Sean Casey was a first baseman for the Boston Red Sox. In 2008 he hit 0 home runs and knocked in 17 RBIs, notching 64 hits across 218 plate appearances in 67 games. His batting average was .322, 21.9% higher than the league average of .264. He reached base at a .381 clip and slugged .392, for an OPS of .773, 3.1% higher than the league mark of .749 — 7th of 14 on his team, and 166th of 447 among MLB batters with 100+ plate appearances. He made contact on 88.5% of his swings. Adjusted for his ballpark and league, his 107 wRC+ puts his offence 7% above average. That comes to 0.5 dbWAR — +2.5 runs with the bat, -0.3 for the ballpark, +0.0 on the bases, -0.5 on double plays, -3.4 for the position he plays, against replacement level. It includes no fielding: defensive runs are proprietary and are not estimated here, so the figure credits playing a demanding position but not playing it well.

How the WAR is built
Runs above replacement, 2008. These terms sum to +4.5 runs, divided by runs-per-win to give WAR. There is no fielding term.

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.

Runners on includes runners in scoring position, which is the convention every reference uses. Counted from play-by-play, 2008.
Not in the 2008 data: exit velocity and launch angle, first recorded in 2015. 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.

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.
