Shelby Miller is a relief pitcher for the Arizona Diamondbacks. In 2025 he struck out 54 batters over 46.0 innings across 48 appearances, going 4-3. His ERA of 2.74 was 34.1% lower than the league average of 4.16 — the third best on his team, and 86th of 542 among MLB pitchers with 20+ innings. Stripping out defence, his 3.44 FIP suggests that his ERA had some help behind him. He missed bats on 31.9% of swings (16.1% of every pitch he threw), walked 8.1% of the batters he faced and struck out 29.0%. His 0.6 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.
