Riley Cornelio is a relief pitcher for the Washington Nationals. In 2026 he struck out 20 batters over 20.0 innings across 11 appearances, going 2-1. His ERA of 5.40 was 29.3% higher than the league average of 4.18 — 11th of 15 on his team, and 389th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.74 FIP suggests he pitched better than his ERA shows. He missed bats on 31.7% of swings (15.4% of every pitch he threw), walked 20.8% of the batters he faced and struck out 20.8%. His -0.0 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.
