May 12, 2025 7:45 PM : Martinez (shoulder) will throw to live hitters Wednesday, Alex Weiner of ArizonaSports.com reports.
Analysis: Martinez felt strong after completing a bullpen session Sunday, and it's another positive sign that he's progressing to throwing against hitters Wednesday. The Diamondbacks haven't indicated whether the 23-year-old will require a minor-league 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. Arizona will presumably wait and see how Martinez comes out of the live session Wednesday before deciding on his next step.
