John King is a relief pitcher for the Miami Marlins. In 2026 he struck out 33 batters over 49.2 innings across 50 appearances, going 6-2. His ERA of 3.99 was 4.7% lower than the league average of 4.18 — 11th of 18 on his team, and 261st of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 4.88 FIP suggests that his ERA had some help behind him. He missed bats on 21.7% of swings (10.2% of every pitch he threw), walked 8.6% of the batters he faced and struck out 16.8%. His -0.1 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.
