Olympic hopeful B Sai Praneeth suffered a straight game loss to Malaysia's Lee Zii Jia in the quarterfinals as Indian shuttlers had a dismal outing at the Swiss Open here on Friday.

Praneeth, who finished runner-up in the last edition, lost 14-21 17-21 to Jia in 45 minutes to bow out of the tournament. Ajay Jayaram's campaign ended after a demoralising 9-21 6-21 loss to eighth seeded Thai Kunlavut Vitidsarn in another last eight men's singles match.
