Justin Martinez (elbow) struck out two in a perfect inning during a minor league rehab outing for Triple-A Reno on Tuesday.

Martinez touched triple digits six times and topped out at a sizzling 102.4 mph during the 11-pitch outing. It was his first game action since undergoing Tommy John surgery last summer. The flame-throwing 25-year-old looks like Arizona’s closer of the not-so-distant future. He’ll require a couple additional outings before he’s ready to return to the majors, but he’s definitely close.

Justin Martinez (elbow) will begin a rehab assignment with Triple-A Reno.

Martinez had Tommy John surgery last June and is now in the final steps of his recovery. Given how long he’s been out, the Diamondbacks will likely want to keep him in Triple-A for a couple weeks and have him build up to back-to-backs, but he should return to the Diamondbacks bullpen by the end of the month.

Justin Martinez (elbow) will progress to facing hitters on Wednesday in a live batting practice session.

Diamondbacks skipper Torey Lovullo said that Martinez could be ready for minor league rehab outings afterwards. The hard-throwing 24-year-old former closer is working his way back from last year’s Tommy John surgery and should make it to Arizona at some point in mid-to-late August based on his present trajectory.

Justin Martinez (elbow) is set to face live hitters in the coming days.

Diamondbacks manager Torey Lovullo said, “Martinez is just about to step onto a mound in lives. I don’t know the exact day when he’s going to face his lives, but he’s very close, very close.” Martinez had Tommy John surgery last June and had been targeting an August return. As of now, he seems on track to return at some point in August but might need time to work back into leverage innings.

Justin Martinez, who is making his way back from Tommy John surgery, threw his first bullpen session Friday and reportedly was in the upper-90s.

“I heard it was electric,” manager Torey Lovullo said. Martinez might rejoin the mix for saves in the D-backs bullpen in in July. However, A.J. Puk, another contender for ninth-inning duties, is expected to beat him back.

Diamondbacks placed RHP Justin Martinez on the 60-day injured list.

Martinez will miss at least the first half of the upcoming season while recovering from last year’s Tommy John surgery. The hard-throwing 24-year-old former closer should return to Arizona’s high-leverage mix at some point in August, barring any setbacks. The procedural move frees up a spot on the club’s 40-man roster for veteran hurler Paul Sewald.

Justin Martinez (elbow) told reporters on Tuesday that he’s targeting August for a return to the Diamondbacks’ bullpen.

The 24-year-old hurler underwent Tommy John reconstructive elbow surgery last June. It’s possible that he’s being a bit optimistic with that return date, but it sounds like everything has gone smoothly in his recovery to this stage. Getting him back at all in 2026 would provide a welcomed late-season boost to the Diamondbacks’ bullpen.

Diamondbacks’ manager Torey Louvllo confirmed Friday that right-hander Justin Martinez will undergo Tommy John reconstructive elbow surgery.

We already knew that the 23-year-old right-hander was dealing with a UCL sprain and likely heading under the knife, but now it has been confirmed. He’ll miss the remainder of the 2025 season and most of the 2026 campaign as well while recovering from the procedure.

Diamondbacks manager Torey Lovullo told reporters that Justin Martinez will miss 12-13 months with the UCL sprain in his right elbow.

Martinez was diagnosed with his sprain Tuesday, and while the 23-year-old is awaiting a second opinion, the Diamondbacks still have ruled out the right-hander for the rest of this season and a large portion of 2026, as well. The question will be whether or not Martinez will undergo surgery and what type of operation it would be, but he won’t be a high-leverage option for Arizona for a while, at best.
