Radwanska withdraws from Malaysian Open
Top seed Agnieszka Radwanska has withdrawn from the Malaysian Open through injury.
The Polish world number five had been forced to complete two matches in one day on Thursday due to rain disruptions in Kuala Lumpur.
A WTA spokesman confirmed that Radwanska, who reached a career-high ranking after her tournament win in Dubai last week, had sustained an injury to her right elbow.
"I'm so sorry I can't continue. Had a great time in Malaysia and I hope to be back in future," Radwanska said as she conceded her quarter-final match-up with Taiwanese qualifier Hseih Su-Wei.
Hseih will face either Greece's Eleni Daniilidou or Australian Olivia Rogowska in the semi-finals. Daniilidou was leading their quarter-final 6-2 3-2 when rain once again caused play to be suspended.
In the other half of the draw fifth seed Petra Martic upset third seed Peng Shuai of China 4-6 7-6(7) 6-4.
