There were two upsets in the men's section with No. 9 seed Devesh Karia of CRSB and No. 13 Sourav Chakraborty of PSPB lost to unseeded Sivananda Seshadri of FCI and Souvik Basu Roy of RSPB respectively.
However, it was a smooth sailing for holder Anthony Amalraj, runner-up Achanta Sharath Kamal and other seeds.
An excellent draw in women's fare ensured that out of 16 matches, only four ended with straight set results while four went the full distance.
However, No. 4 seed and Olympian Ankita Das and No. 8 Mamata Prabhu snathed victory from the jaws of defeat to move to the pre-quarterfinals along with the rest.
It was a remarkable recovery by Ankita Das against AV Nivedita of the Airports Authority of India. The latter poised for an upset with a 3-1 lead, but some silly mistakes in the fifth game gave the much-needed breathing space for the Siliguri girl. Seizing the opportunity, Ankita inched close to one of her best comeback 9-11, 7-11, 11-3, 11-7, 11-6, 5-11, 11-7 wins in recent times.
Mamata, on the other hand, was down 0-3 against PSPB
