Alfredo Aceves was a relief pitcher for the New York Yankees. In 2014 he struck out 16 batters over 19.1 innings across 10 appearances, going 1-2. His ERA of 6.52 was 74.2% higher than the league average of 3.74. Stripping out defence, his 6.29 FIP suggests the ERA was no fluke. He missed bats on 22.4% of swings (10.8% of every pitch he threw), walked 4.7% of the batters he faced and struck out 18.8%. 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.

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.
