PARIS, May 10 (Reuters) - French tennis player Richard Gasquet tested positive for cocaine at a tournament in Miami last month, the world number 23 said on Sunday.

"The B sample test from March 2009, during the Miami tournament, in which I did not take part, confirms the positive results from the A sample," he said in a statement read out on French radio RTL.

Gasquet said he had a hair sample tested by an independent lab "which showed no trace of cocaine".
