David Peterson failed in his last chance with the Mets

Grace Carbone writes that David Peterson struggled heavily during his final campaign with the New York Mets before being traded to the Chicago Cubs on June 25, 2026. Prior to the trade, the left-handed pitcher posted a career-worst 6.09 ERA, a 1.647 WHIP, and -1.0 bWAR across 16 appearances for New York.

The Mets acquired minor league first baseman Cole Mathis in exchange for Peterson, who subsequently improved in Chicago by recording a 3.70 ERA across 16 games. Despite past achievements such as an All-Star nod in 2025 and key 2024 postseason moments, Carbone argues that Peterson's tenure ended with disappointment as he heads into MLB free agency.
