Viktor Troicki has pulled off something of a shock by beating Juan Monaco to set up a fourth-round clash with fellow Serbian Novak Djokovic.

Troicki, ranked 34th, beat 15th-placed Monaco in a hard-fought, straight-sets victory.

Monaco looked to be in charge of the first set, breaking Troicki early on and moving into a 5-3 lead. However, the Argentinian lost his final two service games of the set, allowing Troicki to come back and nick it 7-5.

Monaco then lost his first service game of the second, before levelling it up later on in the set.

However, once again he was broken in his final service game, again handing the set to Troicki 7-5.

The third set saw Troicki drop his serve first, coming in the fifth game, but once again it was Monaco who faded towards the end, losing his last two service games to give Troicki a 7-5 7-5 6-3 victory.
