"I last played him in 2014 so it's been quite a long time and I was really well prepared with my strategy," said the 23-year-old from Guntur, who had come into the match with a 1-2 head-to-head record against Jorgensen.
"My attack really worked. If I have the chance to kill the shuttle I am really going for it otherwise I'm really happy to make the long rallies," he said.
"I was really happy to kill those crucial three points in the end.

"My strategy worked really well at that particular moment. It happens in every match that the opponent starts reading your game and it only depends on how well you get back. I think I was really fast and quick and I didn't give him any big leads at that particular moment."
"I really don't want to take too much pressure, force the pace and make too many mistakes. I wanted to play safe and not give too many easy points away.
