Martinez is set to undergo season-ending Tommy John surgery after being diagnosed last week with a UCL sprain in his right elbow. The procedural move frees up a spot on Arizona’s 40-man roster.

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.

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.

Tightness doesn’t sound bad, but that’s pretty much always the initial diagnosis these days, and we’re assuming there’s a good chance Martinez, who was on the IL last month with shoulder inflammation, will land back on the injured list. Shelby Miller will be the clear favorite for saves in the Arizona pen while Martinez is sidelined, and he’s worth picking up in most leagues.

Martinez certainly made this one interesting. He came into this game with one out and two on in the eighth inning and got two strikeouts sandwiched around an intentional walk to Ronald Acuña Jr. to get out of it. Then, he returned for the ninth, loaded the bases with two walks and a hit batsmen, walked in a run, and finally struck out Michael Harris II to end the game a whopping 37 pitches later. This was the second time in four outings since coming off the injured list where he’s allowed a run.

Martinez looked like a dominant force in this one, getting Keibert Ruiz on a pop out to first base to start the inning before striking out Jose Tena and Daylen Lile in succession to end it. He needed just 13 pitches (nine strikes) to get the job done in this one. On the season, Martinez now sports a 3.46 ERA, 1.08 WHIP and a 16/7 K/BB ratio over 13 innings on the season while securing four saves in his first five opportunities.

Martinez was thrown right into a high-pressure situation in his first appearance since coming off the IL, but he gave up a walk, a double and a single to turn a one-run lead into a deficit. Even if he had done well, it seems likely that Shelby Miller would have closed today. Martinez will probably have to wait a little longer for a ninth-inning save chance.

Martinez looked sharp on Saturday in a scoreless rehab outing in the Rookie-level Arizona Complex League, but the Diamondbacks want him to face some additional minor league hitters before returning to their high-leverage mix at some point later this week. The hard-throwing 23-year-old stopper is close to making it back to Arizona.

The Diamondbacks want to see the 23-year-old hurler in live game action at least once or twice before he’s deemed ready to return to their bullpen. If all goes according to plan, it sounds like Martinez could be back in the bullpen mix at some point next week.

Martinez was shut down earlier this month with shoulder inflammation and all indications are that he’s looked sharp since resuming a throwing program. There isn’t a clear timetable for his return at the moment, but all signs point to him returning to Arizona’s high-leverage mix by the end of May.

Martinez has been shut down since the beginning of May due to inflammation in his shoulder. While an MRI didn’t reveal any structural damage, the Diamondbacks are struggling to pinpoint the reason for Martinez’ shoulder woes and his diminished velocity. They’ll take a cautious approach as they build him back up. There’s still no clear timetable for when he may be able to rejoin the D’Backs’ bullpen.

Diamondbacks manager Torey Lovullo said Martinez will “pick up a baseball and start throwing later this week.” Depending on how his shoulder feels as he starts throwing again, Martinez will progress to bullpens and then, most likely, a rehab assignment.

The plot thickens. The search for answers continues after Martinez was finally put on the injured list earlier this week with right shoulder inflammation. It’s an encouraging development that he’s not facing an extended absence, but there hasn’t been a compelling explanation for the hard-throwing 23-year-old’s diminished velocity and ongoing struggles.

Martinez struggled in Wednesday’s appearance against the Mets and was unable to record an out, and it appears he suffered more than a hit to his ERA. The 23-year-old right-hander will be out at least two weeks, but there should be more clarity on his timeline in the coming days. José Castillo will be up to help the D-Backs’ bullpen, but this will likely be a closer-by-committee situation.

Martinez’s velocity has been well down in his last two appearances, both of which have gone very poorly. Ryan Thompson could be the favorite for saves in the Arizona pen for now, though Kevin Ginkel, who just made his season debut last night after a stint on the IL, is probably the best long-term bet.

Lovullo added that Martinez is undergoing further evaluation after his velocity was down significantly during Wednesday’s relief appearance against the Mets. The hard-throwing 23-year-old was pulled in the ninth inning after giving up a solo homer to Tyrone Taylor and issuing consecutive walks to Francisco Lindor and Juan Soto. It was Ryan Thompson who came on to escape the jam and pick up the save. It certainly sounds like the Diamondbacks are considering giving him some time off to rest and focus on getting back to his previous form.

Martinez was able to nail down the save against the Braves, but his four-seamer was down three mph, and his sinker was 2.6 mph slower than his yearly average. He threw 15 of his 26 pitches for strikes, and there’s some real concern that his shoulder is just not right. Even if there isn’t a major injury, it might make sense for Arizona to rest him for a little bit until he’s 100 percent right. That could mean save opportunities for Shelby Miller and Kevin Ginkel, who is set to come off the IL this week.

Martinez opened the inning with a hit by pitch and a walk. He induced a double-play ball afterwards, but he then allowed an RBI double and a second walk before getting fly to center to end the game. Often very wild in the minors, Martinez has been quite a bit better than expected in that area as a major leaguer, particularly in opening this season with an 11/2 K/BB in nine innings. Especially with A.J. Puk out, it’d be bad if his control started to wane now.

Martinez has been shelved since last Thursday due to shoulder fatigue, but he told reporters on Friday that he’s good to go now. We’d surely like to see him demonstrate that on the field before taking his word for it, and if a save chance arises on Friday night we should get that chance.

Martinez hasn’t pitched since last Thursday due to shoulder fatigue, but there’s no indication he’ll wind up requiring a trip to the injured list. It would likely be some combination of Shelby Miller, Ryan Thompson and Drey Jameson handling a save chance on Wednesday night if Martinez isn’t able to go.

Lovullo had mentioned that Martinez was experiencing shoulder fatigue but has downplayed the issue as being anything serious. “I feel very strongly that today could be the day for him to come back.” With A.J. Puk sidelined by elbow discomfort, the Diamondbacks could certainly use Martinez back in action.

Martinez dealt with some fatigue over the weekend, but it doesn’t sound like a concern heading into Tuesday’s series opener against the Rays at Chase Field. The hard-throwing 23-year-old righty is expected to handle the bulk of the save chances for Arizona with A.J. Puk (elbow) likely facing an extended absence.

It was a bit surprising to see the 23-year-old right-hander not deployed during the extra-inning affair, so it’s good to hear that it’s just general fatigue and not any sort of injury that Martinez is dealing with. It sounds like he should be able to return to action in a day or two, but it’s still a situation that fantasy managers should probably monitor just in case.
