Riley Cornelio is a relief pitcher for the Washington Nationals. In 2026 he struck out 38 batters over 34.2 innings across 17 appearances, going 3-2. His ERA of 3.89 is 6.8% lower than the league average of 4.18 — 10th of 18 on his team, and 243rd of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 4.08 FIP suggests the ERA was no fluke. He missed bats on 34.8% of swings (16.5% of every pitch he threw), walked 18.3% of the batters he faced and struck out 24.8%. 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.
