Alec Mills is a pitcher for the Chicago Cubs. In 2021 he hit 0 home runs and knocked in 0 RBIs, notching 1 hit across 36 plate appearances in 21 games. His batting average was .031, 87.2% lower than the league average of .244. He reached base at a .031 clip and slugged .063, for an OPS of .094, 87.1% lower than the league mark of .728. He averaged 67.2 mph off the bat, hit 10.0% of balls in play at 95 mph or better and made contact on 61.4% of his swings. Adjusted for his ballpark and league, his -91 wRC+ puts his offence 191% below average. That comes to -0.7 dbWAR — -8.4 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.

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.
