Mitchell Parker is a relief pitcher for the Washington Nationals. In 2026 he struck out 34 batters over 39.2 innings across 22 appearances, going 3-3. His ERA of 6.58 was 57.6% higher than the league average of 4.18 — the second worst on his team, and 440th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 5.46 FIP suggests he pitched better than his ERA shows. He missed bats on 28.1% of swings (14.2% of every pitch he threw), walked 7.3% of the batters he faced and struck out 19.1%. 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.
