Novak Djokovic couldn't go on and, now, neither will Serbia.
The world No. 1 retired early in his Davis Cup match Sunday against Juan Martin Del Potro with the same back injury that affected him during the U.S. Open. Djokovic's retirement gave Argentina an insurmountable 3-1 lead in the nation's Davis Cup semifinal. Serbia was the defending champion in the event.
Djokovic cried in the arms of his teammates after making the decision. "I feel disappointed to end this tie this way," he told reporters. "My condition was 60 percent of what I had expected."
It was the Davis Cup win last year that ignited Djokovic's historic 2011. He said Sunday that his back was hurting before the U.S. Open and particularly affected him during the final. Djokovic pulled out of his first singles tie on Friday but tried to go on Sunday to even the tie and force a fifth and deciding final match.
