Arizona Diamondbacks

Tommy Henry

RP

Henry was non-tendered by Arizona last month, but the two sides have reunited on a minor-league pact. The left-hander missed much of 2025 due to injury and could be out for all of next season following Tommy John surgery in June. Henry holds a career 5.07 ERA over 37 appearances (32 starts) at the big-league level.

Jordan Lawlar

SS

Lawlar was struck in the right hand/wrist in the bottom of the seventh inning by a sinker from relief pitcher Osvaldo Bido. He appears to have avoided any significant structural damage, but the 23-year-old will undergo a CT scan Friday to confirm that's the case. If Lawlar is forced to miss any action moving forward, Tim Tawa could stand to see some added opportunities in the outfield against right-handed pitchers.

A.J. Puk

RP

Puk is coming back from an internal brace procedure he underwent last June. Diamondbacks manager Torey Lovullo said Tuesday that his best guess is that Puk returns to the team at some point in June.

Lourdes Gurriel Jr.

LF

Diamondbacks manager Torey Lovullo said Tuesday that more intense game action in the Arizona Complex League could come soon, at some point in early-to-mid April. That's when he'll test at full speed. Lovullo reiterated that late April is the earliest the outfielder could return, and that Gurriel will operate as the designated hitter initially upon his activation.

Adrian Del Castillo

C

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 reports. He was placed on the 10-day injured list March 22, so he could be activated soon if his 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.

Merrill Kelly

SP

The plan for Kelly, fresh off a 35-pitch bullpen session Tuesday, is to get as close to or into the 70s with his pitch count Friday. This could be the only rehab start he makes before rejoining the Diamondbacks. Kelly was placed on the 15-day injured list retroactive to March 24, which means he could be activated as early as next Wednesday April 8.

Kyle Amendt

RP

Amendt finished the 2025 campaign with a 3.03 ERA and 1.54 WHIP over 29.2 innings at Triple-A Reno. The 25-year-old righty won't get the chance to follow up his breakout season, however, as his shoulder procedure will force him to sit out the entire 2026 season.

Pavin Smith

1B

Smith had started each of the previous two games after overcoming a sore elbow, but he'll begin Monday's festivities on the bench. Ildemaro Vargas will serve as the designated hitter and bat eighth for the Diamondbacks.

Blake Walston

SP

Walston will open a second consecutive season on the 60-day injured list after he was shelved throughout the 2025 campaign after undergoing Tommy John surgery March 26 of last year. Per Alex Weiner of ArizonaSports.com, Walston was spotted throwing off flat ground Feb. 10, but it's unclear if the southpaw has progressed to mound work since then. In any case, Walston will be out for at least the first two months of the 2026 campaign while he continues to build back up following surgery.

Cristian Mena

RP

Mena didn't pitch after June 6 last season after straining his right shoulder and had received a clean bill of health heading into spring training before aggravating the injury early in camp. The right-hander remains shut down from throwing and will now be shelved for at least the first two months of the season while he continues to rehab the injury.

Tyler Locklear

1B

Locklear was held out for the entirety of spring training while recovering from Oct. 16 surgeries to repair the labrum in his left shoulder and a torn ligament in his left elbow. He's not expected to be ready to return from IL until around mid-May to early June.

Justin Martinez

RP

The next milestone for Martinez sill be throwing from a mound. He underwent Tommy John elbow surgery last June and is shooting for a return by August.

Corbin Burnes

SP

Burnes threw a second bullpen session and mixed in curveballs after tossing 15 pitches (all fastballs) last Friday. The plan going forward calls for the right-hander to pitch again this coming Friday then two sessions per week for the next month. Burnes will incorporate all his pitches in those twice-weekly sessions. He estimated to be throwing at about an 80 to 85 percent effort level.

Andrew Saalfrank

RP

Saalfrank underwent surgery Monday to repair the left labrum in his shoulder and has already been placed on the 60-day injured list. The rehab timeline gives the lefty a chance to be ready for the start of the 2027 season, but it is not a given.

Derek Law

RP

Law missed all of last season due to a forearm/elbow injury he originally suffered near the end of 2024. He underwent surgery to address the issue in July and will likely remain sidelined until midway through the 2026 campaign. The 35-year-old reliever turned in a 2.60 ERA over 90 innings with the Nationals during his most recent MLB season and could be a factor in Arizona's bullpen once he's cleared to play.
