Murray off to a fast start

The blood feud between Andy Murray and Juan Martin del Potro just got underway on Ashe. The last time they played, in Rome in May, del Potro did the unthinkable: He cracked wise on Murray's mother, Judy, who was in the stands for their first-round match on the clay. Then, del Potro retired at 0-1 in the third, left the court in tears and the two have not spoken since.

Said Murray of the meeting: "It is another tennis match for me. When I get on court I have got to put emotions aside. Whether I like Del Potro or not doesn't make any difference.

"I have known him since we were really young. I wasn't great friends with him before."

OK, then. We're on our way to a first set tiebreak here.
