Aaron Altherr is a left fielder for the New York Mets. In 2019 he hit 1 home run and knocked in 3 RBIs, notching 5 hits across 66 plate appearances in 41 games. His batting average was .082, 67.5% lower than the league average of .252. He reached base at a .136 clip and slugged .164, for an OPS of .300, 60.4% lower than the league mark of .758. He averaged 85.5 mph off the bat, hit 22.9% of balls in play at 95 mph or better, barrelled 5.7% of them and made contact on 65.0% of his swings. Adjusted for his ballpark and league, his -27 wRC+ puts his offence 127% below average. That comes to -0.9 dbWAR — -10.5 runs with the bat, -0.0 on the bases, -0.9 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.

Contact rate65.0%

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.
