Dellin Betances was a relief pitcher for the New York Mets. In 2021 he struck out 1 batter over 1.0 inning across 1 appearance, going 0-0. His ERA of 9.00 was 111.0% higher than the league average of 4.27. Stripping out defence, his 7.17 FIP suggests he pitched better than his ERA shows. He missed bats on 16.7% of swings (4.8% of every pitch he threw), walked 20.0% of the batters he faced and struck out 20.0%. His -0.0 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.

Dellin Betances'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.
