time. A return timetable is unclear but will be measured in “weeks, not days.” Topping it all off, Nick Piecoro of The Arizona Republic reports that left-hander Tommy Henry is also headed for season-ending elbow surgery.
The news on Puk is terrible but unsurprising. He has been plagued by elbow issues for the past two months. He’d undergone Tommy John surgery once before in his career. The 6’7″ southpaw required the procedure in 2018 when he was a member of the A’s farm system. He missed that season and was limited to 28 combined appearances between the minors and MLB the following year.
Acquired from the Marlins at the 2024 deadline, Puk has been one of the most dominant relievers in the sport since getting to Arizona. He recorded 43 strikeouts in 27 1/3 innings after the trade last summer, working to a 1.32 ERA in the process. He had fanned 12 more hitters against two walks while collecting four saves in his first eight appearances this year. Aside from a terrible stint in Miami’s rotation early last season, he has been generally excellent since the A’s traded him to Miami over the 2022-23 offseason.
Depending on the nature of the surgery, there’s a decent chance this will end his time with the D-Backs. Puk has over five years of MLB service. He’ll be eligible for arbitration for the final time next offseason. He’d earn only a modest raise on this year’s $2.95MM salary, but a full ligament repair would make him a non-tender candidate. Players usually require 14-plus months to return from Tommy John surgery, and that would be Puk’s second such procedure. He’s likely to be out through next year’s All-Star Break even if he “only” needed the internal brace procedure, though the D-Backs would happily retain Puk for around $3MM if they felt they could get half the season from him.
The news on Puk comes a week after the news that Justin Martinez, the team’s other top reliever, also needs to go under the knife. Corbin Burnes and Jordan Montgomery have been Tommy John victims in the rotation. It’s difficult for any team to weather that kind of injury luck. Arizona has hovered around .500 despite having an elite offense because of their issues on the mound.
They’ll lose Moreno from that lineup for what seems like a decent chunk of time. There’s a significant drop off to light-hitting backup Jose Herrera. The Snakes selected Aramis Garcia to work off the bench behind Herrera. Adrian Del Castillo is the only other catcher on the 40-man roster. He’s a far better hitter than either Herrera or Garcia but isn’t regarded as a great defender. Del Castillo won’t be an option in the immediate future regardless, as he landed on the Triple-A injured list today with what is expected to be a minor back injury. Moreno will be the clear starting catcher once he’s healthy, but his injury could lead the Snakes to pursue a veteran #2 who can provide more punch than Herrera offers.
Henry, 27, is a former second-round pick who has a 5.07 ERA over 37 career appearances. He has an ERA above 8.00 over 11 starts in Triple-A Reno this year. This is his final minor league option season and he seems unlikely to stick on the 40-man roster throughout the offseason. His elbow injury occurred in Triple-A, so he’s on the minor league injured list. He’ll continue to count against the 40-man for now. The D-Backs may place him on the MLB 60-day IL or simply decide to release him (which would save them a bit of money relative to putting him on the MLB injured list) once they need another roster spot.
Diamondbacks Outright Rene Pinto
Catcher Rene Pinto has cleared waivers and been assigned outright to Triple-A Reno by the Diamondbacks, according to Alex Weiner of AZ Sports. Pinto does not have the requisite service time or previous outright necessary to reject the assignment, so he’ll remain in the organization as non-roster depth going forward.
Pinto entered camp with Arizona in the mix to back up Gabriel Moreno alongside Adrian Del Castillo and Jose Herrera. The job ultimately went to Herrera, which necessitated the club designating Pinto for assignment as he had no minor league options remaining. The 28-year-old signed with the Rays out of Venezuela as an amateur and made his pro debut back in 2014. He’s spent his entire pro career in a Rays uniform prior to this winter, when the Rays DFA’d him in November and he was claimed off waivers by the Orioles. He stuck with Baltimore throughout much of the offseason but was DFA’d once again to make room for Charlie Morton on the club’s 40-man roster, at which point he was claimed by Arizona.
Pinto made his big league debut with the Rays back in 2022. The cup of coffee lasted only 25 games, and he hit just .213/.241/.325 during that time. Despite that meager performance in the majors, however, Pinto turned in a strong season at Triple-A as he slashed a strong .266/.320/.521 across 73 games at the level. That was enough to earn Pinto additional opportunities in Tampa, and he generally performed much better in them. 2023 saw Pinto appear in 38 games in the majors, hitting a respectable .252/.267/.456 with six homers in just 103 trips to the plate.
