WASHINGTON (AP) - Three-time champion Andy Roddick has pulled out of next week's Legg Mason Tennis Classic because of a partially torn abdominal muscle on his right side.
The tournament announced Roddick's withdrawal Thursday and said he was hurt while practicing.
"It's disappointing to lose a player of Andy's caliber, especially in light of his success and many years of participation throughout his career here in D.C.," tournament director Jeff Newman said in a statement.
"However, we are thrilled with our strong player field for the 2011 Legg Mason Tennis Classic, featuring two of the top ten players in the world in Gal Monfils and Mardy Fish and both of last year's finalists, with David Nalbandian and Marcos Baghdatis," he added.
Four other players are missing the hard-court tournament with injuries: two-time major champion Lleyton Hewitt, Sam Querrey, Milos Raonic and Kei Nishikori.
The highest-ranked players in the field are No. 7 Gael Monfils and No. 9 Mardy Fish.
