Ready for 2026 debut with Arizona
The Diamondbacks reinstated Martinez (elbow) from the 60-day injured list Monday.
Analysis
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 moves to Triple-A
Martinez (elbow) struck out two and over a perfect inning in a rehab appearance for Triple-A Reno on Tuesday.
Analysis
Martinez moved his rehab up from Single-A Visalia to Reno for the third appearance of his rehab. Between the two stops, the right-hander has struck out five and allowed no hits and one walk over three scoreless frames. Martinez is scheduled for at least one more appearance with Reno on Thursday, per Alex Weiner of ArizonaSports.com, but Martinez could be activated at some point during the team's road trip, which runs Friday through Wednesday.
