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.
