Sean Reynolds is a relief pitcher for the San Diego Padres. In 2025 he struck out 25 batters over 27.0 innings across 19 appearances, going 0-1. His ERA of 5.33 was 28.3% higher than the league average of 4.16 — 15th of 18 on his team, and 435th of 542 among MLB pitchers with 20+ innings. Stripping out defence, his 5.43 FIP suggests the ERA was no fluke. He missed bats on 22.7% of swings (9.7% of every pitch he threw), walked 14.5% of the batters he faced and struck out 21.4%. 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.

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.
