Arizona Diamondbacks

Cristian Mena

RP

Mena sustained a teres major strain in his right shoulder in June of 2025, which caused him to miss the rest of that season. He opened 2026 on the 60-day IL and was cleared to resume his throwing program in mid-May. However, it appears Mena suffered another setback in his recovery, and his shoulder injury is severe enough for him to undergo a season-ending procedure. The hope for the Diamondbacks is that the surgery will have the 23-year-old fully healthy for the start of spring training in February.

Carlos Santana

1B

Santana had appeared poised for activation from the 10-day injured list ahead of Monday's game against the Rangers, but his status is now up in the air. The 40-year-old was functioning as the Diamondbacks' primary first baseman before getting hurt in early April, but with the emergence of Ildemaro Vargas, Santana could be looking at a reduced role when he does make it back.

Blake Walston

SP

Arizona hasn't provided any concrete information regarding where Walston currently stands in the rehab process, but he's not expected to be a realistic candidate to return from the 60-day injured list until after the All-Star break. The 24-year-old left-hander hasn't made an appearance in an official game since spring training of last year after undergoing Tommy John surgery March 26, 2025.

Jordan Lawlar

LF

Lawlar also had an outfield assist while playing all seven innings. Arizona manager Torey Lovullo said Saturday that Lawlar will play at least one more game in the ACL before shifting to a higher level to continue his rehab assignment.

A.J. Puk

RP

The outing was Puk's third in the ACL while on a rehab assignment. He's allowed two hits and struck out two over three scoreless appearances. The reliever is expected to shift his rehab to Triple-A Reno on Tuesday.

Corbin Burnes

SP

The rehabbing Burnes faced the rehabbing Jordan Lawlar (wrist), the first time each player faced an opponent during the rehab. Next up for Burnes is another batting practice session Tuesday. The right-hander is expected to return mid-season, likely following the All-Stat break.

A.J. Vukovich

CF

no

Lourdes Gurriel Jr.

LF

Gurriel injured his hamstring while sliding to make a catch in the outfield Friday, leading to his placement on the 10-day IL. It sounds like both the player and team expect him back when he's first eligible to return on June 2, but in the meantime, Tommy Troy will get a look in left field for the Diamondbacks.

Derek Law

RP

no

Spencer Giesting

SP

James McCann

C

McCann landed on the injured list Tuesday with a quad strain, and it doesn't seem like the Diamondbacks are going to get their backup catcher back anytime soon. Aramis Garcia was recalled from Triple-A to replenish Arizona's backstop depth behind Gabriel Moreno. Adrian Del Castillo could make an occasional appearance behind the plate as well.

Justin Martinez

RP

This was Martinez's first time throwing off a mound since he underwent Tommy John surgery on his right elbow last July. Per Piecoro, the reliever was at 96-to-99 mph with his fastball during the bullpen session. Martinez still has several more hurdles to clear and plenty of ramp-up, and he's not expected to be ready to return to Arizona's bullpen until sometime after the All-Star break.

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.

Kyle Amendt

RP

Amendt, a ninth-round pick in 2023 out of Dallas Baptist University, didn't bring a lot of cache to the organization, but the right-hander emerged in 2024. Among the minor-league pitchers who worked at least 40 innings, Amendt ranked fifth in both K/9 (15.3) and strikeout percentage (40.3), per Jesse Borek of MLB.com. He was a closer in college and worked out of the bullpen at High-A Hillsboro, Double-A Amarillo and Triple-A Reno. There was initially a challenge at Reno -- he allowed multiple runs in his first two appearances -- but he finished with a 1.80 ERA over his final 11 outings. Amendt uses a fastball and curveball, which tends to break away from lefties due to his unique delivery.
