*Del Potro 6-4 0-6 1-4 Nadal
Juan Martin del Potro spanks the forehand into Rafael Nadal's backhand.
The Spaniard can only slice into the top of the net for 30-30.
But that mini-chance is snuffed out before it has a chance to develop into anything more serious.
Rafael Nadal is darting around the court, looking up for the fight.
Juan Martin del Potro looks like he wants a cab home.
