Andy Roddick has announced he is retiring from tennis after the U.S. Open ... leaving him plenty of free time to bang his hot model wife Brooklyn Decker.
Roddick -- who's only 30-years-old -- has reportedly made over $20 million in prize money during his career ... plus a FORTUNE in endorsement deals with Lacoste, Rolex, Lexus and American Express.
Roddick -- who famously won the U.S. Open in 2003 -- has been plagued with injuries during his 12-year career ... affecting his knees, ankles, shoulder and back.
Roddick is currently ranked #22 in the world and is scheduled to play his next round in the U.S. Open tomorrow night. Hopefully, Brooklyn will be there to cheer him on.
