Nolan McLean Continues Impressive Rookie Season, Makes MLB History for Mets

New York Mets rookie Nolan McLean continues to impress, carrying the team's rotation since his major league debut last month. In his latest outing on September 21, 2025, against the Nationals, McLean's spotless Citi Field ERA received its first blemishes due to defensive miscues, leading to a frustrating 5-3 loss. Despite allowing three runs, only one was earned, as he completed five innings with six strikeouts on 92 pitches. McLean entered the weekend with a pristine 1.19 ERA, the lowest through six starts in Mets history, and now holds a 1.27 ERA through seven appearances. Manager Carlos Mendoza praised his "really good" stuff. The 24-year-old also made MLB history, becoming only the second pitcher ever to record 45-plus strikeouts with six or fewer runs allowed across his first seven big league outings, showcasing ace-level potential. He is slated for one final regular-season start against the Marlins.
