JoJo Romero is a relief pitcher for the St. Louis Cardinals. In 2026 he struck out 54 batters over 56.1 innings across 55 appearances, going 3-3. His ERA of 3.04 was 27.4% lower than the league average of 4.18 — the second best on his team, and 98th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 3.97 FIP suggests that his ERA had some help behind him. He missed bats on 22.1% of swings (9.2% of every pitch he threw), walked 7.6% of the batters he faced and struck out 22.7%. 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.
