The Sensory Anchor: Front Leg Proprioception and Pitching Effectiveness Proprioception is the sensory system that allows a pitcher to achieve and maintain a "solid foot strike," much like ensuring an anchor is firmly set. This sensory awareness of the front leg's position and stability is fundamental for balance, efficient power transfer, and pitch accuracy. Without reliable proprioceptive feedback, the foot strike is likely to be inconsistent, leading to loss of control and proper positioning.
