Mitch Spence is a relief pitcher for the Kansas City Royals. In 2026 he struck out 6 batters over 9.1 innings across 3 appearances, going 0-2. His ERA of 21.21 was 408.0% higher than the league average of 4.18. Stripping out defence, his 8.87 FIP suggests he pitched better than his ERA shows. He missed bats on 20.0% of swings (9.0% of every pitch he threw), walked 16.1% of the batters he faced and struck out 10.7%. 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.

Head to head
Put Mitch Spence beside up to three others.
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.
