Roberto Osuna was a relief pitcher for the Houston Astros. In 2020 he struck out 3 batters over 4.1 innings across 4 appearances, going 0-0. His ERA of 2.08 was 53.4% lower than the league average of 4.45. Stripping out defence, his 1.81 FIP suggests the ERA was no fluke. He missed bats on 28.6% of swings (14.8% of every pitch he threw), walked 0.0% of the batters he faced and struck out 18.8%. His 0.2 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.

Roberto Osuna'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.
