Overview
- The Mets traded left-hander David Peterson to the Chicago Cubs on Thursday, June 25, 2026, and received 22-year-old corner‑infielder Cole Mathis as the sole return.
- Peterson has struggled this season, carrying a 6.09 ERA, and his departure ends his run as the longest‑tenured Met on the roster.
- Cole Mathis is a 2024 second‑round pick who hit .272 with a .981 OPS across Single‑A and High‑A in 2026, has shown power with 10 homers in 39 games, and is currently recovering from an injury.
- New York also reinstated Francisco Lindor from the 10‑day injured list, designated Zack Short for assignment to clear a roster spot, optioned Ronny Mauricio to Triple‑A Syracuse, and manager Carlos Mendoza announced Kodai Senga will move to the bullpen.
- The deal removes a struggling starter before free agency, gives the Mets a low‑minors bat to evaluate if he heals, and could reshape the club’s near‑term rotation depth and prospect timeline depending on Mathis’s recovery and Senga’s role change.
