Simon Castro is a relief pitcher for the Oakland Athletics. In 2017 he struck out 35 batters over 37.0 innings across 26 appearances, going 1-3. His ERA of 4.38 was level with the league average of 4.36 — 11th of 21 on his team, and 286th of 527 among MLB pitchers with 20+ innings. Stripping out defence, his 5.02 FIP suggests that his ERA had some help behind him. He missed bats on 18.0% of swings (7.9% of every pitch he threw), walked 9.2% of the batters he faced and struck out 22.9%. 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.
