The 28-year-old Hong Kong shuttler lost the first game to Prannoy 17-21. But by staying patient in long rallies and choosing the right moment to strike, he won the remaining two games 21-9, 21-17.

The 28-year-old badminton ace is the only seeded player left in the men's singles event following the exits of defending champion Kento Momota and Chou Tien-chen in earlier rounds.

Ng -- seeking his second Malaysia Masters title after winning in 2017, said being patient was his secret weapon.

"When my form wasn't good before, I was rushing to get results to make up for it. But being impatient did not pay off. I just had to tell myself to be patient and work hard in training and trust in the process.

"I am relieved to have made this final. I will give my best tomorrow (Sunday) and hopefully it will be enough," he said.

Ng's opponent in the final is Indonesian Chico Aura Dwi Wardoyo who qualified after an earlier victory over China's Lu Guang Zu.
