Shelby Miller was 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 0.7 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.

Shelby Miller's arsenal by usage. Velocity is average release speed in mph, spin in rpm, and whiff rate is misses per swing — the cleanest single measure of whether a pitch beats hitters. BAA and OPS are what hitters did against each pitch, credited to the one that ended the plate appearance, and are left blank under 15 at-bats.

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.
