Roddick beats Federer in Miami quarters

WASHINGTON, April 3 (Xinhua) -- American Andy Roddick ended a 11-match straight losing streak to Roger Federer with a thrilling win at the ATP Sony Ericsson Open on Thursday.

With his big serve, six-seeded Roddick took advantage of Federer's sloppy play in the final set to win at 7-6(4), 4-6, 6-3 in the quarterfinals after a service winner. Roddick improved to 2-15 against his nemesis.

"I came in knowing that nobody has beaten me 12 times in a row," Roddick told the capacity crowd after the match. "So I had that on my side."

Serving at 3-3, love-30 in the final set, Roddick won the next 11 points, five of them thanks to unforced errors by Federer.
