It has been Andy Roddick’s week for breaking streaks.  One day after breaking an almost five-year, eleven match drought against Roger Federer, Roddick lost to Nikolay Davydenko 7-6 (5), 6-2 on Friday night, the first time he has ever lost the Russian.   He was 5-0 against him before this semifinal match at the Sony Ericsson Open in Miami.  Roddick and James Blake will lead the U.S. team in singles against France starting Friday, April 10.
