Jordan Leasure is a relief pitcher for the Chicago White Sox. In 2026 he struck out 18 batters over 18.2 innings across 18 appearances, going 2-1. His ERA of 6.27 was 49.9% higher than the league average of 4.18. Stripping out defence, his 6.64 FIP suggests that his ERA had some help behind him. He missed bats on 26.5% of swings (13.7% of every pitch he threw), walked 10.3% of the batters he faced and struck out 23.1%. 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.
