Jason Frasor is a relief pitcher for the Kansas City Royals. In 2015 he struck out 22 batters over 28.0 innings across 32 appearances, going 1-0. His ERA of 1.29 was 67.5% lower than the league average of 3.96 — the second best on his team, and 6th of 513 among MLB pitchers with 20+ innings. Stripping out defence, his 3.96 FIP suggests that his ERA had some help behind him. He missed bats on 19.8% of swings (8.8% of every pitch he threw), walked 14.5% of the batters he faced and struck out 17.7%. His 0.2 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.
