Su-Wei Hsieh grabs Malaysia quarter-finals spot

World number five and top seed Agnieszka Radwanska may have to wait another day to finish her first round match in the BMW Malaysian Open after rain again stopped play on Wednesday.

The Polish player, who won in Dubai last week, was leading Akgul Amanmuradova of Uzbekistan 6-2, 3-3 when rain interrupted play. The match had failed to get under way on Tuesday due to heavy rain and lightning.

Her likely quarter-final opponent is Taiwan's Su-Wei Hsieh, who beat Casey Dellacqua 6-1, 7-5.

Hsieh, who made it through from the qualifying round a day earlier, said she was a little surprised at the ease of her victory as she was suffering from jetlag after arriving in Malaysia from Dubai early Sunday.

"I didn't have much sleep the last two days and in fact took advantage of the three-hour rain delay to get some much needed rest," Hsieh said.

"My body still adjusting, and I'm just happy to get to the quarter-finals."

Dellacqua of Australia ranks 107th in the world, while Hsieh is 123rd in world rankings.

Also through to the next round is fifth seed Petra Martic, who overcame a three-hour rain delay before finally taming Kurumi Nara of Japan 6-2, 3-6, 6-0.

The $220,000 BMW Malaysian Open at the Bukit Kiara Equestrian and Country Resort will end on Sunday.
