Mark DeRosa was a third baseman for the Toronto Blue Jays. In 2013 he hit 7 home runs and knocked in 36 RBIs, notching 48 hits across 236 plate appearances in 88 games. His batting average was .235, 7.2% lower than the league average of .253. He reached base at a .326 clip and slugged .407, for an OPS of .733, 2.7% higher than the league mark of .714 — 7th of 18 on his team, and 175th of 453 among MLB batters with 100+ plate appearances. He made contact on 70.1% of his swings. Adjusted for his ballpark and league, his 103 wRC+ puts his offence 3% above average. That comes to 0.6 dbWAR — +1.7 runs with the bat, -0.4 for the ballpark, -0.2 on the bases, -0.8 on double plays, -0.7 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.

Not in the 2013 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.

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.
