In the Paes-Stepanek match, after trading breaks, the opening set was on serve till the 11th game. The Indo-Czech pair had its first set point in the next game but Stepanek hit a forehand to net.
However, the Czech hit a volley winner to earn third set point, which they converted to shoot ahead.
It wasn't a good start to the second set for Paes and Stepanek as they were down by two break points in the first game. Stepanek though served well to save both, the second one with an ace.
The fourth seeds had their first break chance in the next game but Paes could not return a Llodra serve.
It was on serve till Paes dropped his serve in the seventh game. It all turned around when Mahut earned that break chance with a well-calculated lob winner.
The French pair never looked back after that and Llodra served out the set in the 10th game to make it an even affair.
The keenly fought third set turned in Paes-Stepanek favour when the Czech hit a winner to earn a break chance and Mahut helped the rivals when he hit a forehand return to net.
