As a rule, when pitching, you will have a narrower stance, be in a more crouched position, have a opened club face and will hit the ball with a more descending blow.
Be careful to avoid the most common fault when pitching, "scooping" the ball. To get the ball airborne on a short shot you have to hit down on it with a descending blow, hitting the ball first and trusting the club's loft the same way you would with a full-force shot.
