Nadal has now won a record 31 Masters 1000 titles and will remain atop the world rankings.
MONACO (AP) Rafael Nadal won a record 31st Masters title after beating Kei Nishikori 6-3, 6-2 in the Monte Carlo Masters final on Sunday.
Nadal also became the first male tennis player in the Open era to win the same title 11 times - 13 years after his first title here.
It gave him a 76th title overall and ensured the Spaniard keeps his top ranking ahead of Roger Federer.
Nishikori was chasing a first Masters title, but the Japanese player took 11 minutes to hold for 1-1.
He got some brief hope, breaking Nadal with a superb passing shot at full stretch to lead 2-1, but meekly surrendered the next four games.
The second set was a procession and Nadal won on his first match point with a stinging backhand winner.
