Justin Sterner is a relief pitcher for the Athletics. In 2026 he struck out 40 batters over 42.2 innings across 46 appearances, going 2-3. His ERA of 6.12 was 46.5% higher than the league average of 4.18 — 13th of 16 on his team, and 424th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 5.48 FIP suggests he pitched better than his ERA shows. He missed bats on 29.9% of swings (15.6% of every pitch he threw), walked 7.1% of the batters he faced and struck out 21.7%. 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.
