Jay Flaa is a relief pitcher for the Atlanta Braves. In 2021 he struck out 3 batters over 2.2 innings across 2 appearances, going 0-0. His ERA of 13.50 was 216.5% higher than the league average of 4.27. Stripping out defence, his 14.05 FIP suggests that his ERA had some help behind him. He missed bats on 42.3% of swings (18.0% of every pitch he threw), walked 23.1% of the batters he faced and struck out 23.1%. His -0.3 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.
