Jorgensen, aiming to become the first European to win the title since his compatriot Peter Gade 16 years ago, said: "He is so strong physically but I proved that I can play to my world ranking."

Carolina Marin of Spain, last year's surprise winner at the world championships, also made a strong comeback from one game down to win her first Superseries title, beating third seed Saina Nehwal 16-21, 21-14, 21-7.

"I was making too many easy mistakes and my hand was really nervous at the start, but then I just wanted to enjoy it," said Marin.

China's first title came from the mixed doubles final. Zhang Nan/Zhao Yunlei beat three-time champions Tontowi Ahmad and Liliyana Natsir of Indonesia 21-10, 21-10.

Bao Yixin/Tang Yuanting also defeated Wang Xialoi/Yu Yang 21-14, 21-14 over 39 minutes in an all-Chinese women's doubles final.

China's hopes of winning a fourth title were dashed by Danish pair Mathias Boe/Carsten Mogensen in the men's final.

The No 2 seeds were in top form as Fu Haifen and Zhang Nan, playing his second final of the day, lost 21-17, 22-20.
