Aaron Hill is a third baseman for the San Francisco Giants. In 2017 he hit 1 home run and knocked in 7 RBIs, notching 9 hits across 80 plate appearances in 34 games. His batting average was .132, 48.1% lower than the league average of .255. He reached base at a .250 clip and slugged .235, for an OPS of .485, 35.3% lower than the league mark of .750. He averaged 87.7 mph off the bat, hit 33.3% of balls in play at 95 mph or better, barrelled 2.6% of them and made contact on 83.6% of his swings. Adjusted for his ballpark and league, his 36 wRC+ puts his offence 64% below average. That comes to -0.4 dbWAR — -6.4 runs with the bat, -0.0 on the bases, -0.4 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 rate83.6%

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.

Runners on includes runners in scoring position, which is the convention every reference uses. Rows under 25 plate appearances are marked thin — at that size a rate moves several dozen points on one hit. Counted from play-by-play, 2017.

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.
