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
FFSLCHCUSIFCFS
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. LHP.
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. LHP.
