MELBOURNE, Jan. 15 (Xinhua) -- Fourth seed Li Na won 7-5 in the tiebreak of the second set to beat Swiss qualifier Belinda Bencic in straight sets and advanced into the third round here on Wednesday at the Australian Open.
The two-time runner-up dominated the first set, playing only 22 minutes to win 6-0 without dropping a game and conceding only 10 points.
Bencic put up more of a challenge in the second set and broke Li twice to force a tiebreak. But Li prevailed to win 7-5.
"She played exactly like Martina Hingis, and it's very tough to play a decent player I have never seen before," said Li. "I think today she gave me very tough time in the second set. But I was really happy in the end I can use my experience to win the match."
The 2011 French Open champion defeated 16-year-old Ana Konjuh, the youngest player in the tournament, by dropping just two games in the first round. After Wednesday's victory over Bencic, the Chinese completed back-to-back wins over the two youngest players in the draw. Konjuh and Bencic split the four junior majors in 2013.
"Both players are pretty good. If they play more tournaments on the tour, for sure they would be very good," she said.
Li will play against the 26th seed Lucie Sfarova on Friday's third round for a place in the top 16, who beat qualifier compatriot Lucie Hradecka in three sets.
