Michael Tonkin was a relief pitcher for the Minnesota Twins. In 2025 he struck out 19 batters over 24.0 innings across 21 appearances, going 2-1. His ERA of 4.88 was 17.2% higher than the league average of 4.16 — 12th of 21 on his team, and 401st of 542 among MLB pitchers with 20+ innings. Stripping out defence, his 4.80 FIP suggests the ERA was no fluke. He missed bats on 20.7% of swings (9.1% of every pitch he threw), walked 7.8% of the batters he faced and struck out 18.4%. His -0.0 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.