That intriguing combination of power and strong defense behind the plate was enough to make the Rays comfortable making Pinto their starting catcher to open the 2024 season. Unfortunately, Pinto didn’t last very long in the role. While he hit a respectable .214/.292/.429 that clocked in above league average over 19 games, those would be the only 19 games Pinto would play in the majors last year as he ceded playing time to a tandem of Ben Rortvedt and Alex Jackson. The catcher didn’t exactly go on to make a case for himself to get another shot in the majors upon being optioned to Triple-A, either, hitting just .191/.257/.373 in 53 games for the club’s Durham affiliate.
Now that Pinto has cleared waivers and been outrighted to the minors, he likely stands as the next man up to help out behind the plate in the event of an injury to either Moreno or Herrera. Normally, that role would appear more likely to go to Del Castillo given that he remains on the 40-man roster while Pinto does not, Weiner notes that Del Castillo has been placed on the minor league’s 7-day injured list. It’s unclear what ailment is bothering Del Castillo or how long he’ll be out of action at this point, but until he returns he won’t be able to serve as a fill-in catcher in the majors fro the Diamondbacks.
Diamondbacks Select Adrian Del Castillo
2:30pm: The Diamondbacks have officially announced these moves and others. Del Castillo has been selected and Moreno has been placed on the IL with a strained left adductor. They also reinstated left-hander Eduardo Rodríguez from the 60-day IL, a move that was reported last week. To activate Rodriguez, the club optioned right-hander Humberto Castellanos and transferred righty Bryce Jarvis to the 60-day IL. It was also reported last week that Jarvis is unlikely to return this year due to his sprained right elbow.
12:40pm: The Diamondbacks are going to place catcher Gabriel Moreno on the 10-day injured list with a groin injury, per John Gambadoro of Arizona Sports 98.7 FM on X. Fellow backstop Adrian Del Castillo will have his contract selected to take Moreno’s place on the roster. The Snakes already had a 40-man vacancy so no further moves will be required.
Moreno came up limping during yesterday’s game while trying to run out a ground ball. He was removed from the contest with what the team described as a strained left groin. It’s still unclear how long he is expected to be out of action but it’s a rough blow for the Diamondbacks regardless. Moreno is slashing .262/.344/.385 this year for a 107 wRC+ with strong defensive grades as well. FanGraphs considers him to have been worth 2.4 wins above replacement in 86 games.
It’s the second IL stint of the year for Moreno, who also missed some time at the end of June due to a sprained left thumb. Prior to that, he had been sharing the catching duties with Tucker Barnhart, with José Herrera called up to pair with Barnhart in Moreno’s absence. Once Moreno was ready to return in early July, the club decided to keep Herrera around, with Barnhart designated for assignment and eventually released.
That left the Diamondbacks with Moreno and Herrera as the only two backstops on the 40-man roster. Now that Moreno is heading to the IL again, they need to reach into their non-roster depth, which gets Del Castillo up to the majors for the first time.
Now 24 years old, Del Castillo was selected with a competitive balance pick in 2021, going 67th overall in that year’s draft. Baseball America ranked him #29 in Arizona’s system coming into this year but he has launched himself up to #16 in their most recent update. He was #36 at FanGraphs earlier in the year.
BA considers him subpar defensively but strong at the plate, which has shown up at times during his minor league career. That’s especially true here in 2024, which is likely why he earned such a notable bump in the BA rankings. In 100 Triple-A games this year, he has 24 home runs, an 11.5% walk rate and a 16.8% strikeout rate. His .319/.403/.608 batting line translates into a 143 wRC+ even in the hitter-friendly environs of the Pacific Coast League.
If he can bring even a small portion of that production up to the big leagues with him, it will go a long way towards compensating for the loss of Moreno. Herrera has hit just .229/.308/.286 this year for a 72 wRC+ with his glovework graded as near league average. Perhaps Del Castillo can outperform him at the plate but even top prospects can struggle when first exposed to the majors. The club will also have to consider that Herrera has a head start on Del Castillo in terms of building relationships with the pitching staff.
The Snakes are currently 61-52 and essentially in a three-way tie for the National League Wild Card spots with Atlanta and San Diego. Atlanta is 60-51 and percentage points ahead of the two other clubs, who are each 61-52. The Mets are just 1.5 games back of that group and five other clubs are just behind New York. With that crowded playoff race, the importance of every game will be magnified going forward. The catching situation will likely evolve in the coming weeks, depending on how much time Moreno needs to miss and how Del Castillo performs in his first taste of the majors. Herrera is in his final option year and will be out of options in 2025.
