Roddick cites injury, pulls out of match

ST. LOUIS -- Andy Roddick has withdrawn from a World Team Tennis match in St. Louis, citing a lingering injury.

Roddick was scheduled to play Saturday for the St. Louis Aces in a match against Kansas City. Aces general manager Dani Apted says Roddick's injury is too severe for him to play or travel to St. Louis.

In a statement, Roddick said he's been dealing with the injury since mid-May. He did not specify the injury.

Roddick, the sixth seed at Wimbledon, was upset in the second round.
