Andy Roddick ended a streak of 11 consecutive losses to Roger Federer on Thursday at the Sony Ericsson Open.

Dominating with his serve, Roddick took advantage of Federer's suddenly shaky play down the stretch to win 7-6 (4), 4-6, 6-3 in the quarterfinals. 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 delighted capacity crowd afterward. "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.

The top-ranked Federer was broken for the only time at love to fall behind 5-3. Roddick closed out the victory with a 140-mph service winner.
