Kohei Arihara was a starting pitcher for the Texas Rangers. In 2022 he struck out 14 batters over 20.0 innings across 5 appearances, 4 of them starts, going 1-3. His ERA of 9.45 was 138.1% higher than the league average of 3.97 — the worst on his team, and the second worst among MLB pitchers with 20+ innings. Stripping out defence, his 6.41 FIP suggests he pitched better than his ERA shows. He missed bats on 21.6% of swings (10.3% of every pitch he threw), walked 10.2% of the batters he faced and struck out 13.0%. 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.
