In playing a shot just over 30 yards with your sand wedge, I would ask you to give a lot of consideration to your posture and how you prepare to play this shot. It's important that you stay in your striking position through the strike and watch the ball roll to a stop.

If you work really hard on your posture, you'll get a much more consistent swing arc at the bottom of your swing, as well as better contact with the ball. Bend at the hips and measure out your distance to the ball. Let the club hang slightly off the ground.

Make your swing and strike the ball. Maintaining your spine angle throughout the entire shot allows your arms to swing freely and completely.

Watch the ball from your striking position so you can pick up all the information you can for the putt. You'll also be much more consistent in striking the ball if you're not coming out of the strike. So, please hold your striking position after every shot, it is critical for achieving short game success.
