Shintaro Fujinami is a relief pitcher for the Oakland Athletics. In 2023 he struck out 83 batters over 79.0 innings across 64 appearances, going 7-8. His ERA of 7.18 was 65.7% higher than the league average of 4.33 — the second worst on his team, and 533rd of 550 among MLB pitchers with 20+ innings. Stripping out defence, his 4.61 FIP suggests he pitched better than his ERA shows. He missed bats on 30.1% of swings (13.7% of every pitch he threw), walked 12.6% of the batters he faced and struck out 23.2%. 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.
