Brandon Duckworth was a starting pitcher for the Kansas City Royals. In 2008 he struck out 20 batters over 38.0 innings across 7 appearances, 7 of them starts, going 3-3. His ERA of 4.50 was 4.1% higher than the league average of 4.32 — 10th of 16 on his team, and 277th of 482 among MLB pitchers with 20+ innings. Stripping out defence, his 4.50 FIP suggests the ERA was no fluke. He missed bats on 16.2% of swings (7.1% of every pitch he threw), walked 11.4% of the batters he faced and struck out 12.0%. 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.

Brandon Duckworth'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.
