Star Indian shuttler HS Prannoy suffered a straight-game loss to Hong Kong's Ng Ka Long Angus in the quarterfinals to end country's campaign at the Taipei Open Super 300 tournament on Friday. The world No. 9 Indian didn't quite find his rhythm, going down 19-21 8-21 to fifth seed Ka Long in a lop-sided contest. Coming into the match with a 6-5 head-to-head record, third seed Prannoy matched his rival in the beginning but as the match wore on, he crumbled. Both the shuttlers didn't yield much as they engaged in a tight game, leading to a close affair in the first part of the opening game.
