Australian Open: Luckless Li says she blacked out during final

MELBOURNE (AFP) - China's Li Na was left cursing her luck after she twice took a tumble and briefly knocked herself unconscious in a disastrous Australian Open final on Saturday.

Li was a set up against Victoria Azarenka when she first went over on her left ankle, and she fell again in the third set, immediately after a break for Australia Day fireworks, smashing the back of her head on the court.

The world No. 6 did not blame her misfortune for the 6-4, 4-6, 3-6 defeat, but she admitted she was a "little bit worried" when she blacked out after banging her head.

"I think I was a little bit worried when I fell down and my head hit the floor, because for two seconds I couldn't really see anything. It was totally black," she said.
