MASON, Ohio (AP) -- Andy Roddick says his recent struggles on the court are the result of a mild case of mononucleosis.

Roddick lost in the third round at Washington on Aug. 6, saying afterward that he didn't feel right. He withdrew from the Rogers Cup in Toronto and had blood tests to figure out why he was sluggish. He said Saturday that one of the tests came back positive for mononucleosis - a mild case.

Roddick's doctors told him he's probably had it for the last couple of months and should be just about over it. He practiced Saturday in preparation for the Cincinnati Masters next week.
