Phillip Diehl is a relief pitcher for the Cincinnati Reds. In 2022 he struck out 3 batters over 5.2 innings across 5 appearances, going 0-0. His ERA of 11.12 was 180.2% higher than the league average of 3.97. Stripping out defence, his 10.52 FIP suggests he pitched better than his ERA shows. He missed bats on 23.2% of swings (10.8% of every pitch he threw), walked 10.7% of the batters he faced and struck out 10.7%. His -0.4 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.

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.
