Djokovic broke again, but rather than race through the set he surrendered a 5-2 lead. Tipsarevic saved a set point at 5-4 when finding the baseline with a forehand and drew level at 5-5. Tipsarevic continued his brutal assault and secured a break for 6-5, only to produce his worst game of the set to allow Djokovic to force a tiebreak, which the world No. 1 thoroughly dominated.

The second set followed the same path as the first, with Tipsaervic forcing Djokovic behind the baseline with some wonderful hitting that drew gasps from the crowd.

The second-set breaker was far more even and it was Djokovic who blinked first when pulling a forehand into the tramline. Tipsarevic did not pass up the opportunity and levelled the match when Djokovic threw a forehand over the baseline.

Djokovic raced through the third set to love and then sapped the final bit of spirit out of his opponent with an amazing get of a drop volley in the first game of the fourth set.

Djokovic called for the trainer to attend to a blister, but it was Tipsaervic who was the beaten man physically as he had run himself to a standstill and offered his hand when 3-0 down in the fourth set.

Nadal resumed the match 3-0 down in the opening set from Wednesday, but after clinching it on a tiebreaker, the Spaniard made light work of the next two, dismissing Luxembourg's Giles Muller 7-6, 6-1, 6-2.

"It was a tough day yesterday for the players and the fans who waited many hours. Sorry about that, but thanks for still being here," Nadal said.
