Luis Santos was a relief pitcher for the Toronto Blue Jays. In 2018 he struck out 24 batters over 20.0 innings across 15 appearances, going 1-1. His ERA of 7.20 was 73.5% higher than the league average of 4.15 — the worst on his team, and 511th of 530 among MLB pitchers with 20+ innings. Stripping out defence, his 5.01 FIP suggests he pitched better than his ERA shows. He missed bats on 33.7% of swings (15.6% of every pitch he threw), walked 11.0% of the batters he faced and struck out 26.4%. His -0.1 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.
