Ryan Thompson is a relief pitcher for the Arizona Diamondbacks. In 2026 he struck out 29 batters over 40.2 innings across 46 appearances, going 4-2. His ERA of 4.43 was 5.9% higher than the league average of 4.18 — 9th of 16 on his team, and 330th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 3.82 FIP suggests he pitched better than his ERA shows. He missed bats on 19.2% of swings (9.3% of every pitch he threw), walked 7.0% of the batters he faced and struck out 15.6%. 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.

Box-score and rate statistics only. wOBA, wRC+, FIP and dbWAR are measured against a full league season, and a postseason is a few teams playing each other for a month, so they are not computed for October.

Ryan Thompson'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.
