Clay Buchholz was a starting pitcher for the Toronto Blue Jays. In 2019 he struck out 39 batters over 59.0 innings across 12 appearances, 12 of them starts, going 2-5. His ERA of 6.56 was 45.6% higher than the league average of 4.51 — the second worst on his team, and 489th of 545 among MLB pitchers with 20+ innings. Stripping out defence, his 5.62 FIP suggests he pitched better than his ERA shows. He missed bats on 20.6% of swings (9.8% of every pitch he threw), walked 6.3% of the batters he faced and struck out 15.4%. 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.

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.
