The seasoned Vittinghus survived a tight opening game to account for India’s Srikanth Kidambi 22-20, 21-13 in the first semi-final of the men’s singles.

But South Korea’s Jeon needed three games over almost 70 minutes before subduing Indonesia’s Anthony Sinisuka Ginting 21-19, 16-21, 21-19.

The 19-year-old Ginting upset Chinese world No.2 and top seed Chen Long on Friday to reach the semi-finals.

Vittinghus, 30, ranked 12, was a member of the victorious Danish team of the Thomas Cup in Kunshan in China last month and now gets his chance of winning the last Superseries event before the Rio Olympics.

India’s Saina Nehwal will play China’s Sun Yu in Sunday’s women’s singles final.

Nehwal, a former world No.1 now ranked eight, got past the tournament Chinese fourth seed Wang Yihan 21-8, 21-12 and will be chasing her 22nd career title in Sydney.

Sun Yu won the other all-Chinese semi-final against third seed Li Xuerui 21-18, 21-19 and will be after her fifth career title.
