What physical limitation is commonly associated with the swing fault known as "casting"?

Casting is a swing fault that occurs when a golfer prematurely releases the wrist hinge during the downswing, leading to a loss of power and precision in the shot. This particular fault is often linked to insufficient wrist mobility. When the wrists lack the necessary flexibility, the golfer may have difficulty maintaining the proper angle and timing needed to execute an effective swing. As a result, this limitation can lead to an early casting action, causing the clubhead to move away from the optimal path during the swing.

In the context of swing mechanics, the wrists play a critical role in creating and maintaining lag, which is essential for generating clubhead speed and ensuring control over ball striking. When wrist mobility is restricted, it can significantly alter the dynamics of the swing, making it difficult for the golfer to achieve the desired mechanics that contribute to effective and powerful ball striking.
