Aaron Wilkerson is a pitcher for the Milwaukee Brewers. In 2019 he hit 1 home run and knocked in 2 RBIs, notching 1 hit across 3 plate appearances in 2 games. His batting average was .333, 32.1% higher than the league average of .252. He reached base at a .333 clip and slugged 1.333, for an OPS of 1.667, 120.0% higher than the league mark of .758. He averaged 88.0 mph off the bat, hit 50.0% of balls in play at 95 mph or better and made contact on 100.0% of his swings. Adjusted for his ballpark and league, his 325 wRC+ puts his offence 225% above average. That comes to 0.1 dbWAR — +0.8 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.

A barrel is a batted ball whose exit velocity and launch angle have historically produced at least a .500 average and 1.500 slugging — 98 mph within 26–30°, widening to 8–50° by 116 mph. Reconstructed from Statcast's published anchor points, which reproduces them exactly; the interior is within a degree. Sweet spot (8–32°) is an exact definition.

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.
