Justin Dunn is a pitcher for the Seattle Mariners. In 2021 he hit 0 home runs and knocked in 1 RBI, notching 1 hit across 3 plate appearances in 2 games. His batting average was .333, 36.7% higher than the league average of .244. He reached base at a .333 clip and slugged .667, for an OPS of 1.000, 37.4% higher than the league mark of .728. He averaged 95.1 mph off the bat, hit 100.0% of balls in play at 95 mph or better and made contact on 50.0% of his swings. Adjusted for his ballpark and league, his 177 wRC+ puts his offence 77% above average. That comes to 0.0 dbWAR — +0.3 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.
