Joel Peralta was a relief pitcher for the Seattle Mariners. In 2016 he struck out 33 batters over 27.1 innings across 31 appearances, going 1-1. His ERA of 5.93 was 41.5% higher than the league average of 4.19 — the second worst on his team, and 449th of 512 among MLB pitchers with 20+ innings. Stripping out defence, his 6.00 FIP suggests the ERA was no fluke. He missed bats on 27.1% of swings (13.8% of every pitch he threw), walked 6.7% of the batters he faced and struck out 27.7%. 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.

Joel Peralta'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.
