Scouting Report: Sean Manaea

Summary

Sean Manaea, a left-handed pitcher for the New York Mets, is experiencing a significant performance decline in 2026. Operating as a reliever, he owns a 6.85 ERA across 8 appearances with 24 strikeouts in 22.1 innings pitched. His peripherals are concerning with a .312 batting average against and 1.75 WHIP, both career worsts. Recent outings have been particularly troubling, including a disastrous 2.2-inning appearance against Washington (6 ER on 7 hits, 2 walks, 1 HBP) and a brief ninth-inning collapse against Colorado (1 out, 3 hits, 1 HBP). Notably, he has hit a batter in each of his last three relief appearances. However, there was a positive sign in a recent appearance against Arizona where he pitched a scoreless eighth inning with 2 strikeouts and showed improved velocity (91.3 mph average on his four-seamer, up from 89.7 mph). Manager Carlos Mendoza has expressed confidence in Manaea's ability and stated the coaching staff is "really digging in" to help him recover form. Mendoza emphasized that Manaea is "too good of a pitcher" and "very important" to the team's plans.
