Diamondbacks injury return tracker: Progress reports on Justin Martinez, Corbin Burnes

PHOENIX — The Arizona Diamondbacks activated the first out of an expected wave of reinforcements coming off the injured list on Monday, reinstating starting pitcher Michael Soroka.

Soroka suffered a left glute strain on June 19, a hit to Arizona’s starting rotation as the first-year D-back had been terrific through the first two-plus months of the campaign (3.07 ERA).

The Diamondbacks are hoping to improve their roster internally as the season progresses, and there is a pair of key players on Soroka’s tail before another wave could hit as the calendar approaches September.

In the midst of a playoff race, the Diamondbacks could use any help they can get, although there is a balance of pushing to the finish line and needing grace with players who, in some cases, have not played in over a year.

Here is a tracker that will be updated to provide fans a window into the return progress, setbacks and potential timelines for these players making their way back:

10-day IL

Outfielder Jordan Lawlar, right hamstring strain — IL since June 20

Lawlar participated in his fifth rehab game for Double-A Amarillo on Sunday, playing on a third straight day. He will play more games for Amarillo on Tuesday and Wednesday.

Lawlar and reliever Justin Martinez are expected to be next in line to return after Soroka, as manager Torey Lovullo left the possibility open for the outfielder to get back on Arizona’s upcoming road trip to Atlanta and Boston.

Outfielder Lourdes Gurriel Jr., right adductor strain — IL since July 18

Gurriel took five at-bats in a Bridge League game on Saturday as a designated hitter, but he did not run at full intensity.

Gurriel continues to work on his running progression and outfield drills. He will play in another Bridge League game on Tuesday.

Outfielder Tommy Troy, right AC joint sprain — IL since July 12

Troy took three at-bats in live batting practice on Saturday.

He will play in Bridge League games on Tuesday and Thursday as he continues to work on his range of motion and throwing mechanics.

15-day IL

Relief pitcher Drey Jameson, right hip inflammation — IL since July 20

Jameson threw two innings and 32 pitches in a Bridge League game on Saturday.

Lovullo said Jameson developed a blister, which will push him back a few days, but the plan is to get him rehab work at Triple-A Reno this upcoming weekend.

Relief pitcher Ryan Thompson, strained lower back — IL since Aug. 5

Thompson started his throwing program on Monday.

60-day IL

Relief pitcher Justin Martinez, Tommy John surgery — last pitched on June 9, 2025

Martinez made his second rehab appearance for Single-A Visalia on Friday, throwing 14 pitches and another 11 in the bullpen after.

He is scheduled to pitch for Triple-A Reno on Tuesday.

Starting pitcher Corbin Burnes, right elbow surgery/teres major strain — last pitched on June 1, 2025

Burnes threw a 25-pitch bullpen on Friday as he continues to fight to get back on the mound this season. Burnes will throw another bullpen on Tuesday.

The 2021 Cy Young winner dealt a setback earlier this season, as it was announced on June 1 that he suffered a teres major strain while ramping up from elbow surgery.

Burnes has only made 11 starts after signing a six-year, $210 million deal with Arizona before the 2025 campaign.

Starting pitcher Zac Gallen, right elbow inflammation — IL since July 19

Gallen threw a 25-pitch bullpen on Friday after his latest imaging showed some “resolution.” He will throw another bullpen on Tuesday.

Lovullo said there is a target date for Burnes and Gallen to return, but he wants to take it step-by-step before laying that out.

Starting pitcher Ryne Nelson, right elbow strain/sprain — IL since June 16

Nelson threw on flat ground on Friday and is out to 120 feet.

Lovullo said on Monday that Nelson would begin his bullpen progression in the next seven to 10 days.

The idea of bringing him back as a relief pitcher to shorten his ramp-up time has been discussed, especially with Soroka, Burnes and Gallen coming back or on the path to return by the end of the season.

Starting pitcher Blake Walston, Tommy John surgery — has not pitched in MLB since 2024

Walston made his second rehab appearance for Triple-A Reno on Saturday, throwing two innings and 23 pitches. Walston will pitch again for Reno on Wednesday.

Diamondbacks ruled out for the season

• Relief pitcher A.J. Puk (left elbow surgery/left capsule sprain)
• Starting pitcher Cristian Mena (right shoulder surgery)
• Relief pitcher Andrew Saalfrank (left shoulder surgery)
