Jacob Barnes was a relief pitcher for the Toronto Blue Jays. In 2025 he struck out 5 batters over 8.0 innings across 6 appearances, going 0-1. His ERA of 9.00 was 116.4% higher than the league average of 4.16. Stripping out defence, his 4.64 FIP suggests he pitched better than his ERA shows. He missed bats on 26.5% of swings (12.3% of every pitch he threw), walked 8.3% of the batters he faced and struck out 13.9%. 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.
