Ruben Sierra was a designated hitter for the Minnesota Twins. In 2006 he hit 0 home runs and knocked in 4 RBIs, notching 5 hits across 33 plate appearances in 14 games. His batting average was .179, 33.7% lower than the league average of .269. He reached base at a .273 clip and slugged .214, for an OPS of .487, 36.6% lower than the league mark of .768. He made contact on 73.6% of his swings. Adjusted for his ballpark and league, his 32 wRC+ puts his offence 68% below average. That comes to -0.2 dbWAR — -2.8 runs with the bat, +0.0 for the ballpark, -0.0 on the bases, +0.3 on double plays, -0.8 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.
League context
Percentile among qualified batters, 2006 regular season.
How the WAR is built
Runs above replacement, 2006. These terms sum to -2.3 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.

How Ruben Sierra hits by base state, outs, score and late-game pressure — each read against his own season line.

Runners on includes runners in scoring position, which is the convention every reference uses. Rows under 25 plate appearances are marked thin — at that size a rate moves several dozen points on one hit. Counted from play-by-play, 2006.
Not in the 2006 data: pitch locations, first recorded in 2007; 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.
