Ian Seymour is a relief pitcher for the Tampa Bay Rays. In 2026 he struck out 158 batters over 132.2 innings across 47 appearances, going 9-7. His ERA of 4.21 was 0.6% higher than the league average of 4.18 — 9th of 16 on his team, and 300th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 4.10 FIP suggests the ERA was no fluke. He missed bats on 29.4% of swings (15.2% of every pitch he threw), walked 6.5% of the batters he faced and struck out 28.7%. His 1.2 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.
