Grant Balfour was a relief pitcher for the Tampa Bay Rays. In 2015 he struck out 0 batters over 4.1 innings across 6 appearances, going 0-0. His ERA of 6.23 was 57.3% higher than the league average of 3.96. Stripping out defence, his 9.60 FIP suggests that his ERA had some help behind him. He missed bats on 18.2% of swings (6.7% of every pitch he threw), walked 19.0% of the batters he faced and struck out 0.0%. His -0.3 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.
