Keith Hessler is a pitcher for the Arizona Diamondbacks. In 2015 he hit 0 home runs and knocked in 0 RBIs, notching 1 hit across 1 plate appearances in 1 game. His batting average was 1.000, 293.0% higher than the league average of .254. He reached base at a 1.000 clip and slugged 1.000, for an OPS of 2.000, 177.3% higher than the league mark of .721. He averaged 72.4 mph off the bat and made contact on 100.0% of his swings. Adjusted for his ballpark and league, his 488 wRC+ puts his offence 388% above average. That comes to 0.1 dbWAR — +0.4 runs with the bat, -0.0 on the bases, +0.0 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.

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.
