India 's Kidambi Srikanth overcame compatriot Sai Praneeth 25-23, 21-17 to reach the semi-finals of badminton 's Australian Open in Sydney on Friday.

It will be Srikanth 's third straight Superseries semi-final, a turnaround from his modest form of last season.

"It's going great so far, I just want to play well," he said.

"I missed six-seven tournaments last year, I just want to play as many games as possible.”

After a close first game, Praneeth faltered in not maintaining the pressure on Srikanth , who steadily grew in confidence and closed out the match and will face China's Shi Yuqi in Saturday's semi-finals.
