Today's tip comes from the late (and great) Seve Ballesteros.
There are two types of shots from off the green: The Pitch (goes high and lands soft) and The Punch (that runs).
For the basic pitch, play the ball
forward in your stance. Your club face is set slightly open to the target. Use a regular grip, but your hand is pointed just inside your left leg.
Weight is 60% on the left side with an open stance.
Feet, knees, hips and shoulders are all in alignment.
The swing path is out to in and it is also fairly steep to get the right height of the ball.
Notice that in the backswing, the angle between the left
arm and the clubhead form a right angle.
Make sure the clubhead is not closed at the top. The right knee moves in towards the target.
