BERLIN: Defending champion Nadia Petrova of Russia beat compatriot Elena Dementieva 6-3, 6-3 yesterday to advance to the quarter-finals of the German Open.
The former French Open semi-finalist, the seventh seed, broke Dementieva four times in the rain-interrupted match and will play another Russian, third seed Svetlana Kuznetsova, for a place in the last four.
Kuznetsova had a comfortable 6-3, 6-2 win over unseeded German Martina Mueller, ending hopes of a local success at the US$1.34mil clay court event.
“Every time it got to 30-30 she pulled the hammer out,'' Mueller said. “It was still a good week for me.''
The 39th-ranked Mueller was broken at 3-2 in the second set despite being 40-15 up.
“You just can't waste chances like that against a top-10 player,'' Mueller said.
Serbian teenager Ana Ivanovic also went through to the last eight yesterday. The number 12 seed was leading Alona Bondarenko 6-3, 5-0 when the Ukrainian sprained her ankle and was forced to retire.
