I am having a problem with my stance when on the fairway.

It happens more in the last 4 holes after completing 14 or so that makes me think that it has something to do with fatigue.

The problem is that I hit the ground with the club before I make contact with the ball, I seem to bend my knees whilst swinging the club downwards toward the ball which then makes the club hit the ground before hitting the ball.

How can I ensure that I don’t bend my legs more when I am in the middle of the down swing but stay in the position that I was in when making the back swing.

Thanks guys


John
