Serbian teenager Novak Djokovic became the youngest winner of the Miami Masters after demolishing Guillermo Canas 6-3 6-2 6-4 in the final.
Djokovic has been tipped as a future world number one
The 19-year-old 10th seed dominated his Argentine opponent from start to finish to win in two hours, 19 minutes.
He is the first teenager to win the event since Andre Agassi defeated Stefan Edberg in 1990.
Djokovic will now rise to a career high world number seven when the rankings are released on Monday.
He claimed a total of six aces, converted four of seven break point opportunities and had just one double fault in the contest.
Djokovic, who lost serve just once in 59 games in the tournament, sealed the win with a forehand winner.
It was the second title of the season for Djokovic and the fourth of his career.
"When you play a final nothing is easy," said Djokovic. "I played unbelievable tennis in Indian Wells and here. It was the best tennis of my life. I didn't lose a set.
If he continues like this he will be one of the top three players very, very soon
"I'm always comparing myself to the best players in the world because that is what I want to be one day.
"Right now I feel like for the first time in my career that I am on that level, that I deserve to be one of the three best players in the world.
"I'm really happy with my achievement right now and hope this is only the start."
Canas, who beat Roger Federer for the second time in three weeks on the way to the final, was attempting to become only the second unseeded player to win this tournament.
"I tried my best it just wasn't enough to beat him," he said.
"He's a great player, very confident, he played great tennis these four weeks.
"If he continues like this he will be one of the top three players very, very soon."
Djokovic was helped in the first set when Canas was charged with a foot fault giving him triple break point which was immediately converted into a 3-1 lead.
He broke Canas early on in the second but the set swung on the sixth game which went to deuce eight times before the Serb finally held serve.
Canas continued to battle despite a thigh problem but he handed Djokovic the decisive break when he double-faulted at 4-4 allowing his opponent to serve out the match.
