Overview
- Peralta struggled with the New York Mets after a January trade from Milwaukee, posting a 4.99 ERA across 22 starts before being dealt to the Rays at the 2026 trade deadline.
- The Rays moved Peralta to pitch exclusively from the stretch, shifted him to the third‑base side of the rubber, widened his stance, sped up his delivery, increased his changeup use, and added leg‑strength drills to his pregame routine.
- Those adjustments coincided with an immediate uptick in performance for Tampa Bay, including roughly a 3.25 ERA in a short post‑trade regular‑season run and a 0.79 ERA over 11.1 postseason innings capped by a six‑inning ALCS start.
- Mets president David Stearns acknowledged the club wanted similar changes but said New York was unable to get Peralta to implement them, and the Mets kept their major‑league pitching staff intact after the season.
- Peralta’s turnaround has boosted his trade and free‑agent appeal, with media coverage flagging likely offseason interest from teams seeking rotation upgrades and spotlighting the Rays’ methodical pitcher development process.
