John King is a relief pitcher for the Miami Marlins. In 2026 he struck out 33 batters over 47.0 innings across 47 appearances, going 6-2. His ERA of 3.06 was 26.6% lower than the league average of 4.18 — 4th of 16 on his team, and 108th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.43 FIP suggests that his ERA had some help behind him. He missed bats on 21.9% of swings (10.4% of every pitch he threw), walked 7.2% of the batters he faced and struck out 18.3%. 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.
