Tyler Uberstine is a relief pitcher for the Boston Red Sox. In 2026 he struck out 2 batters over 2.2 innings across 1 appearance, going 0-1. His ERA of 3.38 was 19.2% lower than the league average of 4.18. Stripping out defence, his 7.59 FIP suggests that his ERA had some help behind him. He missed bats on 30.8% of swings (17.8% of every pitch he threw), walked 9.1% of the batters he faced and struck out 18.2%. 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.

Head to head
Put Tyler Uberstine 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.
