Jun 15 2025The Diamondbacks (elbow) transferred Martinez (elbow) from the 15-day injured list to the 60-day IL on Sunday. ROTOWIRE RECOMMENDS: Manager Torey Lovullo announced Friday that Martinez will require season-ending Tommy John surgery, so it was just a matter of time before the right-hander was shifted to the 60-day IL. In addition to missing the rest of the 2025 season, Martinez will spend most, if not all, of the 2026 campaign recovering from the procedure.
Jun 13 2025Diamondbacks manager Torey Lovullo said Friday that Martinez (elbow) will undergo Tommy John surgery, Aaron Hughes of SI.com reports. ROTOWIRE RECOMMENDS: Martinez was already ruled out for the rest of the 2025 season due to a UCL sprain in the right elbow. After multiple consults, the 23-year-old will undergo Tommy John surgery for a second time after going through with the procedure in 2021. Given the timeline for recovery, Martinez will miss a significant portion of the 2026 season. Shelby Miller is the next man up to take on closing duties for Arizona in Martinez's absence.
Jun 10 2025The Diamondbacks placed Martinez on the 15-day injured list Tuesday due to a sprained UCL in his right elbow. ROTOWIRE RECOMMENDS: The right-hander experienced tightness in the elbow during the ninth inning of Monday's contest, and a UCL sprain is an ominous initial diagnosis. The severity of the issue isn't yet known, and manager Torey Lovullo said Martinez is headed for a second opinion on the MRI result, per Nick Piecoro of The Arizona Republic. Even a low-grade sprain could require a lengthy absence, with Tommy John surgery likely being the worst-case scenario. Shelby Miller is likely to be the next man up as Arizona's closer.
Jun 9 2025Martinez left Monday's game against the Mariners with an undisclosed injury, Jack Sommers of SI.com reports. ROTOWIRE RECOMMENDS: Martinez was one out away from recording his sixth save of the season, but he made a motion for the trainer after throwing a 97 mph sinker to Donovan Solano. Martinez is presumably headed for further evaluation to determine the severity of his injury. Jeff Brigham was deployed in Martinez's stead.
Jun 4 2025Martinez registered the save in Wednesday's 2-1 victory over Atlanta, allowing one run on no hits and four walks with four strikeouts in 1.2 innings. ROTOWIRE RECOMMENDS: It was certainly a shaky outing by Martinez despite allowing no hits, as he gave up a season-high four walks while throwing just 17 of his 37 pitches for strikes. It was encouraging to see manager Torey Lovullo trust Martinez to record five outs for his fifth save of the year, but the hard-throwing right-hander seems unlikely to be available for Thursday's series finale against Atlanta after tossing so many pitches Wednesday. Despite owning a 5.79 ERA, 1.50 WHIP and 9:5 K:BB over 4.2 innings since coming off the injured list, Martinez still appears to be the favorite for saves in Arizona's bullpen.
Jun 1 2025Martinez struck out two in a perfect inning to earn the save in Sunday's 3-1 win over the Nationals. ROTOWIRE RECOMMENDS: Martinez had been eased back into closing duties since returning from a shoulder injury that cost him most of May. This was his third appearance since coming off the injured list, and he closed the game out after picking up a hold in his last outing Monday versus the Pirates. Martinez is up to four saves, four holds and a blown save over 15 appearances this season. He's also pitched to a 3.46 ERA, 1.08 WHIP and 16:7 K:BB across 13 innings. Late-inning duties could continue to be split between Martinez and Shelby Miller in the short term, but the closing job should eventually tilt in Martinez's favor as long as he performs well.
May 27 2025Martinez struck out one over a scoreless inning to earn a hold in Monday's 5-0 win over Pittsburgh. ROTOWIRE RECOMMENDS: Martinez's hold felt like a save. He entered the eighth inning with none out and the bases loaded and got a strikeout, popout and groundout. At the time when Martinez was activated off the injured list, Arizona manager Torey Lovullo indicated he'd prefer to ease him back before returning Martinez to a ninth-inning role, but Monday's outing may have jump-started the move back to closer.
