Kevin Kelly is a relief pitcher for the Tampa Bay Rays. In 2026 he struck out 43 batters over 54.0 innings across 50 appearances, going 5-3. His ERA of 2.00 was 52.1% lower than the league average of 4.18 — the second best on his team, and 18th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 3.12 FIP suggests that his ERA had some help behind him. He missed bats on 19.4% of swings (9.3% of every pitch he threw), walked 4.5% of the batters he faced and struck out 21.5%. His 0.9 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.

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.
