Mike Vasil is a relief pitcher for the Chicago White Sox. In 2025 he struck out 82 batters over 101.0 innings across 47 appearances, going 5-3. His ERA of 2.50 was 40.0% lower than the league average of 4.16 — the second best on his team, and 59th of 542 among MLB pitchers with 20+ innings. Stripping out defence, his 4.32 FIP suggests that his ERA had some help behind him. He missed bats on 24.0% of swings (10.2% of every pitch he threw), walked 12.3% of the batters he faced and struck out 19.4%. His 0.4 dbWAR is built from that FIP rather than runs allowed, so it credits him for what he controls and not for the defence behind him.
