Glenn Otto Jr. was a relief pitcher for the Texas Rangers. In 2023 he struck out 11 batters over 10.2 innings across 6 appearances, going 0-0. His ERA of 10.13 was 133.7% higher than the league average of 4.33. Stripping out defence, his 10.19 FIP suggests the ERA was no fluke. He missed bats on 33.3% of swings (16.7% of every pitch he threw), walked 11.8% of the batters he faced and struck out 21.6%. His -0.6 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.
