Andrew Saalfrank is a relief pitcher for the Arizona Diamondbacks. In 2025 he struck out 19 batters over 29.0 innings across 28 appearances, going 2-1. His ERA of 1.24 was 70.1% lower than the league average of 4.16 — the best on his team, and the second best among MLB pitchers with 20+ innings. Stripping out defence, his 3.31 FIP suggests that his ERA had some help behind him. He missed bats on 27.9% of swings (13.1% of every pitch he threw), walked 8.8% of the batters he faced and struck out 16.8%. His 0.4 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.
