KEY BISCAYNE, Fla. -- Top-ranked Novak Djokovic won his third Sony Ericsson Open title Sunday, holding every service game to beat Andy Murray, 6-1, 7-6 (5).
Djokovic also won in 2007 and last year. Only six-time champion Pete Sampras has won more men's titles.
The lone break point Djokovic faced came in the fifth game, and he erased that. In the tiebreaker he lost only one service point, went ahead to stay when Murray double-faulted to make it 3-2, and closed out the victory when the Scotsman sailed his final forehand long.
Djokovic didn't lose a set in six rounds, and saved 25 of 30 break points against him.
"I had a great tournament," Djokovic said. "I managed to play my best tennis when I needed to."
He improved to 20-2 this year and 90-8 since the start of 2011. He has won five Grand Slam titles, including the last three in a row.
Now begins the clay season culminating with the French Open, the only major event Djokovic has yet to win.
The No. 4-seeded Murray was fresh but rusty after needing only three matches to reach the final. He advanced twice due to walkovers, and was playing for the first time since Wednesday, which may have explained his slow start.
"That's why he's right at the top -- he always comes back, even if you feel you have control of the match," Djokovic said. "I'm really happy to close it out in straight sets."
