SHANGHAI, Oct. 14 (Xinhua) -- World number five Tomas Berdych of the Czech Republic survived a stern test against Jack Sock, edging past the American 7-6 (3), 4-6, 6-4 for the third round at the ongoing Shanghai Rolex Masters on Wednesday.
Sock was made to rue converting just three of 14 break point chances, including missing three break points in the final game as Berdych served out the victory.
The Czech recently won his first ATP World Tour title of the season in Shenzhen, and now he will take on 10th seed Gilles Simon, who rallied from a set down to beat Leonardo Mayer 6-7 (0), 6-4, 6-2 in two hours and 37 minutes.
The Frenchman has enjoyed success against Berdych in the past, winning seven of their 11 meetings, including a clash in the Shanghai quarterfinals last year.
