Rome: : Andy Murray claims Juan Martin del Potro insulted his mother during a first-round match at the Rome Masters. “Someone saying something about your mother who is one of the nicest ladies you’re ever going to meet? I don’t think that’s really that cool,” Murray said after del Potro retired while trailing 5-7, 6-4, 1-0 late Monday. Judy Murray provided vocal support for her son from the stands during the match.
