Muzza's match crucial is at 3:30pm this afternoon.

Djokovic had never lost to Cilic before and when he saved two match points in the 11th game of the second set, you would have bet on him to emerge the victor.

But the big Croat, who had seen match points come and go against Roger Federer at Wimbledon, played a great tiebreak and closed out the match 6-4 7-6.
