BEIJING (AFP) - Top seed Tomas Berdych of the Czech Republic overcame his countryman and eighth seed Jiri Vesely 7-6(1), 3-6, 6-2 at the Shenzhen Open on Friday (Sept 30), bouncing back from a second-set loss to secure a spot in the semi-finals.

The 31-year-old Berdych, ranked 9th in the world, will face Thomaz Bellucci on Saturday after the Brazilian bulldozed over fourth seed Bernard Tomic 6-2, 6-2, winning 93 per cent of first serve points and slamming 14 aces to Tomic's three.

Winning the hour-long quarter-final contest gave the Brazilian a 2-1 edge in their head-to-head record in ATP competition, with Tomic winning their last clash three years ago in the US.

Third seed Richard Gasquet of France meanwhile squeezed past German qualifier Mischa Zverev 7-6(4), 7-6(2) to win a place in the semi-finals against Janko Tipsarevic of Serbia.

While knocking down only three aces to Zverev's 10, he won 77 percent of his first serve points in the two-hour clash.

On Saturday, he will face Tipsarevic, against whom he has a 2-0 head-to-head record in ATP competition.

The 32-year-old Serbian, once the world's number eight player, seriously injured his foot two years ago and is now ranked 224th on the ATP list.
