Ian Seymour is a relief pitcher for the Tampa Bay Rays. In 2026 he struck out 106 batters over 90.1 innings across 38 appearances, going 9-3. His ERA of 4.08 was 2.2% lower than the league average of 4.18 — 10th of 15 on his team, and 253rd of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 3.74 FIP suggests he pitched better than his ERA shows. He missed bats on 29.4% of swings (14.6% of every pitch he threw), walked 8.0% of the batters he faced and struck out 28.4%. His 1.0 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.
