Jason Grilli was a relief pitcher for the Toronto Blue Jays. In 2017 he struck out 48 batters over 40.0 innings across 46 appearances, going 2-5. His ERA of 6.30 was 44.6% higher than the league average of 4.36 — 13th of 17 on his team, and 471st of 527 among MLB pitchers with 20+ innings. Stripping out defence, his 6.08 FIP suggests the ERA was no fluke. He missed bats on 25.8% of swings (12.5% of every pitch he threw), walked 9.8% of the batters he faced and struck out 26.1%. His -0.6 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.

Box-score and rate statistics only. wOBA, wRC+, FIP and dbWAR are measured against a full league season, and a postseason is a few teams playing each other for a month, so they are not computed for October.

Jason Grilli'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.
