Joe Mantiply is a relief pitcher for the Toronto Blue Jays. In 2026 he struck out 22 batters over 27.0 innings across 25 appearances, going 2-0. His ERA of 3.33 is 20.2% lower than the league average of 4.18 — 6th of 16 on his team, and 134th of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 3.58 FIP suggests the ERA was no fluke. He missed bats on 16.8% of swings (8.3% of every pitch he threw), walked 4.5% of the batters he faced and struck out 19.8%. 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.
