Mike Johnston was a relief pitcher for the Pittsburgh Pirates. In 2005 he struck out 2 batters over 1.0 inning across 1 appearance, going 0-0. His ERA of 36.00 was 739.0% higher than the league average of 4.29. Stripping out defence, his 25.02 FIP suggests he pitched better than his ERA shows. He missed bats on 26.7% of swings (13.8% of every pitch he threw), walked 0.0% of the batters he faced and struck out 28.6%. 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.

Not in the 2005 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.

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.
