BEIJING, Sept 13: Third seed Marcos Baghdatis survived a second tough test in less than 24 hours to progress to the quarter-finals of the China Open on Wednesday with a 7-6, 6-4 victory over Taiwan's Wang Yeu-Tzuoo.

The Cypriot needed a third-set tiebreak to overcome German Denis Gremelmayr late on Tuesday and was equally tested by Wang, who was cheered on by a crowd delighted to see a Chinese man competing with one of the world's top players.

Wang never gave an inch without a fight and exploited the world No 9’s lapses of concentration to force a tiebreak in the first set and break Baghdatis early in the second.

Baghdatis, however, drew on the competitive spirit he so amply displayed in a five-set defeat to Andre Agassi at the US Open two weeks ago to break back and then break the stubborn Wang's service again.

He finally secured the victory with a crosscourt winner and will next face Thai Danai Udomchoke, who progressed when Croatia's seventh seed Ivo Karlovic retired while 6-2, 3-1 down.

Slovakia's Dominik Hrbaty was the first seed to reach the quarter-finals when he overcame a second-set implosion to beat Austrian Alexander Peya 6-1, 2-6 6-0.

Nikolay Davydenko played through jet lag to claim the last place in the second round with a 6-3, 6-4 win over Dane Kenneth Carlsen in a match held over from Tuesday to allow the Russian more time to rest.
