Croatia's Sandra Perkovic wins Olympic women's discus title for Croatia

LONDON - Sandra Perkovic of Croatia has won the women's discus throw at the London Olympics with a national record of 69.11 metres.

The 22-year-old Perkovic, who tested positive for methylhexanamine last year and served a six-month ban, took the lead in the second round Saturday with a mark of 68.11 and then improved it by one meter in the third round.

Darya Pishchalnikova of Russia took the silver at 67.56. She won the silver at the 2007 world championships but had the medal stripped in a sample tampering scandal and was banned until April of 2011.

World champion Li Yanfeng of China only had two successful attempts, but her first at 67.22 was good enough for bronze.
