Tony Gonsolin is a relief pitcher for the Kansas City Royals. In 2026 he struck out 5 batters over 2.2 innings across 1 appearance, going 0-0. His ERA of 16.88 is 303.9% higher than the league average of 4.18. Stripping out defence, his 7.60 FIP suggests he pitched better than his ERA shows. He missed bats on 27.3% of swings (9.5% of every pitch he threw), walked 20.0% of the batters he faced and struck out 33.3%. His -0.1 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.
