Danny Duffy is a pitcher for the Kansas City Royals. In 2019 he hit 0 home runs and knocked in 0 RBIs, notching 1 hit across 4 plate appearances in 2 games. His batting average was .250, 0.9% lower than the league average of .252. He reached base at a .250 clip and slugged .250, for an OPS of .500, 34.0% lower than the league mark of .758. He averaged 77.0 mph off the bat, hit 50.0% of balls in play at 95 mph or better and made contact on 75.0% of his swings. Adjusted for his ballpark and league, his 28 wRC+ puts his offence 72% below average. That comes to -0.0 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.
