Arizona Diamondbacks

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.

Jordan Lawlar

LF

Once the team assesses the state of Lawlar's wrist, they can determine which baseball activities he can ramp up. An earlier report indicated he was doing as much baseball activity as possible without using the right wrist. A ramp up could involve getting a bat in his hands and taking swings. Lawlar is scheduled to return in early June.

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.

Corbin Burnes

SP

Burnes has been throwing occasional bullpen sessions since spring training -- Tuesday's session was his fourth -- so there was nothing significant about Tuesday's activity. "He just wants to make sure everything is feeling right, he's duplicating his delivery," Diamondbacks manager Torey Lovullo said of Burnes. The pitcher is still on track to return near or after the All-Star break.

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.

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.

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.

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.

A.J. Vukovich

CF

There is some important context needed with Vukovich's season line, as he had a .977 OPS in the very hitter-friendly home park in Amarillo and had a .681 OPS on the road. His 31.2 percent hard-hit rate is a strong mark, and Vukovich has always had a chance for above-average game power. He's made 60 starts in center field, 24 starts in left field, 15 starts at third base and a handful of starts at first base, right field and designated hitter.

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.

A.J. Puk

RP

The earliest date Puk can be activated from the 60-day injured list is May 21, and the reliever estimated he'd be "facing batters or starting rehab games" around then. The left-hander is four bullpen sessions in and will throw at least another six before facing hitters.

Pavin Smith

1B

Smith underwent surgery April 16 to remove loose bodies from his left elbow. He's currently on the 60-day injured list and can return May 29 at the earliest.
