Dustin Richardson was a relief pitcher for the Boston Red Sox. In 2010 he struck out 12 batters over 13.0 innings across 26 appearances, going 0-0. His ERA of 4.15 was 1.8% higher than the league average of 4.08. Stripping out defence, his 6.69 FIP suggests that his ERA had some help behind him. He missed bats on 19.5% of swings (7.5% of every pitch he threw), walked 20.9% of the batters he faced and struck out 17.9%. 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.

Dustin Richardson's arsenal by usage. Velocity is average release speed in mph, spin in rpm, and whiff rate is misses per swing — the cleanest single measure of whether a pitch beats hitters. BAA and OPS are what hitters did against each pitch, credited to the one that ended the plate appearance, and are left blank under 15 at-bats.

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.
