Jon Jay is a left fielder for the Los Angeles Angels. In 2021 he hit 0 home runs and knocked in 1 RBI, notching 5 hits across 14 plate appearances in 4 games. His batting average was .357, 46.5% higher than the league average of .244. He reached base at a .357 clip and slugged .357, for an OPS of .714, 1.9% lower than the league mark of .728. He averaged 83.2 mph off the bat, hit 8.3% of balls in play at 95 mph or better and made contact on 85.7% of his swings. Adjusted for his ballpark and league, his 96 wRC+ puts his offence 4% below average. That comes to 0.0 dbWAR — -0.0 runs with the bat, -0.0 on the bases, -0.2 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.
