Ariel Hernández was a relief pitcher for the Cincinnati Reds. In 2017 he struck out 29 batters over 24.1 innings across 19 appearances, going 0-0. His ERA of 5.18 was 18.8% higher than the league average of 4.36 — 14th of 22 on his team, and 396th of 527 among MLB pitchers with 20+ innings. Stripping out defence, his 6.69 FIP suggests that his ERA had some help behind him. He missed bats on 32.0% of swings (12.9% of every pitch he threw), walked 20.4% of the batters he faced and struck out 26.9%. His -0.5 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.
