Jeff Ritter: Fix Your Slice
You want to fix your slice, so Jeff Ritter believes it is important to get the club face into a reasonable position. He suggests taking a set up and swinging a quarter of the way into the back swing, focusing on the back palm. The palm should be looking down, as if one could bounce a basketball up and down at waist height. This will ensure the club face is facing the ground towards the golf ball.
Get club face in the right position to fix your slice
Ritter suggests imagining the club face is a mirror and trying to reflect sunlight off it, as if sending an S.O.S. to be rescued. This will help to ensure the club face is in the right position. He also emphasizes the importance of hand activity to control the club face and ultimately control the ball play.
