Justin Martinez - MLB News, Rumors, & Updates

Makes season debut Martinez allowed one walk over a scoreless inning in Tuesday's 9-4 loss to Boston.

Impact Martinez made his first appearance since being reinstated from the 60-day injured list Monday. It's been 435 days since he last pitched in the majors, as Martinez spent that time recovering from a second Tommy John elbow surgery. The right-handed reliever and one-time closer came on to pitch the ninth inning, which suggests he may return to the closer's role for the Diamondbacks down the stretch.

Ready for 2026 debut with Arizona The Diamondbacks reinstated Martinez (elbow) from the 60-day injured list Monday.

Impact Martinez has been cleared to make his 2026 debut with the Diamondbacks following a lengthy recovery from Tommy John surgery, which he underwent June 25, 2025. The hard-throwing reliever looked sharp over his four rehab appearances between Single-A Visalia and Triple-A Reno, firing four scoreless, no-hit innings while striking out six and issuing just one walk. The Diamondbacks' closer situation has been unsettled over the past three weeks after Paul Sewald lost the job and eventually, his roster spot, so Martinez could make for a viable speculative pickup for fantasy managers mining for saves. Before requiring surgery last summer, Martinez had previously been a key high-leverage arm for Arizona in 2024 and the early part of the 2025 season.

Rehab beginning Tuesday Martinez (elbow) will begin a rehab assignment at Single-A Visalia on Tuesday, MLB.com reports.

Impact Martinez participated in a camp game Friday and reportedly hit 100-plus mph on his four-seamer. The recent upheaval in the Diamondbacks' bullpen -- Paul Sewald was removed as closer and the club is using a committee approach -- indicates Martinez could get back to being the team's closer. That may not happen in 2026, but Martinez should get an opportunity to show his stuff in September.

Nearing rehab assignment Martinez (elbow) is expected to begin a rehab assignment at Single-A Visalia next week, Steve Gilbert of MLB.com reports.

Impact 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.
