Indian shuttler Parupalli Kashyap played his heart out before going down fighting to world number two Lee Chong Wei in a gruelling quarterfinal of the men's singles event at the London Olympics here today.

Kashyap dived, smashed, retrieved almost everything thrown at him but still could not stop the top seed Malaysian as he eked out a 21-19 21-11 victory to advance to the semi-finals at the Wembley Areana here.
