Djokovic quits due to shoulder, run ends (AP)
Novak Djokovic's remarkable winning streak ended with a grimace, one that puts a new spin on the U.S. Open. The world's top-ranked player was forced to retire in the second set Sunday because of a sore right shoulder, giving Andy Murray the championship at the Western & Southern Open. It was the Serb's first bad moment in his 57-2 season.
