Showing no signs of nerves, world number 126 Troicki forced a set point at 6-5 in the first set and led 4-2 in the second before Nadal finally wore him down to clinch victory in two hours, 35 minutes.

"He played very, very aggressively," Nadal said in a courtside interview.

"Today I was struggling at some times in the match. I couldn't get the rhythm in the beginning but in the third set I think I played a bit better."

In the cool evening conditions, Nadal missed the chance to serve out for the first set at 5-4 and then had to save a set point in the 12th game, before winning the tiebreak 7-3.

Troicki then broke in the third game of the second set on his way to a 4-2 lead but Nadal levelled at 4-4 and after pinching the set, he eased through the third to win a match that finished in the early hours of Tuesday.
