Jeff Niemann was a starting pitcher for the Tampa Bay Rays. In 2012 he struck out 34 batters over 38.0 innings across 8 appearances, 8 of them starts, going 2-3. His ERA of 3.08 was 23.3% lower than the league average of 4.01 — 8th of 15 on his team, and 130th of 484 among MLB pitchers with 20+ innings. Stripping out defence, his 3.09 FIP suggests the ERA was no fluke. He missed bats on 25.0% of swings (10.7% of every pitch he threw), walked 7.7% of the batters he faced and struck out 21.8%. His 0.8 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.
