Eric Hacker was a relief pitcher for the San Francisco Giants. In 2012 he struck out 8 batters over 9.2 innings across 4 appearances, going 0-1. His ERA of 5.59 was 39.1% higher than the league average of 4.01. Stripping out defence, his 5.06 FIP suggests he pitched better than his ERA shows. He missed bats on 22.4% of swings (10.6% of every pitch he threw), walked 4.4% of the batters he faced and struck out 17.8%. 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.

BAA and OPS are what hitters did against each pitch, credited to the one that ended the plate appearance, and are left blank under 15 at-bats.

How these are computed

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.
