Seth Maness was a relief pitcher for the Kansas City Royals. In 2017 he struck out 4 batters over 9.2 innings across 8 appearances, going 1-0. His ERA of 3.72 was 14.5% lower than the league average of 4.36. Stripping out defence, his 6.99 FIP suggests that his ERA had some help behind him. He missed bats on 12.2% of swings (5.5% of every pitch he threw), walked 4.4% of the batters he faced and struck out 8.9%. His -0.2 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.
