Orion Kerkering is a relief pitcher for the Philadelphia Phillies. In 2026 he struck out 51 batters over 46.1 innings across 51 appearances, going 6-1. His ERA of 3.88 was 7.0% lower than the league average of 4.18 — 7th of 16 on his team, and 235th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 3.67 FIP suggests the ERA was no fluke. He missed bats on 27.3% of swings (11.8% of every pitch he threw), walked 12.6% of the batters he faced and struck out 24.8%. His 0.5 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.
