Juan Mateo was a starting pitcher for the Chicago Cubs. In 2006 he struck out 35 batters over 45.2 innings across 11 appearances, 10 of them starts, going 1-3. His ERA of 5.32 was 17.5% higher than the league average of 4.53 — 12th of 18 on his team, and 347th of 466 among MLB pitchers with 20+ innings. Stripping out defence, his 5.03 FIP suggests the ERA was no fluke. He missed bats on 16.5% of swings (7.7% of every pitch he threw), walked 11.0% of the batters he faced and struck out 16.7%. His 0.3 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.

Not in the 2006 data: pitch types, recorded in every park from 2008. The play-by-play goes back to 2005, but the measurements on each pitch and batted ball arrived later, so the panels built from them are left off this season.

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.
