Daniel Stumpf is a relief pitcher for the Detroit Tigers. In 2019 he struck out 28 batters over 29.0 innings across 48 appearances, going 1-1. His ERA of 4.34 was 3.6% lower than the league average of 4.51 — 5th of 21 on his team, and 246th of 545 among MLB pitchers with 20+ innings. Stripping out defence, his 5.08 FIP suggests that his ERA had some help behind him. He missed bats on 24.9% of swings (11.1% of every pitch he threw), walked 11.1% of the batters he faced and struck out 20.7%. 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.

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.
