Joe Thatcher is a relief pitcher for the Houston Astros. In 2015 he struck out 26 batters over 22.2 innings across 43 appearances, going 1-3. His ERA of 3.18 was 19.8% lower than the league average of 3.96 — 5th of 15 on his team, and 134th of 513 among MLB pitchers with 20+ innings. Stripping out defence, his 3.00 FIP suggests the ERA was no fluke. He missed bats on 27.1% of swings (12.4% of every pitch he threw), walked 12.0% of the batters he faced and struck out 26.0%. His 0.4 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.
