Hello
However, it was the end of the road for the other Indians in the fray.
The BWF this month temporarily banned the serve, which involves a player spinning the shuttle before launching it, after it proved to be tough to return or completely unplayable.
It was also the Keralite's first title after the triumph in the 2017 US Open.
The rally took place in the decider and lasted for almost four minutes.
The ban will be in place for tournaments such as the BWF Sudirman Cup Finals which begin on Sunday in China and the Malaysia Masters the following week.
Praneeth went down fighting to China's world No. 23 Li Shi Feng in the men's singles quarterfinals.
This was Prannoy's second career win over Axelsen, whom he had beaten during the Indonesia Masters last year.
With two losses, Prannoy's chances of making it to the knockout stage is as good as over and rests on results of multiple calculations.
India's singles ace went down to the rising Japanese star in an hour-long contest.
He became only the fourth Indian to win a silver medal in the competition.
