Rubby De La Rosa was a relief pitcher for the Arizona Diamondbacks. In 2017 he struck out 12 batters over 7.2 innings across 9 appearances, going 0-1. His ERA of 4.70 was 7.7% higher than the league average of 4.36. Stripping out defence, his 4.98 FIP suggests the ERA was no fluke. He missed bats on 39.4% of swings (20.8% of every pitch he threw), walked 11.8% of the batters he faced and struck out 35.3%. 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.
