Corey Kluber is a pitcher for the New York Yankees. In 2021 he hit 0 home runs and knocked in 0 RBIs, notching 0 hits across 2 plate appearances in 1 game. His batting average was .000, 100.0% lower than the league average of .244. He reached base at a .000 clip and slugged .000, for an OPS of .000, 100.0% lower than the league mark of .728.

That comes to -0.0 dbWAR — -0.5 runs with the bat, +0.0 on the bases, +0.0 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.
