Harold Castro is a second baseman for the Colorado Rockies. In 2023 he hit 1 home run and knocked in 31 RBIs, notching 65 hits across 270 plate appearances in 91 games. His batting average was .252, 1.4% higher than the league average of .248. He reached base at a .275 clip and slugged .314, for an OPS of .589, 19.8% lower than the league mark of .734 — 14th of 16 on his team, and 407th of 461 among MLB batters with 100+ plate appearances. He averaged 85.7 mph off the bat, hit 28.7% of balls in play at 95 mph or better, barrelled 3.1% of them and made contact on 71.4% of his swings. Adjusted for his ballpark and league, his 53 wRC+ puts his offence 47% below average. That comes to -0.5 dbWAR — -13.7 runs with the bat, -0.3 on the bases, +0.2 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.
