Australian Open: Hingis battles back for win

Martina Hingis survived an early scare to reach the fourth round of the Australian Open.

The top seed came back from 4-2 down to beat wild card entry Virginie Razzano of France 7-5, 6-1.

The Swiss ace rallied to take the opening set in 39 minutes - about the length of her first two matches.

She then pulled away, with half her points coming on errors by the 17-year-old Razzano.

Hingis now meets Italy's Rita Grande, who beat Australian Evie Dominikovic 6-3, 6-4.
