(Newser) – 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. Roddick's opponent in the semifinals Friday night will be No. 4 Nikolay Davydenko.

In the women's semifinals, Serena Williams overcame a slow start to outlast Svetlana Kuznetsova 3-6, 7-5, 6-3. Williams needs one more win for her fifth Key Biscayne title and second in a row. "I haven't won anything five times, except I win all the time in Uno," Williams said. "I don't think that counts."
