Jason Wheeler is a relief pitcher for the Minnesota Twins. In 2017 he struck out 0 batters over 3.0 innings across 2 appearances, going 0-0. His ERA of 9.00 was 106.5% higher than the league average of 4.36. Stripping out defence, his 11.49 FIP suggests that his ERA had some help behind him. He missed bats on 7.7% of swings (3.6% of every pitch he threw), walked 22.2% of the batters he faced and struck out 0.0%. His -0.2 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.
