Comeback man Ajay Jayaram stormed into the semifinals of the USD 150,000 US Open with a straight game win over Korea's Heo Kwang Hee in the BWF World Tour Super 300 tournament here.

The 30-year-old Indian took half an hour to dispatch Hee 21-18 21-12 in a men's singles contest at the Fullerton Titan Gym. Jayaram, who was stretched in the first two rounds by Yun Kyu Lee and Ygor Coelho, will next face France's Mark Caljouw. Jayaram jumped to a 10-4 advantage in the opening round but Hee narrowed down the deficit to 9-10. However, the Indian again moved ahead slowly to 17-12 before comfortably grabbing the game.
