Spencer Turnbull was a relief pitcher for the Toronto Blue Jays. In 2025 he struck out 4 batters over 6.1 innings across 3 appearances, going 1-1. His ERA of 7.11 was 70.9% higher than the league average of 4.16. Stripping out defence, his 5.82 FIP suggests he pitched better than his ERA shows. He missed bats on 25.4% of swings (12.0% of every pitch he threw), walked 12.1% of the batters he faced and struck out 12.1%. His -0.1 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.

Spencer Turnbull'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.
