New York: World No.39 tennis player Peng Shuai beat 28th seeded Italian Roberta Vinci 6-4, 6-3 to reach the US Open last 16, equalling her personal best in the tournament.
Vinci became the second seeded player to be defeated by Peng after the fourth seeded Agnieszka Radwanska, reports Xinhua.
"I am really happy. I really wanted to win because I know I have a chance," said Peng, who will next face the winner between Lucie Safarova and Alize Cornet, both seeded players.
"Both Cornet and Safarova are really good players. Safarova is lefty. Sometimes it's different. I know this year she has been doing really good. I will try my best," said Peng about the fourth round.
Peng, the only Chinese player left in women's singles, saved three break points to win the first set 6-4. Vinci did a better job in slicing the ball in the second set but Peng managed to break again to close the match 6-3.
