Bobby Jenks was a relief pitcher for the Boston Red Sox. In 2011 he struck out 17 batters over 15.2 innings across 19 appearances, going 2-2. His ERA of 6.32 was 60.3% higher than the league average of 3.94. Stripping out defence, his 4.17 FIP suggests he pitched better than his ERA shows. He missed bats on 23.6% of swings (10.0% of every pitch he threw), walked 16.3% of the batters he faced and struck out 21.3%. 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.

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.
