Arizona Diamondbacks

Justin Martinez

RP

Martinez has been on the injured list all season while working his way back from Tommy John surgery. He's been cleared to face hitters for the past two weeks, and he's scheduled to pitch in a simulated game at the team's spring training complex this weekend before joining one of Arizona's minor-league affiliates. The 25-year-old righty will likely require an extended rehab assignment after spending more than a year on the shelf, but he could still make it back to the D-backs' bullpen before the end of August.

Michael Soroka

SP

Soroka is slated to throw 4-to-5 innings and/or 50-to-60 pitches in the outing. It will be his first time appearing in a game since he went down with a left glute strain in late June. The right-hander could be ready to rejoin the Diamondbacks' rotation after Tuesday's start, though the club might prefer Soroka to get stretched out further before reinstating him. He boasts a 3.07 ERA and 79:17 K:BB over 82 innings covering 15 starts for Arizona this season.

Zac Gallen

SP

Gallen received a second opinion from Dr. Neal ElAttrache, who granted the right-hander permission to begin throwing again. An estimated return for Gallen has yet to be determined.

Jordan Lawlar

LF

Lawlar's experienced improvement over the last week. He was not yet at full speed one week ago but is now on the precipice of participating in bridge games at the Diamondbacks' training facility in Arizona. Diamondbacks manager Torey Lovullo confirmed Friday that the bridge game activity should occur in the coming days.

Drey Jameson

RP

The move corresponds with Kade Strowd being optioned to Reno following Friday's game against the Nationals. Jameson has spent the entire 2026 season in Triple-A, where he has a 7.33 ERA, 1.60 WHIP and 23:12 K:BB across 23.1 innings. He appeared in three regular-season games for the Diamondbacks in 2025, when he allowed two runs (one earned) on four hits and three walks over three innings while logging one save.

Lourdes Gurriel Jr.

LF

Gurriel went 0-for-3 with a sacrifice fly in Friday's loss, and he'll now retreat to the bench to begin Saturday's game. Gabriel Moreno will replace him as Arizona's designated hitter, giving James McCann a start at catcher.

A.J. Puk

RP

Puk has been on the injured list all season while recovering from an internal brace procedure he underwent last summer, as well as a shoulder capsule sprain he suffered while pitching in a rehab game. The results of his latest MRI suggest that his stay on the IL is likely to be extended even further, and he's set to visit Dr. Neal ElAttrache within the next couple of days to help determine next steps. An updated timeline for his return could come into focus following his appointment.

Ryne Nelson

SP

Manager Torey Lovullo said Saturday that Nelson has shown a lot of improvement since landing on the injured list June 19 with a strained right elbow. The team still believes that the right-hander will be able to pitch again for the big club this season, though it's still unclear whether he'll do so as a starter or a reliever. A better idea of his return timeline and expected role should emerge as he clears hurdles in his throwing program.

Andrew Saalfrank

RP

The throwing program began with Saalfrank tossing out to 60 feet. The left-hander underwent shoulder surgery ahead of spring training and is considered out for the season.

Tommy Troy

LF

A sprained AC joint in Troy's right shoulder caused him to move to the injured list Wednesday, and it now seems like he won't be able to make it back before the end of the month. The 24-year-old had been getting opportunities to start in center field with Jordan Lawlar (hamstring) on the shelf, but those reps will now likely be passed on to Ryan Waldschmidt and Jorge Barrosa.

Corbin Burnes

SP

Burnes had been working his way back from Tommy John surgery during April and May but was forced to shut down in early June. The plan calls for him to throw off flat ground every other day and then progress to throwing off a mound. The Diamondbacks hope the right-hander can return in time for a September playoff push.

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.

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.
