Sydney: An emotional Novak Djokovic overpowered long-time rival Rafael Nadal and led Serbia to victory in the inaugural ATP Cup on Sunday, capping a perfect build up to his Australian Open title defence. The World No. 2 blasted the top-ranked Spaniard off court 6-2, 7-6 after World No. 10 Roberto Bautista Agut caned Serbia's Dusan Lajovic 7-5, 6-1 in the other singles.

Nadal low on energy

A fresh Djokovic returned to Sydney's Ken Rosewall Arena for the deciding doubles, but Nadal opted not to, saying his energy levels were too low, with Feliciano Lopez partnering Pablo Carreno Busta. But they proved no match for Djokovic and Viktor Troicki, who bounced back from a break down in the first set to romp home 6-3, 6-4 and ensure Serbia was the last country standing from the 24 that began the season-opening event.
