Daniel Mengden is a pitcher for the Oakland Athletics. In 2019 he hit 0 home runs and knocked in 0 RBIs, notching 0 hits across 2 plate appearances in 1 game. His batting average was .000, 100.0% lower than the league average of .252. He reached base at a .000 clip and slugged .000, for an OPS of .000, 100.0% lower than the league mark of .758. Adjusted for his ballpark and league, his -123 wRC+ puts his offence 223% below average. That comes to -0.0 dbWAR — -0.6 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.

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.
