Jon Lieber was a relief pitcher for the Chicago Cubs. In 2008 he struck out 27 batters over 46.2 innings across 26 appearances, going 2-3. His ERA of 4.05 was 6.3% lower than the league average of 4.32 — 8th of 15 on his team, and 209th of 482 among MLB pitchers with 20+ innings. Stripping out defence, his 5.27 FIP suggests that his ERA had some help behind him. He missed bats on 22.8% of swings (11.8% of every pitch he threw), walked 2.9% of the batters he faced and struck out 13.2%. 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.

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.
