Wozniacki moves into 3rd round at Australian Open

Top-seeded Caroline Wozniacki stayed on track to keep her No. 1 ranking in women's tennis with a 6-1, 7-6 (4) win over Anna Tatishvili of Georgia in the second round of the Australian Open on Wednesday.

Wozniacki rallied from 4-1 down in the second set and needed a medical timeout at 4-5 to get treatment for a blister on her left big toe. The Danish player saved one set point in the 10th game and forced a tiebreaker, which she won when Tatishvili sprayed a forehand wide.

Wozniacki needs to reach the quarterfinals to have a chance of staying at No. 1, a ranking she held for all but one week in 2011.
