Key Biscayne, April 2:

Novak Djokovic succeeded where Roger Federer failed, and his reward was the Sony Ericsson Open title.

The precocious 19-year-old Serb beat Argentine qualifier Guillermo Canas 6-3, 6-2, 6-4 in Sunday’s final. Canas upset top-ranked Federer twice last month, including in the fourth round on Tuesday. But the 29-year-old’s relentless baseline game failed to faze Djokovic, who dominated with his versatile shotmaking and held every service game.

With his first ATP Masters Series title, Djokovic became the youngest men’s champion in the tournament’s 23-year history. He won every set he played — the first time the Key Biscayne men’s champion has done that since Ivan Lendl in 1989.

Canas can take consolation in a career resurgence. Ranked as high as eighth before serving a 15-month doping suspension that ended last summer, he was 143rd at the start of this year but will climb to about 31st in the new rankings.

Djokovic mixed pace, spins and angles so well that some of his shots were beyond reach even for Canas, whose forte is fetching. The slender Serb’s repertoire ranged from 130-mph serves to feathery drop shots, including one to end the match’s longest game. Djokovic earned $533,350 while Canas received $266,675.
