The 24-year-old triumphed 21-15, 14-21, 24-22 in the last four of the Super Series event at the Jakarta Convention Center.

It means he has set-up an all-unseeded final against Japan's Kazumasa Sakai.

The latter denied a second Indian a place in the showpiece game by beating Prannoy Kumar 17-21, 28-26, 21-16 in an epic clash.

Kumar had already knocked out top see Lee Chong Wei of Malaysia and China's Olympic champion Chen Long but his run was to come to an end.

In the women's singles, South Korea's fifth seed Sung Ji-hyun will meet unseeded Japanese Sayaka Sato in the final.

The Korean knocked out Zhang Beiwen of the United States in three games, 21-10, 8-21, 21-10.

Sato came through against Nitchaon Jindapol of Thailand, 13-21, 21-18, 21-14.

Both singles finals will be played tomorrow, along with the conclusion of the three doubles tournaments.
