John Foster was a relief pitcher for the Atlanta Braves. In 2005 he struck out 32 batters over 34.2 innings across 62 appearances, going 4-2. His ERA of 4.15 was 3.2% lower than the league average of 4.29 — 7th of 15 on his team, and 212th of 442 among MLB pitchers with 20+ innings. Stripping out defence, his 4.12 FIP suggests the ERA was no fluke. He missed bats on 22.0% of swings (8.6% of every pitch he threw), walked 12.7% of the batters he faced and struck out 21.3%. 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.

Opponent batting by the side the hitter bats from, 2005. Counted from play-by-play, so totals can differ from the box-score season line by a plate appearance or two.

Not in the 2005 data: pitch types, recorded in every park from 2008. The play-by-play goes back to 2005, but the measurements on each pitch and batted ball arrived later, so the panels built from them are left off this season.

How these are computed

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.
