Mets Call Up Jonah Tong and Will Keep Him in Rotation Through Season

The club plans to use his late Triple‑A rebound plus recent mechanical and pitch‑mix changes to judge whether he can be a 2027 rotation piece.

Overview

  • Tong will start Monday in Miami after interim manager Andy Green confirmed the promotion and said the Mets will continue to hand him starts for the rest of the year.
  • The roster move also sent reliever Jefry Yan to Triple‑A and brought Tobias Myers back to the big‑league bullpen.
  • The call‑up followed a marked turnaround at Triple‑A Syracuse in which Tong posted a 0.84 ERA with 23 strikeouts over his last four starts and took a no‑hitter into the seventh on Aug. 29.
  • Tong arrived in New York with deliberate changes to his delivery and repertoire — a lower arm slot, added cutter, refined curve and more changeups — though control and walk rate remain concerns from his earlier big‑league work.
  • The Mets, effectively out of contention, are treating these remaining starts as a structured audition to see if Tong’s adjustments translate to consistent major‑league success and a potential role in the 2027 rotation.
