Lee Zii Jia overcame Kodai Naraoka in an epic Australian Open men's singles champion to capture his second World Tour title this year on Sunday.

Giving everything he had against the second seeded Japanese, Lee secured the hard fought 21-19, 11-21, 21-18 victory after 78-minutes of action in Sydney.

His latest success comes on the back of his Thailand Open title last month, which he followed up by reaching the Malaysia Masters final a week later.

Lee's victory in this Super 500 event will also bump him up the world rankings and give him a better seeding at next month's Paris Olympics.

Finishing his final warm-up event before the Olympics as champion will give Lee the perfect tonic to launch his charge at the Paris spectacle, where he has already started his intent to bring home the gold medal.

The manner in which he recovered from a slow start to eventually see off the stiff challenge from Naraoka in the deciding game will also give the world number eight the confidence that he can deal with pressure cooker situations and come out tops.

Lai Pei Jing-Lim Chiew Sien did their best, but couldn't ensure Malaysia came home with two titles after they lost 21-12, 7-21, 13-21 against Indonesia's Febriana Dwipuji-Amallia Cahaya in the women's doubles final.
