TORONTO (Reuters) - Eighth seed American Andy Roddick has pulled out of the Toronto Masters because of illness, the ATP Tour said on Tuesday.
A winner in Canada in 2003, Roddick's place in the draw will be taken by lucky loser Paul-Henri Mathieu of France.
Chile's Fernando Gonzalez has also withdrawn due to a left calf injury. He will be replaced by Somdev Devvarman of India.
With the U.S. Open looming, Roddick's illness is more bad news for American tennis which, for the first time since the ATP rankings began in 1973, has no players in the top 10 after Roddick slipped to number 11 after his loss in Washington.
