Joaquin Arias was a shortstop for the San Francisco Giants. In 2015 he hit 1 home run and knocked in 4 RBIs, notching 12 hits across 59 plate appearances in 39 games. His batting average was .207, 18.7% lower than the league average of .254. He reached base at a .207 clip and slugged .276, for an OPS of .483, 33.1% lower than the league mark of .721. He averaged 78.8 mph off the bat, hit 16.7% of balls in play at 95 mph or better and made contact on 77.9% of his swings. Adjusted for his ballpark and league, his 26 wRC+ puts his offence 74% below average. That comes to -0.3 dbWAR — -5.0 runs with the bat, +0.1 for the ballpark, +0.2 on the bases, +0.4 on double plays, -0.1 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.
