Casting is one of the most common causes of loss of power and excessive spin on the golf ball. It is defined as an early release of the golf club during the downswing. This can result in a weak impact position with the left wrist being cupped at impact. It adds loft to the face of the club and as a result we see a loss of power and consistency. At impact we should see the shaft leaning slightly toward the target, this helps to deloft the club and creates a more powerful impact position.
Physical Parameters Affecting the Casting and How to Diagnose:
There are many physical limitations that can cause a player to cast the golf club. Lack of or limited contribution of the lower body in the downswing is one of the leading causes. This will cause the upper body to over work and thus throw the golf club from the top. Poor lower body movement in the golf swing can be due to limited hip mobility, ankle restrictions, inability to separate the lower body from the upper body and weakness in the main core musculature (glutes and abs). In addition, any limitations in the wrists or wrist injury can also prevent the club from setting and releasing properly. Without extension in the trail wrist, it is difficult to maintain a good set during the downswing.
