Wuhan (China), Sep 25 (IANS): Denmarks world number two Caroline Wozniacki defeated Swedens Rebecca Peterson on Tuesday to advance to the third round of the Wuhan Open.

The reigning Australian Open champion beat the qualifier 6-4, 6-1 in one hour and 28 minutes in her opening game of the tournament, having received a bye for the first round, reports Efe.

Wozniacki has struggled with injuries since her winning the title at Eastbourne in June, suffering first round exits at Montreal, Cincinnati and Tokyo.

Against Peterson, the Dane was always in control, making just four unforced errors and first-serving well over 70 percent throughout the match.

After an early break gave Wozniacki a 3-1 lead, she broke the Swede again to set her up to serve for the set at 5-2.

Peterson rallied, however, breaking the world number 2 after saving three set points, before succumbing 6-4 in the first set.

That attempt at a comeback appeared to drain Peterson of much of her energy, and the second set was a stroll for Wozniacki, who closed out the match 6-1.

She will face Puerto Rico's Monica Puig in the round-of-16 on Wednesday.
