Shinnosuke Ogasawara was a relief pitcher for the Washington Nationals. In 2025 he struck out 30 batters over 38.2 innings across 23 appearances, going 1-1. His ERA of 6.98 was 67.9% higher than the league average of 4.16 — 18th of 21 on his team, and 515th of 542 among MLB pitchers with 20+ innings. Stripping out defence, his 6.16 FIP suggests he pitched better than his ERA shows. He missed bats on 23.5% of swings (10.7% of every pitch he threw), walked 9.8% of the batters he faced and struck out 17.3%. His -0.6 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.
