Beirun (Poland): Young Indian shuttler Rituparna Das clinched the Polish Open after defeating fellow Indian Rasika Raje in the women's final of the International challenge badminton event here on Sunday. Rituparna beat Rasika 11-21 21-7 21-17 in a 40-minute clash.

Women's doubles pair of Sanjana Santosh and Arathi Sara Sunil also clinched the title after defeating top seeds Natalya Voytsekh and Yelyzaveta Zharka 19-21, 21-19, 21-14 in the final that lasted more than an hour.

Sourabh Verna, however, lost his second final after Belgium Open following some tough contest in the finals against Denmark's Victor Svendsen.

The Indian, who is making a comeback after a series of injuries, fought a gruelling battle before going down 27-29 13-21 in the final.

On Saturday evening, Rasika had the most trying time at the court as she fought hard before notching up a 21-17, 28-26 win over Malaysia's Soniia Su ya Cheah.

Rituparna, however, didn't break a sweat as she dumped Julie Macpherson 21-11, 21-9 in a lop-sided semi-final contest. Sourabh too outclassed Zii Jia Lee, a qualifier, to set up a final clash with Victor.
