Mets' David Peterson Grapples with Inconsistent Form, Manager Trusts Him for Next Start

New York Mets pitcher David Peterson continued his second-half struggles, allowing six runs in five innings during a recent 7-4 loss to the Padres on September 17, 2025. The outing, which included a Manny Machado grand slam, contributed to his 5.71 ERA over 11 starts since making his first All-Star team, a significant increase from his sub-3.00 ERA earlier in the season. Despite the inconsistency, manager Carlos Mendoza expressed trust in Peterson, stating, "We need him. He’s been a big part of this team." Mendoza confirmed Peterson will make his next start, emphasizing the team's need for him to return to his earlier ace-like form as they push for a playoff spot. Peterson acknowledged his struggles, noting, "It’s obviously tough when you know what you’re capable of."
