Mitch Keller is a starting pitcher for the Pittsburgh Pirates. In 2026 he struck out 89 batters over 115.2 innings across 22 appearances, 22 of them starts, going 6-8. His ERA of 5.29 was 26.5% higher than the league average of 4.18 — 12th of 15 on his team, and 429th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 4.55 FIP suggests he pitched better than his ERA shows. He missed bats on 20.5% of swings (9.7% of every pitch he threw), walked 8.3% of the batters he faced and struck out 17.7%. His 1.0 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.
