BEIJING, Sept 26: Top seed David Ferrer was dumped out of the China Open on Thursday, while on the women’s side home favourite Zheng Jie cruised through to the quarter-finals.

Elsewhere on day four of the tournament, defending women’s champion Agnes Szavay lost in straight sets, but second seed Ana Ivanovic and 2007 men’s champion Fernando Gonzalez advanced.

Ferrer, playing his first match here, lost to world number 92 Dudi Sela of Israel, 6-3, 6-3, in just 70 minutes.Sela took advantage of a string of unforced errors by the world number five, part of a strong Spanish contingent here, winning comfortably.

“He played better than me and he fought more than me. I didn’t fight a lot because psychologically I am not in a good moment now,” Ferrer said.

“Maybe I was a little bit tired because I didn’t sleep very well for two nights,” added Ferrer, who helped Spain reach the Davis Cup final at the weekend with a win over Andy Roddick, the second seed here.

Roddick qualified for the last eight with a 6-4, 6-3 win over compatriot Brendan Evans, ranked 187 in the world.

Meanwhile, Zheng followed up her first-round victory over 10th-ranked Agnieszka Radwanska with a 6-1, 6-2 win over Japanese veteran Ai Sugiyama. Zheng, who will play Ivanovic in the quarter-finals, beat the Serbian on the way to the Wimbledon semi-finals this year, but she said it would be tough to repeat the feat.

“Ana is a really good player. I won at Wimbledon and that brought me more confidence but there is a difference between a grass court and a hard court,” she said. “I just want to try my best and let the crowd see an exciting match,” added Zheng, the only Chinese player left in the men’s or women’s draws.

The best-ever performance by a Chinese player at this tournament was by Peng Shuai, who reached the semi-final of the 2006 China Open but was one of the first-round losers on Tuesday, along with the host nation’s top player Li Na.

Ivanovic, who beat France’s Alize Cornet 6-1, 7-6 (7-1), said she was confident she could reclaim the number one ranking, currently held by Serena Williams.

Chile’s Gonzalez, the men’s number three seed, struggled in the first set against Japan’s Go Soeda but eventually won through to the quarter-finals 3-6, 7-6 (7-4), 6-1.

In other matches played on Thursday, Spain’s former world number one Juan Carlos Ferrero beat compatriot and number five seed Fernando Verdasco 7-5, 6-4.

Slovakia’s Dominika Cibulkova beat eighth seed Anna Chakvetadze, while Germany’s Bjorn Phau put out men’s eighth seed Sam Querrey and Hungary’s Szavay lost to Anabel Medina Garrigues of Spain.

Svetlana Kuznetsova, Vera Zvonareva, Tommy Robredo, Rainer Schuettler and Richard Gasquet also advanced.
