Caroline Wozniacki powered her way past Greta Arn, of Hungary, to reach the third round of the Pan Pacific Open women’s tennis tournament yesterday.

The Danish top seed put the disappointment of withdrawing through illness in the first round last year behind her with a 6-1, 6-3 victory.

US Open finalist Vera Zvonareva and French Open champion Francesca Schiavone safely went through, but last year’s French Open champion 10th seed Svetlana Kuznetsova fell to Andrea Petkovic 6-3, 7-5.

Zvonareva, who reached a career-high fourth after the US Open, struggled to hold her serve before serving out for a 6-3, 6-3 win over Sara Errani while Schiavone beat Alexandra Dulgheru 7-5, 6-3.

Top seed Wozniacki comfortably took the first set as Arn hit seven double faults, one on a break point, and failed to keep her service games three times.

Arn, who defeated Wozniacki when the Dane was ranked 120th in 2007, stopped double-faulting in the second set, but Wozniacki stood firm in her service games and never gave the Hungarian a single break opportunity in the set.

“It’s a new tournament every year for me. I always try to do my best and I’m happy that I won and got through this first match,” said Wozniacki who won the Japan Open two years ago.
