2026 Tunneling

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

At Decision

23 ft out · ~280ms before arrival

At the Plate

Where they actually cross

CHCUSIFCFFST

Decision point computed from Statcast kinematics (vx0/vy0/vz0, ax/ay/az) by projecting each pitch back to y = 23 ft. Coordinates in catcher’s view: 1B on the left, 3B on the right. RHP.

2026 Divergence from a Shared Origin

Every pitch type launched from the same decision-point — how far apart they end up by the plate. Bigger fan = harder arsenal to square up.

Distances from origin (in inches) show how far each pitch type separates itself from the common launch point by plate arrival. RHP.
