Anthony DeSclafani is a relief pitcher for the Arizona Diamondbacks. In 2025 he struck out 36 batters over 38.2 innings across 13 appearances, going 1-2. His ERA of 5.12 was 23.1% higher than the league average of 4.16 — 14th of 18 on his team, and 425th of 542 among MLB pitchers with 20+ innings. Stripping out defence, his 6.29 FIP suggests that his ERA had some help behind him. He missed bats on 25.9% of swings (12.1% of every pitch he threw), walked 7.1% of the batters he faced and struck out 21.3%. 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.
