The Chicago Cubs recently brought in left-handed pitcher David Peterson via a trade with the New York Mets, hoping a new environment can help him regain his form. Peterson has had a difficult season, but he was an All-Star in 2025 and believes he’s capable of returning to that level with Chicago.
Peterson said he’s excited about the opportunity, even if the trade initially caught him off guard. He emphasized that he feels healthy and explained that he dealt with some early-season issues that needed to be corrected. Now, he says he feels more like the pitcher he was in 2024 and 2025.
If Peterson truly recaptures his 2025 form, the move could prove to be a steal for the Cubs. While he wasn’t dominant during his All-Star campaign, finishing with a 4.22 ERA, he was dependable and took the ball consistently. He was even more effective the year before, posting a strong 2.90 ERA across 21 appearances.
Chicago’s biggest need right now is pitching depth. Injuries have ravaged the rotation, and even if Peterson isn’t at his peak, he should still provide valuable innings. Ideally for the Cubs, he’ll do more than just fill a spot and deliver quality performances.
The Cubs enter Friday night’s game against Milwaukee with a 44–37 record, trailing by 6.5 games in the National League Central race. Colin Rea is scheduled to start Friday’s matchup, while Peterson is expected to make his Cubs debut on Saturday night in Milwaukee.
