The New York Mets replaced David Peterson with Sean Manaea in their starting rotation, according to the team’s May 27 announcement. Manager Carlos Mendoza confirmed the change ahead of their upcoming game in Seattle.
What happened
The Mets will depend on Sean Manaea for crucial innings. Mendoza remarked that Peterson’s demotion serves the team’s best interests. Manaea may start on May 29 or serve as a bulk reliever in a game.
Peterson, an All-Star last season, struggled, finishing 2025 with an 8.42 ERA in his last outings. In four starts this season, he posted a 6.41 ERA. Following a poor performance against the Cincinnati Reds on May 26, where he allowed six runs, team officials chose to reassess his role.
Why it matters
This rotation change could impact the Mets’ playoff aspirations significantly. With Manaea stepping in, the team needs consistent starting pitching to navigate upcoming contests effectively.
Background
After a brief demotion of Peterson on April 22, the Mets called up Christian Scott to take his place. However, following a lackluster debut from Scott, Peterson returned but continued to face challenges. Despite a 2.50 ERA over his first four outings in May, persistent inconsistencies led to the decision for his replacement.
What's next
The Mets’ rotation will now include Freddy Peralta, Christian Scott, Nolan McLean, and Manaea. Kodai Senga, currently sidelined with a back injury, may return next month if his Minor League rehab proves successful.