May 24 2025Martinez (1-2) was charged with his first blown save of the season and took the loss Saturday against the Cardinals, coughing up two runs on two hits and a walk in one inning. He struck out two. ROTOWIRE RECOMMENDS: Brought on in the bottom of the eighth inning to protect a 4-3 lead in his first action since coming off the IL on Friday, Martinez struck out the first batter he faced but quickly ran into trouble before giving up a two-out, two-run single to Jordan Walker. The usage suggests Shelby Miller would have been used in the ninth if Arizona still held the lead, but it might only take a couple clean appearances for Martinez to regain the closer role. That's easier said than done, however -- he's been tagged for a run in four straight games dating back to late April, prior to being shut down with shoulder inflammation. On the bright side, Martinez showed his usual elite velocity Saturday as he hit triple digits on the radar gun with six of his 23 pitches.
May 23 2025The Diamondbacks activated Martinez (shoulder) from the 15-day injured list Friday. ROTOWIRE RECOMMENDS: Martinez has been shelved for most of May with right shoulder inflammation but is ready to go after making two scoreless rehab appearances. He reached 101.1 mph with his sinker during his last outing at Triple-A Reno, which is particularly encouraging after his velocity had dipped prior to the IL stint. Martinez might be eased back into ninth-inning duty, but it shouldn't be long before he reclaims the closer role with Shelby Miller carrying a 5.63 ERA and 2.13 WHIP in May.
May 22 2025Diamondbacks manager Torey Lovullo said after Wednesday's 3-1 loss to the Dodgers that Martinez (shoulder) has a good chance to return from the 15-day injured list for this weekend's series in St. Louis, Jody Jackson of Bally Sports Arizona reports. ROTOWIRE RECOMMENDS: Martinez has been on the shelf since May 1 due to right shoulder inflammation, an injury that resulted in a significant drop in velocity in his last couple of relief appearances before he was deactivated. The right-hander seems to have bounced back nicely from the extended rest, as he tossed scoreless innings in both of his minor-league rehab appearances and reached 101.1 miles per hour with his sinker during his most recent outing with Triple-A Reno on Tuesday. Per John Gambadoro of 98.7 FM Arizona Sports, Martinez flew back to Phoenix on Wednesday, and assuming the Arizona training staff was satisfied with his health, he'll accompany the Diamondbacks on their road trip and will likely be activated Friday. Martinez should eventually settle back in as the Diamondbacks' preferred option at closer, though it's possible that manager Torey Lovullo chooses to ease him back in with a low-leverage appearance or two.
May 21 2025Martinez (shoulder) allowed one hit over a scoreless inning for Triple-A Reno on Tuesday. ROTOWIRE RECOMMENDS: Martinez made his second appearance while on rehab assignment after throwing an inning in an Arizona Complex League game Saturday. The reliever completed the 15-day IL minimum last Friday, and manager Torey Lovullo expressed optimism throughout Martinez's IL stint that the right-hander would be back at or near the minimum requirement. The manager may wish he activated Martinez sooner, as the Diamondbacks blew a late lead in a 4-3 extra-inning loss to the Dodgers on Tuesday.
May 18 2025Martinez (shoulder) is scheduled to throw an inning for Triple-A Reno on Tuesday as part of his rehab assignment, Jody Jackson of Bally Sports Arizona reports. ROTOWIRE RECOMMENDS: Martinez is working his way back from right shoulder inflammation and is nearing a return. A report Sunday indicated he'd rejoin the team either for the start of a series against the Dodgers on Monday or for a weekend set against St. Louis beginning Friday. With Martinez throwing an inning for Reno on Tuesday, it's expected he'll rejoin the big-league club ahead of its series against the Cardinals.
May 17 2025Martinez (shoulder) could be activated to start the Diamondbacks series against the Dodgers on Monday, or the team could wait until its series against the Cardinals on Friday, Jack Sommers of SI.com reports. ROTOWIRE RECOMMENDS: Martinez made his first rehab appearance in the Arizona Complex League on Saturday. The next step will either be activation or having his rehab assignment transferred to Triple-A Reno. Regardless of his exact return date, Martinez should take the mound within the next week for the Diamondbacks.
