"Tired" Nadal admits to have run out of his batteries

London, Nov 28(ANI): Spanish tennis player Rafael Nadal has admitted that he is completely worn out after his recent injuries.

Adding to the 23-year-old's misery, the most dominant player in the world last year crashed 7-6 6-3 to Novak Djokovic, which ended his World Tour Finals campaign with a third successive defeat.

"Sometimes your battery finishes and you have to go out and buy another one. At the moment, I just feel very tired," The Sun quoted Nadal, as saying.

The defeat followed similar straight sets disappointments against Swede Robin Soderling and Russian Nikolay Davydenko.

Nadal has now lost four games in a row on the Tour- his worst run since he was 17. (ANI)
