Top seed Caroline Wozniacki zipped past Chang Kai-Chen of Chinese Taipei 6-0, 6-0 in just 47 minutes on Thursday to reach the third round of U.S. Open.
The 20-year-old Dane dispatched Chang with a strong attacking game against the world number 84.
Chang implemented the same strategy against Wozniacki, coming in to the net and going for her shots. Unfortunately for her, those shots just weren't finding the court, as they either sailed long or landed in the net.
The 19-year-old Chang, who defeated then No. 1 seed Dinara Safina in Tokyo in 2009 and reached the quarterfinals in Kuala Lumpur this year, committed a staggering 26 unforced errors, with only six winners during the match.
Wozniacki posted a cleaner game with 12 unforced errors and seven winners.
"I've played tough matches in the previous weeks. I've been playing really great tennis. I'm feeling good and no worries," said Wozniacki.
The closest Chang came to break Wozniacki the entire match came in the final game of the second set, when she pushed her to two deuce points. But a clean backhand down-the-line winner from Wozniacki ended the match, denying Chang her first third-round appearance at Flushing Meadows.
Wozniacki, the U.S. Open Series champion and New Haven titlist, will face yet another Chinese Taipei challenger in the third round when she meets Chan Yung-Jan, a straight-set winner over Tamira Paszek.
Talking about her next opponent, Wozniacki said: "We played a lot in the juniors. She's a year older than me, but we know each other from back then. So, I'm familiar with her."
