Diamondbacks' Adrian Del Castillo: Begins rehab assignment
Rotowire
Del Castillo (calf) started at catcher and went 0-for-4 with a walk and a run scored in a rehab game for Triple-A Reno on Tuesday.
Del Castillo began a rehab assignment Tuesday and will continue it Wednesday, when he's scheduled to serve as the designated hitter for the Aces, per Alex Weiner of Arizona Sports. He was placed on the 10-day injured list March 22, so he could be activated soon if the back-to-back rehab games go well. As a left-handed bat, Del Castillo is an ideal replacement for Pavin Smith (elbow), who landed on the 10-day injured list earlier this week.

Diamondbacks' Adrian Del Castillo: Beginning rehab assignment
Rotowire
Del Castillo (calf) will begin a rehab assignment with Triple-A Albuquerque on Tuesday, Aaron Hughes of SI.com reports.
Del Castillo missed the entirety of Cactus League play with a strained left calf, so this is a big step in his recovery to see some game action. Del Castillo appeared in 44 regular-season games with the Diamondbacks last season and slashed .242/.290/.392 with four home runs, 17 RBI, nine runs scored and an 8:47 BB:K across 131 plate appearances.

Diamondbacks' Adrian Del Castillo: Moves to IL
Rotowire
The Diamondbacks placed Del Castillo on the 10-day injured list Wednesday due to a left calf strain.
Del Castillo was unable to make any Cactus League appearances after straining his left calf shortly before the start of camp, but he made enough progress in his recovery for Arizona to clear him to serve as a designated hitter in a minor-league spring training game earlier this week, per MLB.com. Arizona will likely want Del Castillo to be available to play catcher prior to activating him from the IL, and it's unclear how close the 26-year-old might be to taking part in defensive drills.

Diamondbacks' Adrian Del Castillo: Begins running
Rotowire
Del Castillo (calf) is continuing to rehab and has begun running, Alex Weiner of Arizona Sports reports.
Del Castillo will operate as a designated hitter in minor-league games before the organization makes its next move. It's unclear what the Diamondbacks have in mind once Del Castillo is ready to play. He could serve as a third catcher and part-time DH in the majors or head back to the minors where he can continue to develop defensively.

Diamondbacks' Adrian Del Castillo: Begins baseball activties

Del Castillo (calf) has begun hitting in cages and catching bullpen sessions, Alex Weiner of Arizona Sports reports.

Diamondbacks' Adrian Del Castillo: Status in doubt for Opening Day
Rotowire
Del Castillo said Monday that he expects to be sidelined for around one month due to his left calf injury, Nick Piecoro of The Arizona Republic reports.
While Del Castillo is hopeful that he'll be able to play in at least one Cactus League game or exhibition before the beginning of the regular season, the extended time he'll miss this spring could end up costing him a spot on the Opening Day roster. Arizona is expected to head into the season with Gabriel Moreno and James McCann as its top two catchers, so Del Castillo would merely provide a third option at the position and would likely see most of his playing time at designated hitter. Because the 26-year-old still has a pair of minor-league options remaining, the Diamondbacks may prefer to option Del Castillo to Triple-A Reno, which would allow him to play on a more regular basis once he overcomes the calf issue.

Diamondbacks' Adrian Del Castillo: Nursing calf issue
Rotowire
Del Castillo is dealing with a left calf issue, Alex Weiner of Arizona Sports reports.
He's been working off to the side since reporting to camp earlier this week. Arizona manager Torey Lovullo said Del Castillo will be brought along slowly this spring, but it's unclear how long that period might last. The 26-year-old's bat is seen as an asset and more developed than his defense, and while there are no plans to move Del Castillo out from behind the plate, he's third on the depth chart and likely to see more time at DH than catcher in 2026.

Rotowire
Del Castillo hit a two-run home run in his lone at-bat in Tuesday's 5-4 win over the Dodgers.
Del Castillo contributed to the Diamondbacks' comeback effort with a seventh-inning blast to pull them within a run. This was his second homer in his last five games, though he's mostly been limited to bench duties recently.

Diamondbacks' Adrian Del Castillo: Idle against right-hander
Rotowire
Del Castillo is out of the lineup for Sunday's game against the Red Sox.
Del Castillo had started in each of the Diamondbacks' previous three matchups with right-handed pitchers, but he'll hit the bench Sunday against the Red Sox's Brayan Bello. With Del Castillo taking a seat, Ketel Marte will serve as Arizona's designated hitter, which opens up a spot in the infield for Jordan Lawlar.

