Antonio Alfonseca was a relief pitcher for the Philadelphia Phillies. In 2007 he struck out 24 batters over 49.2 innings across 61 appearances, going 5-2. His ERA of 5.44 was 21.5% higher than the league average of 4.47 — 11th of 17 on his team, and 362nd of 484 among MLB pitchers with 20+ innings. Stripping out defence, his 4.75 FIP suggests he pitched better than his ERA shows. He missed bats on 16.3% of swings (7.5% of every pitch he threw), walked 11.4% of the batters he faced and struck out 10.2%. 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.
