Tanner Rainey is a relief pitcher for the Detroit Tigers. In 2026 he struck out 6 batters over 7.0 innings across 6 appearances, going 0-0. His ERA of 3.86 was 7.8% lower than the league average of 4.18. Stripping out defence, his 5.25 FIP suggests that his ERA had some help behind him. He missed bats on 39.5% of swings (13.4% of every pitch he threw), walked 25.8% of the batters he faced and struck out 19.4%. His -0.0 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.

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.
