Belarusian Victoria Azarenka, the No 20 seed, beat Frenchwoman Clara Burel6-1, 6-4 to reach the third round of the US Open in New York on Wednesday.

The three-time runner up’s victory was looking unlikely at one stage in the match, with Azarenka taking a medical timeout down 3-1 in the second set. She was in tears, with what appeared to be a migraine severely hampering her.

However, the former No 1 bounced back strong, and was emotional after closing out the match in straight sets to make the third round in New York.

Azarenka, ranked No 20, will play Chinese Yafan Wang next.

The 35-year-old Belarusian won against Ukrainian qualifier Yulia Starodubtseva (3-6, 6-1, 6-1) in the previous round.

In the previous round, Burel, ranked No 56, edged out American Sloane Stephens (0-6, 7-5, 7-5).
