Top seeds Alexandra Dulgheru, Anabel Medina Garrigues, and Agnes Szavay all advanced to the quarterfinals at the GDF Suez Grand Prix in Budapest on Thursday.

Seeds Timea Bascinszky of Switzerland and Roberta Vinci of Italy fail to make it through at the fourth day of the women's outdoor clay court.

Alexandra Dulgheru's match with Russia's Anna Chakvetadze was tied one set apiece overnight as bad light had stopped play on Wednesday.

The second-seeded Romanian won the round in 7-6, 1-6, 6-2 and advanced to the quarterfinals. Dulgheru, the highest remaining seed in the tournament after Patty Schnyder knocked out top seed Alisa Kleybanova, will meet Anastasija Sevastova of Latvia in the last eight.

Third seed Bacsinszky from Switzerland lost 6-0, 6-4 to the 2008 champion Alize Cornet from France, while the sixth-seeded Italian Roberta Vinci fell 6-4, 6-0 to Zuzana Ondraskova of the Czech Republic.

The reigning champion and seventh seed Agnes Szavay beat the Austrian Yvonne Meusberger 7-5, 6-3. In a tight first set, both players broke the others serve three times in a row, before the Hungarian, after fifty minutes, closed out the first set.

Szavay broke the Austrian's serve twice in the second set to advance to the quarterfinals. Hungary's other hope, Arn Greta had chances to win the first set but eventually lost 7-5, 6-3 to fourth seed Anabel Medina Garrigues of Spain, who will play Ondraskova in the next round.
