Kevin Kelly is a relief pitcher for the Tampa Bay Rays. In 2026 he struck out 63 batters over 73.2 innings across 71 appearances, going 6-4. His ERA of 2.44 was 41.6% lower than the league average of 4.18 — the third best on his team, and 41st of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 3.02 FIP suggests that his ERA had some help behind him. He missed bats on 24.0% of swings (11.9% of every pitch he threw), walked 3.9% of the batters he faced and struck out 22.6%. His 1.4 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.

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.

Kevin Kelly'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.
