Tommy Manzella was a shortstop for the Houston Astros. In 2010 he hit 1 home run and knocked in 21 RBIs, notching 58 hits across 282 plate appearances in 79 games. His batting average was .225, 12.6% lower than the league average of .257. He reached base at a .267 clip and slugged .264, for an OPS of .531, 27.1% lower than the league mark of .728 — the worst on his team, and 430th of 442 among MLB batters with 100+ plate appearances. He made contact on 75.6% of his swings. Adjusted for his ballpark and league, his 44 wRC+ puts his offence 56% below average. That comes to -0.7 dbWAR — -18.6 runs with the bat, +0.6 for the ballpark, -0.6 on the bases, +0.2 on double plays, +3.8 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.

Runners on includes runners in scoring position, which is the convention every reference uses. Counted from play-by-play, 2010.
Not in the 2010 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.
