Keith Hessler was a relief pitcher for the San Diego Padres. In 2016 he struck out 11 batters over 21.2 innings across 17 appearances, going 1-0. His ERA of 4.15 was 0.9% lower than the league average of 4.19 — 6th of 18 on his team, and 265th of 512 among MLB pitchers with 20+ innings. Stripping out defence, his 5.27 FIP suggests that his ERA had some help behind him. He missed bats on 17.2% of swings (7.4% of every pitch he threw), walked 12.6% of the batters he faced and struck out 10.7%. His -0.1 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.

Keith Hessler'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.
