Mike Mayers was a relief pitcher for the Kansas City Royals. In 2023 he struck out 17 batters over 26.1 innings across 6 appearances, going 1-2. His ERA of 6.15 was 42.0% higher than the league average of 4.33 — 21st of 23 on his team, and 488th of 550 among MLB pitchers with 20+ innings. Stripping out defence, his 5.08 FIP suggests he pitched better than his ERA shows. He missed bats on 19.5% of swings (9.2% of every pitch he threw), walked 8.4% of the batters he faced and struck out 14.3%. 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.
