Chase Petty is a relief pitcher for the Cincinnati Reds. In 2026 he struck out 15 batters over 31.2 innings across 16 appearances, going 1-2. His ERA of 4.83 was 15.6% higher than the league average of 4.18 — 11th of 20 on his team, and 383rd of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 5.76 FIP suggests that his ERA had some help behind him. He missed bats on 19.6% of swings (9.4% of every pitch he threw), walked 6.5% of the batters he faced and struck out 10.8%. 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.
