The Mets activated Nunez (elbow) from the 60-day injured list Tuesday.
The Mets traded away most of their bullpen at the deadline aside from closer Devin Williams, so Nunez could be thrust into a high-leverage role right away. The 30-year-old right-hander underwent Tommy John surgery in July 2025 and has looked good on his rehab assignment, posting a 3.00 ERA, 1.00 WHIP and 9:5 K:BB in nine innings for Triple-A Syracuse. In his most recent appearance Saturday, he appeared to be comfortably sitting around 96 mph with his fastball.
