The Situation: Your ball is hung up on the downside of a hill in the rough.
Why It’s Difficult: The slope moves the bottom of your swing arc back, making it easy to catch the ball fat or thin, and the rough exacerbates any errors.
The solution: Set your body level with the lie by tilting your torso to the left until your left shoulder sits lower than your right. Get that correct and all you need to do is swing down hill. Don’t hang back to fight the pull of gravity as this moves the bottom of your swing arc even farther back and makes whiffing the ball a real possibility.
