Anup Sridhar's dream run at the Singapore Open badminton championships came to an end after he lost to second seed Kenneth Jonassen of Denmark in straight games in the quarter-finals.

The Indian national champion, who upset some top players en route to his last eight appearance at the prestigious five-star event, failed to work his magic on the world No 6 and went down 15-21, 15-21 in 35 minutes.

Sridhar, ranked 43, had disposed of World No 20 Dicky Palyama in the first round before defeating Yi Lu of China and Andrew Smith of England [Images] to book a quarter-final berth.

But Jonassen, who has not dropped a game in the tournament so far, proved to be Sridhar's nemesis again, having beaten him twice earlier, including the recent straight games defeat in the quarter-finals of Thomas Cup in Tokyo.

With Sridhar's ouster, the Indian challenge at the US $170,000 event came to an end, as Saina Nehwal [Images] and Chetan Anand lost their second and third round battles in the women's and men's singles respectively on Thursday.

Sixteen-year-old Saina lost to seventh seed Petya Nedeltcheva of Bulgaria 21-11, 21-18 in the second round, while 13^th seeded Anand lost to Saman Ismail of Malaysia 18-21, 21-11, 15-21 in 49 minutes.

Anand had an easy outing against Jean Michel Lefort of France [Images] in the earlier round, wining 21-14, 21-19.

Although he did not have a title to show of for his efforts, Sridhar's performance in the Asian circuit has been creditable. He reached the pre-quarter-finals of the Indonesian Open last week, getting past the formidable Shoji Sato of Japan [Images] and Denmark's Bo Rafn, efforts that saw him jump 15 places in the world rankings to 43.

The quarter-final appearance at Singapore would further boost his rankings.

The Indians will now take part in the Malaysian Open.
