India's HS Prannoy stunned Tommy Sugiarto in straight games to sail into the men's singles quarterfinals even as his compatriot B Sai Praneeth crashed out in the second round of the New Zealand Open badminton tournament here Thursday. Unseeded Prannoy shocked second seed Sugiarto 21-14 21-12 in just 37 minutes to book his place in the last-eight round, where he will be up against fifth seed Kanta Tsuneyama of Japan.

This was world no. 26 Prannoy's maiden meeting against world no. 13 Sugiarto. Earlier in the day, Praneeth suffered a straight-game 12-21 12-21 loss to the legendary Lin Dan of China. Seventh seed Lin Dan, thus, progressed to the quarterfinals where he will be up against top seed Anthony Sinisuka Ginting of Indonesia.
