Dbacks ref and notes

Diamondbacks manager Torey Lovullo said Sunday that Locklear (shoulder/elbow) is trending toward a return around mid-May to early June, Alex Weiner of ArizonaSports.com reports.

Locklear will be a spectator for spring training while he continues to recover from Oct. 16 surgeries to address a torn labrum in his left shoulder and a torn ligament in his left elbow. Before suffering the two arm injuries in a Sept. 7 collision at first base with Boston’s Connor Wong, Locklear slashed .175/.267/.262 with a 37.1 percent strikeout rate over 116 plate appearances with Arizona after coming over from Seattle in a trade-deadline deal. Locklear has a minor-league option remaining, so he could end up sticking around with Arizona’s Triple-A affiliate in Reno once he completes his rehab process and gets activated from the injured list.

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.

Soroka might open the season in the bullpen, Ken Rosenthal of The Athletic reports.

The Diamondbacks enter spring training well stocked in the rotation but with an unsettled outlook in the bullpen. Soroka, signed by Arizona as a free agent in December, made 17 starts for the Nationals and Cubs in 2025 before a shoulder injury limited him to relief work over the final two weeks of the regular season. Built into Soroka’s contract are incentives that reward him for starts or relief appearances — two points for every start, one point for a relief outing. He will earn $250,000 each for reaching 10 and 20 points, $425,000 each for reaching 30 and 40, and $650,000 for reaching 50. Barring a significant injury, the 28-year-old right-hander could reach those incentives as a full-time starter or reliever or a combination of the two roles.

The Diamondbacks placed Puk (elbow) on the 60-day injured list Sunday.

The left-hander will be unavailable for at least the first couple months of 2026 while rehabbing from Tommy John surgery, so his move to the 60-day IL is just a procedural move. After reporting for spring training last week, Puk said that he expects to make his season debut before July.

The Diamondbacks claimed Holman (finger) off waivers from the Athletics on Sunday.

The addition of Holman gives the Diamondbacks an intriguing developmental arm out of the bullpen. Though he struggled to a 5.09 ERA, 1.52 WHIP and 17:9 K:BB over 23 innings in the big leagues with the Athletics last season, the 6-foot-6 Holman boasts a four-pitch mix and long levers that helped him finish in the 94th percentile in extension, per Aaron Hughes of SI.com. Arizona placed A.J. Puk (elbow) on the 60-day injured list to clear a spot on the 40-man roster for Holman.
