Masahiro Tanaka was a starting pitcher for the New York Yankees. In 2020 he struck out 44 batters over 48.0 innings across 10 appearances, 10 of them starts, going 3-3. His ERA of 3.56 was 20.0% lower than the league average of 4.45 — 6th of 12 on his team, and 140th of 323 among MLB pitchers with 20+ innings. Stripping out defence, his 4.42 FIP suggests that his ERA had some help behind him. He missed bats on 29.7% of swings (15.3% of every pitch he threw), walked 4.1% of the batters he faced and struck out 22.3%. His 0.7 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.
