Jayson Aquino was a relief pitcher for the Baltimore Orioles. In 2017 he struck out 13 batters over 13.1 innings across 4 appearances, going 1-2. His ERA of 7.42 was 70.4% higher than the league average of 4.36. Stripping out defence, his 6.46 FIP suggests he pitched better than his ERA shows. He missed bats on 26.9% of swings (11.8% of every pitch he threw), walked 9.7% of the batters he faced and struck out 21.0%. 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.

Head to head
Put Jayson Aquino beside up to three others.
wOBA uses linear weights measured from this season's own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page.
