DUESSELDORF, Germany (AP) — Andy Roddick, the highest-ranked American man, withdrew from the French Open on Monday because of a right shoulder injury.

The sixth-ranked Roddick, who lost in the first round at Roland Garros the last two years, pulled out of the semifinals of the Rome Masters on May 10. He then skipped the Hamburg Masters last week but had been expected to play this week at the World Team Cup in Duesseldorf.

"Andy is pulling out with an upper back shoulder injury, the same thing that he had in Rome," said John Roddick, Andy's brother and the U.S. captain at the World Team Cup. "He's pulling out of here and he's also going to miss the French Open, too."

John Roddick said he hoped his brother would be ready for the grass-court tournament at Queen's Club, a key warmup for Wimbledon.
