Buoyed by a stellar start and a fantastic finish in a rematch of last year's final, Federer beat Djokovic 6-3, 5-7, 7-5, 6-2 Saturday to move one victory from a fifth consecutive U.S. Open championship and 13th Grand Slam title overall.
He wasn't going to know until Sunday at the earliest who would be his next opponent. Tropical Storm Hanna hit the New York area in the afternoon, dumping enough rain to force the suspension of the semifinal between No. 1 Rafael Nadal and No. 6 Andy Murray in the third set.
The weather also forced the postponement of the women's championship match between Serena Williams and Jelena Jankovic, originally scheduled for Saturday night. Instead, that will be played Sunday.