Diamondbacks' Adrian Del Castillo: On bench against southpaw
Rotowire
Del Castillo is out of the lineup for Wednesday's game against the Guardians.
Though his absence from the lineup against a left-handed starter (Parker Messick) doesn't come as a surprise, the left-handed-hitting Del Castillo was on the bench for two matchups against right-handed starters over the Diamondbacks' previous three contests. Del Castillo has slashed an underwhelming .232/.270/.391 with a 32.4 percent strikeout rate over 74 plate appearances since being called up from Triple-A Reno coming out of the All-Star break, and until he picks up the pace at the dish, he might have to settle for more of a part-time role.

Del Castillo started in seven of the past eight games while going 8-for-29 (.276 average) with two home runs, four doubles, seven RBI and three runs.

Diamondbacks' Adrian Del Castillo: Blasts second homer
Rotowire
Del Castillo went 2-for-4 with a double, a home run and three RBI in Saturday's loss to Colorado.
Del Castillo made the most of his opportunities at altitude, notching his second three-RBI performance in the last week. The catcher has appeared in 20 games since being called up after the All-Star break, seeing most of his action at DH and batting .239 (16-for-67) with two homers and 10 RBI.

Diamondbacks' Adrian Del Castillo: Maintains presence against RHP
Rotowire
Del Castillo started at designated hitter and went 1-for-4 in Sunday's 6-0 loss to the Pirates.
Del Castillo continued to be a lineup regular at DH against right-handed starters (Paul Skenes on Sunday). He doesn't have one plate appearance against a southpaw. His playing time could take a hit when Pavin Smith (oblique) returns, but a healthy Smith might be needed to handle first base. Additionally, the Diamondbacks are clearly sellers heading into the trade deadline, which suggests the organization may give developmental plate appearances to prospects like Del Castillo over the final two months.

Diamondbacks' Adrian Del Castillo: Ready for rehab assignment
Rotowire
Del Castillo (back) has been sent to the rookie-level Arizona Complex League Diamondbacks to begin a rehab assignment, Alex Weiner of ArizonaSports.com reports.
Del Castillo landed on the 7-day injured list at Triple-A Reno a week ago with a lower-back injury. He had previously missed time with a right shoulder injury and only recently was allowed to resume defensive duties. If Del Castillo can bounce back quickly from the back issue and catch without any restrictions, he could get another look for a Diamondbacks club that's missing Gabriel Moreno (hand).

Diamondbacks' Adrian Del Castillo: Begins rehab assignment
Rotowire
Del Castillo (shoulder) served as the designated hitter and went 1-for-3 with a walk and two runs scored for the ACL Diamondbacks on Tuesday.
Del Castillo began a rehab assignment in the Arizona Complex League as he works back from a shoulder strain that idled him for nearly two months. He emerged as a prospect in 2024 at Triple-A Reno and acquitted himself well in a cup of coffee in the majors. The view is that Del Castillo needs improvement in some areas behind the plate, but the bat could play in the majors. Once ready, he's expected to be assigned to Reno.

Diamondbacks' Adrian Del Castillo: Sent to Triple-A
Rotowire
The Diamondbacks optioned Del Castillo to Triple-A Reno on Friday.
Del Castillo missed out on Arizona's Opening Day roster after going 3-for-24 with 12 strikeouts in nine spring games. The 25-year-old could still see the big leagues at some point this season but isn't likely to see much playing time if Gabriel Moreno stays healthy.

Diamondbacks' Adrian Del Castillo: Optioned to Reno
Rotowire
Arizona optioned Del Castillo to Triple-A Reno on Monday.
With top catcher Gabriel Moreno returning from the 10-day injured list Sunday, the Diamondbacks will roll with Jose Herrera as the No. 2 backstop. Del Castillo is slashing .313/.368/.525 over 87 major-league plate appearances this season, but he'll have an everyday role in Reno for the tail end of the Triple-A season. The move makes room on the Diamondbacks' 28-man roster for right-hander Scott McGough.

Diamondbacks' Adrian Del Castillo: Pops homer in win
Rotowire
Del Castillo went 2-for-4 with a double, a home run, three RBI and an additional run scored in Wednesday's 14-4 win over the Rangers.
After the Rangers plated two runs in the top of the fifth inning, Del Castillo responded immediately with a three-run blast. He continues to split time behind the dish with Jose Herrera until Gabriel Moreno (thigh) is ready to return. The injured Moreno ramped up his activity this week, and the Diamondbacks are hoping for his return by mid-September. After an explosive debut to his MLB career -- three homers, 14 RBI in his first 48 at-bats -- Del Castillo has cooled off and entered Wednesday's contest hitting .130 (3-for-23) over the previous eight games.
