Jack O'Loughlin was a relief pitcher for the Oakland Athletics. In 2024 he struck out 6 batters over 9.2 innings across 4 appearances, going 0-0. His ERA of 4.66 was 14.1% higher than the league average of 4.08. Stripping out defence, his 4.82 FIP suggests the ERA was no fluke. He missed bats on 20.5% of swings (9.7% of every pitch he threw), walked 10.6% of the batters he faced and struck out 12.8%. 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.

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.
