Roddick loses out to Argentine starlet

Andy Roddick was defeated in Los Angeles as Argentina's Juan Martin del Potro secured his third consecutive tournament victory.

The former world number one, who snubbed a place on America's Olympic team in order to stay at home and prepare for the US Open later this month, has been struggling with a back problem and required treatment on it during the first set.
However Roddick refused to use that as an excuse as 6ft 6in 19-year-old Del Potro followed up his back-to-back clay titles in Stuttgart and Kitzbuhel last month to ease to a 6-1 7-6 (7-2) victory on the LA hard courts.
Del Potro, who is set to climb the rankings again after jumping up to a career-high 24 recently, said: "I played a very good week and today I played unbelievable.
"I don't think Roddick was 100% but I played unbelievable to win. I beat (Tommy) Robredo last year but to beat Roddick in the United States, I think is the best win of my career."
Roddick said: "I could have played really well but I am not sure it would have mattered. I missed a few returns but other than that I was okay."
