Orion Kerkering is a relief pitcher for the Philadelphia Phillies. In 2026 he struck out 63 batters over 58.0 innings across 63 appearances, going 7-1. His ERA of 4.97 is 18.9% higher than the league average of 4.18 — 11th of 17 on his team, and 406th of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 4.17 FIP suggests he pitched better than his ERA shows. He missed bats on 26.1% of swings (11.0% of every pitch he threw), walked 12.7% of the batters he faced and struck out 23.5%. 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.
