Jack Mayfield is a second baseman for the Los Angeles Angels. In 2022 he hit 1 home run and knocked in 6 RBIs, notching 13 hits across 74 plate appearances in 23 games. His batting average was .186, 23.5% lower than the league average of .243. He reached base at a .230 clip and slugged .271, for an OPS of .501, 29.1% lower than the league mark of .706. He averaged 84.5 mph off the bat, hit 24.5% of balls in play at 95 mph or better, barrelled 1.9% of them and made contact on 74.8% of his swings. Adjusted for his ballpark and league, his 38 wRC+ puts his offence 62% below average. That comes to -0.3 dbWAR — -5.2 runs with the bat, +0.1 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.
