Alexi Amarista is a shortstop for the Colorado Rockies. In 2017 he hit 3 home runs and knocked in 19 RBIs, notching 40 hits across 176 plate appearances in 91 games. His batting average was .238, 6.6% lower than the league average of .255. He reached base at a .269 clip and slugged .351, for an OPS of .620, 17.4% lower than the league mark of .750 — the second worst on his team, and 389th of 435 among MLB batters with 100+ plate appearances. He averaged 83.9 mph off the bat, hit 18.8% of balls in play at 95 mph or better, barrelled 0.9% of them and made contact on 80.7% of his swings. Adjusted for his ballpark and league, his 57 wRC+ puts his offence 43% below average. That comes to -0.3 dbWAR — -8.0 runs with the bat, +0.1 on the bases, -0.6 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.
