Illness forces Roddick withdrawal

World number eight Andy Roddick has been forced to withdraw from the Delray Beach International Tennis Championships due to illness.

The American had secured his 30th career title in Memphis on Sunday, but was pushed all the way in his 7-6 (9-7) 6-7 (11/13) 7-5 success over Milos Raonic, in a match lasting two hours and 36 minutes.
