NONTHABURI, Thailand -- U.S. Open champion Andy Roddick withdrew from the Thailand Open on Monday.
Roddick, the world No. 2, sent organizers a letter saying he injured his right hamstring in a Davis Cup match on Friday and had been advised by his doctor to rest for a week, according to Weller Evans, ATP executive vice president of players services.
"Obviously, everybody is disappointed that Andy will not be participating -- with the possible exception of the other players," Evans said.
On Friday, Roddick lost to Slovakia's Dominik Hrbaty in four sets in Davis Cup play. Roddick came back on Sunday to beat Karol Beck in straight sets, as the Americans beat Slovakia 3-2 in Bratislava to remain in the top tier of Davis Cup next season.
Evans said the ATP would fine Roddick $40,000 for withdrawing.
Top-ranked Juan Carlos Ferrero, the French Open champion, and sixth-ranked Carlos Moya, both from Spain, were scheduled to play Wednesday.
