Justin Martinez: Everything you need to know

Martinez (elbow) is throwing from up to 120 feet on flat ground, MLB.com reports. The next milestone for Martinez sill be throwing from a mound. He underwent Tommy John elbow surgery last June and is shooting for a return in the second half of the 2026 season.

The Diamondbacks placed Martinez (elbow) on the 60-day injured list Saturday. The move will create space on Arizona's 40-man roster for Paul Sewald, who signed with the club on Thursday. Martinez underwent Tommy John surgery in June and is expected to return to the D-backs' bullpen near the end of August.

Martinez (elbow) hopes to make his season debut by late August, Jack Sommers of SI.com reports. Recovering from Tommy John surgery that he had last June, Martinez began a throwing program in mid-January. He will continue with a deliberate pace to his rehab and likely begin a rehab assignment a little after the All-Star break if all goes well. Martinez had been serving as the Diamondbacks' closer before getting hurt but could retake his old gig late in the 2026 campaign.
