Ron Marinaccio is a relief pitcher for the San Diego Padres. In 2026 he struck out 43 batters over 54.1 innings across 38 appearances, going 1-0. His ERA of 5.13 was 23.0% higher than the league average of 4.18 — 14th of 18 on his team, and 361st of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 5.39 FIP suggests the ERA was no fluke. He missed bats on 25.5% of swings (12.3% of every pitch he threw), walked 8.9% of the batters he faced and struck out 18.1%. His -0.5 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.
