Riley Cornelio is a relief pitcher for the Washington Nationals. In 2026 he struck out 40 batters over 36.2 innings across 18 appearances, going 3-2. His ERA of 3.68 was 11.9% lower than the league average of 4.18 — 7th of 18 on his team, and 201st of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 4.00 FIP suggests that his ERA had some help behind him. He missed bats on 34.5% of swings (16.2% of every pitch he threw), walked 18.1% of the batters he faced and struck out 25.0%. 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.
