Billy Cook is a center fielder for the Pittsburgh Pirates. In 2026 he hit 0 home runs and knocked in 2 RBIs, notching 9 hits across 45 plate appearances in 33 games. His batting average was .200, 17.9% lower than the league average of .244. He reached base at a .200 clip and slugged .267, for an OPS of .467, 35.1% lower than the league mark of .719. He averaged 80.5 mph off the bat, hit 22.2% of balls in play at 95 mph or better and made contact on 63.4% of his swings. Adjusted for his ballpark and league, his 19 wRC+ puts his offence 81% below average. That comes to -0.2 dbWAR — -4.3 runs with the bat, +0.5 on the bases, -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.
