Thailand's Danai Udomchoke upset top favorite Lee Hyung Taik from South Korea in the men's singles final at the Asiad on Thursday.

Top seeded Lee, who won a gold medal on December 8 with South Korea in the men's team event, entered the final as the clear favorite through his world ranking of 49.

With the defending champion Paradorn Srichaphan from Thailand out of the tournament due to a wrist injury, Lee looked on course to pick up the gold. But another Thai, Danai Udomchoke, rose to the occasion.

Lee, who suffered a bad fever on Tuesday, did not have the stamina to match 104th-ranked Udomchoke before losing at 7-5, 6-3.

"The fever came after my match against Mamiit (in the semifinal on Tuesday). I even thought I might not be able to play today. I lost in the end, but I did my best," Lee said.
