Batter Lab

Pitch-level Statcast for one hitter. Pick a batter and the data shows how he handles each pitch type, velo band, and pitcher hand: whiff rate, xwOBA, hard-hit rate, and average exit velocity, with the sample size on every line. You set the filters, the data answers. Statcast covers 2023 to 2025.

Every number is a real Statcast count with its sample size (n) shown, never a guaranteed pick or a fabricated probability. Whiff % is swinging strikes over swings · xwOBA is the expected wOBA on contact · hard-hit is exit velocity 95+ mph. You set the filters, the data answers, you decide. Back to research →
