José Rondon is a position player for the St. Louis Cardinals. In 2021 he hit 3 home runs and knocked in 9 RBIs, notching 21 hits across 90 plate appearances in 62 games. His batting average was .263, 7.7% higher than the league average of .244. He reached base at a .322 clip and slugged .412, for an OPS of .735, 0.9% higher than the league mark of .728. He averaged 84.4 mph off the bat, hit 33.8% of balls in play at 95 mph or better, barrelled 4.6% of them and made contact on 75.7% of his swings. Adjusted for his ballpark and league, his 106 wRC+ puts his offence 6% above average. That comes to 0.2 dbWAR — +0.1 runs with the bat, +0.3 on the bases, -1.6 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.
