Federer lays Davydenko hoodoo to rest

ROGER FEDERER and Serena Williams needed all their fighting qualities to stay in the Australian Open on Wednesday after Li Na stunned Venus Williams to become the second Chinese to reach a grand slam semi-final.

Federer reeled off 13 games in a row to dig himself out of trouble and beat Russia’s Nikolay Davydenko 2-6 6-3 6-0 7-5 in a wildly fluctuating match.

Serena was also staring down the barrel in her quarter-final against Victoria Azarenka of Belarus before she recovered to win 4-6 7-6 6-2.