May 16 2025Diamondbacks Torey Lovullo said Friday that Martinez (shoulder) will throw in the Arizona Complex League on Saturday, Nick Piecoro of The Arizona Republic reports. ROTOWIRE RECOMMENDS: Martinez is in the final stages of his recovery from right shoulder inflammation, which caused him to be placed on the 15-day injured list in early May. He progressed to facing live batters earlier this week, and he'll take the next step in his rehab program by throwing in an ACL game Saturday. Martinez could return to the big club shortly after Saturday's outing depending on how his shoulder responds.
May 12 2025Martinez (shoulder) will throw to live hitters Wednesday, Alex Weiner of ArizonaSports.com reports. ROTOWIRE RECOMMENDS: Martinez felt strong after completing a bullpen session Sunday, and it's another positive sign that he's progressing to throwing against hitters Wednesday. It remains unclear if the D-Backs will send the 23-year-old out on a rehab assignment, as he'll be eligible to be activated from the 15-day injured list Friday after going down with shoulder inflammation at the beginning of the month.
May 10 2025Martinez (shoulder) will throw a bullpen session Sunday, Nick Piecoro of The Arizona Republic reports. ROTOWIRE RECOMMENDS: Manager Torey Lovullo said Saturday that the ball has been "sizzling" out of Martinez's hand during his throwing program, which is a sign that the 23-year-old is feeling good after landing on the injured list May 1 with shoulder inflammation. Assuming all goes well during his bullpen session, Martinez may still be on pace to return when eligible next Friday.
May 9 2025Martinez (shoulder) extended his throwing program out to 90 feet Thursday and could get back on a mound this weekend, Alex Weiner of Arizona Sports reports. ROTOWIRE RECOMMENDS: Martinez began his throwing program earlier in the week and may need just the minimum stay on the 15-day injured list, per manager Torey Lovullo. "I know you guys want to know on Day 16 is he gonna be available?" Lovullo said. "I think it's gonna potentially be around that time. It's not gonna be much longer than that if it's not on that day." Since Martinez landed on the IL, Shelby Miller and Kevin Ginkel have been given save opportunities.
May 8 2025Martinez (shoulder) began a throwing program Tuesday and will pitch in Arizona Complex League games next, MLB.com reports. ROTOWIRE RECOMMENDS: The Diamondbacks are hopeful Martinez will be able to return at the end of his 15-day stint on the injured list. He had experienced diminished velocity in a couple of outings before being placed on the IL but imaging came back clean for any structural damage.
May 5 2025Martinez (shoulder) will begin throwing later this week after being placed on the 15-day injured list Thursday, Alex Weiner of ArizonaSports.com reports. ROTOWIRE RECOMMENDS: Martinez was placed on the 15-day IL with right shoulder inflammation Thursday, but he received promising imaging results Saturday, which didn't show any structural damage. The relief pitcher is first eligible to return to action May 16, but it's far too early to place a timeline on when he'll be able to make his return to the mound. Once Martinez picks a ball up later this week, there will be a better understanding of where he's at physically.
May 3 2025Martinez had an MRI on his right shoulder that showed no structural damage, Steve Gilbert of MLB.com reports. ROTOWIRE RECOMMENDS: Martinez experienced a drop in velocity during his past two appearances, including in Wednesday's relief outing against the Mets, and was subsequently placed on the 15-day injured list due to right shoulder inflammation. The righty received good news Saturday, however, as imaging didn't show any structural damage in the shoulder. Martinez is eligible to be activated from the IL on May 16, though it's not yet clear if he'll be ready to resume pitching in games at that point.
May 1 2025The Diamondbacks placed Martinez on the 15-day injured list Thursday with right shoulder inflammation. ROTOWIRE RECOMMENDS: Martinez's velocity and results have trended in the wrong direction lately, so the Diamondbacks are opting to shut him down for the time being. He is scheduled to undergo imaging to see if there is anything more serious beyond inflammation in his pitching shoulder. With A.J. Puk (elbow) also on the shelf, the Diamondbacks could mix and match at closer. Ryan Thompson, Shelby Miller and Kevin Ginkel are among the options to see save chances.
