Meanwhile, in results so far, India's Sarath Dunna ed a major upset Tuesday defeating Yehezkiel Fritz Mainaky ranked almost 600 places above him in a thrilling men's singles encounter to win it 21-9, 17-21, 21-16. Also, 3rd seed Rahul Yadav Chittaboina got off to a strong start, getting the better of compatriot Aneeth Kumar Repudi in straight games of 21-11,21-12.
