Mariners' Logan Evans Shows Extreme Pitching Splits in Rookie Season

Seattle Mariners pitcher Logan Evans displayed extreme splits in his rookie season, allowing a .529 OPS the first time through a lineup (5th best in MLB) but a 1.022 OPS the second time (worst). This .493 difference was the largest in 2025. Despite an overall 5.05 FIP in 15 starts, his deep six-pitch repertoire initially limited quality contact. However, all pitches worsened significantly after the lineup turn. Evans enters Spring Training 2026 as depth, expected to pitch in MLB, with the Mariners likely strategizing to extend his effectiveness deeper into games.
