Mets not ready for rotation shakeup despite inconsistent David Peterson

Even after David Peterson allowed five runs in the first two innings of Wednesday afternoon’s 7-2 loss to the Arizona Diamondbacks, it would be fair to say the New York Mets starting rotation has largely inspired confidence this season. Only five teams’ rotations have struck out more batters, and two of them have played a full game more than the Mets had as of late Wednesday evening. Nolan McLean has looked ace-ready.

Kodai Senga has pitched with more power than he did in 2025. Freddy Peralta has yet to be at his best, and he has still been very good. But if cracks are going to spread – and when it comes to major league starting pitching, they almost always do – Wednesday offered a glimpse into where they might find room.

After allowing a run on two hits in the first, Peterson was vexed with small ball and pummeled with hits in a four-run second inning before retiring 11 of the last 12 batters he faced. Inconsistency, not total ineffectiveness, has been his undoing: Since he worked in and out of traffic through 5. 1 scoreless innings in his first start of the year, Peterson has allowed 10 runs over 9.

1 innings in his last two, scattering 15 hits and four walks. His ERA is 6. 14.
