2026 Swing-Out Snapshot

Commit at the decision point, then fast-forward 150ms. Where is each pitch when your bat crosses the zone? Two views of the same moment — catcher-facing and from the side.

Each pitch is launched from a shared decision point (4.53′ height) and advanced using its own Statcast kinematics (release velocity + constant acceleration, so gravity, drag, and Magnus are all in the curve). LHP.

2026 Tunneling

Where pitches are when the hitter commits — and where they end up. Tighter cluster on the left = more deceptive arsenal.
