With superior offense and defense, Novak Djokovic earned his fourth Key Biscayne title on Sunday, beating Rafael Nadal who failed again trying for his first. Djokovic took charge midway through the first set and closed out the victory by winning a remarkable exchange to beat Nadal 6-3, 6-3 in the final of the Sony Open. Djokovic said "This tournament has been perfect from the beginning to the end. The matches that I have played I played really well, and I elevated my game as the tournament progressed. The best performance of the tournament came in the right moment on Sunday, against the biggest rival.''
