JoJo Romero is a relief pitcher for the St. Louis Cardinals. In 2026 he struck out 43 batters over 43.0 innings across 44 appearances, going 1-3. His ERA of 3.35 was 19.8% lower than the league average of 4.18 — the third best on his team, and 141st of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 3.99 FIP suggests that his ERA had some help behind him. He missed bats on 23.6% of swings (9.4% of every pitch he threw), walked 8.6% of the batters he faced and struck out 23.1%. His 0.3 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.
