A game sixth seed, Nupur Santra (Rlys), took the national champion the full length before going down. Baboor clinched a semi-final slot with a 17-21 21-8 21-6 13-21 21-18 score and will now play dark horse, Railways' Bhushan Thakur, the third seed.

Thakur, going from strength to strength this season, stopped rising junior star Anal Kashyap (PSCB) 21-10 16-21 17-21 21-15 21-14.

Arjun Dutta (PSCB) booked the third semis berth with a 21-15 21-10 17-21 21-18 win over Anupam Kanwar (Assam). The last quarter-final will pit Subhajit Saha (Bng) against No 2 seed Arup Basak (PSCB).

The women's semi-final line will play Anindita Chakaravarty against N Arul Selvi (TN)and MS Mythili (PSCB) against Mouma Das (Bng).

No 2 seed Mythili got the better of fifth seed Montu Ghosh (Rlys) 21-13 21-19 21-18 while Selvi continued her remarkable consistency that sees her among the top 10 women in the country for over a decade. The sixth seed put paid to the young Bengal challenger Paulomi Ghatak 21-17 21-15 12-21 21-14.Indu, fresh from her success at the Northern India championships at Lucknow, played an error-prone game and paid the penalty.

She put down fatigue -- a consequence of a very hectic schedule -- as a factor. There was no detracting from Anandita's consistency that had the top seed struggling to find her rhythm throughout.
