Novak Djokovic tamed world number one Rafa Nadal 6-3 6-3 to claim his fourth Miami Open title, denying the Spaniard a maiden win on the Miami hardcourts.
The Serb got off to a nervous start before moving 4-2 clear when a huge forehand clipped the back of the baseline in the sixth game.
He closed out the set after 40 minutes and tightened his grip further with another break at the start of the second, moving Nadal from side to side before firing a backhand winner into the space created.
Nadal fired a brilliant forehand winner down the line to stave off another break point at 3-1 down, but his hopes of finally landing a first Miami title were slipping away.
Djokovic attacked the Spaniard's serve once again at 5-3 to earn two more break points and converted his first match point in a stunning 30-shot rally that ended with a half-volley into the open court.
It was the second straight Masters series title for the second ranked Serb, who defeated Roger Federer two weeks ago in Indian Wells.
The Miami title continues to be one of the few to elude Nadal, who has now finished runnerup four times at Crandon Park, twice beaten in the final by Djokovic.
The 40th meeting between Nadal and Djokovic added another line to what has grown into one of tennis's great rivalries with the Spaniard holding a 22-18 edge.
Hingis' winning return
Martina Hingis made a winning return when the Swiss player and German partner Sabine Lisicki claimed the Miami Open doubles title on Sunday with a 4-6 6-4 (10-5) over Russian duo Ekaterina Makarova and Elena Vesnina.
The title was Hingis's first since winning the doubles in Doha in 2007.
Since retiring that year, Hingis, a former-world number one, has flirted with a doubles comebacks.
Last year the winner of five singles and nine doubles grand slam career titles attempted a return with Daniela Hantuchova but found little success, winning just three-of-five matches and falling in the first round of the U.S. Open.
Hingis launched a second comeback this season, losing in the first round of Indian Wells, but looked right at home on the Miami hardcourts, returning to the winner's circle at an event she won twice (1998-99).
