Novak equals Agassi record

Top seed Novak Djokovic continued his domination of men's tennis with a 6-3 6-3 win over Japan's Kei Nishikori in the Miami Open final in Florida on Sunday, before quickly turning his thoughts to the upcoming clay court season.

The French Open is the only grand slam missing from Djokovic's otherwise glittering resume, but he has already been installed by the bookmakers as odds-on favourite for Roland Garros after a magnificent start to 2016.

Djokovic dropped serve in the first game against Nishikori but it was pretty much one-way traffic after that as he outclassed the sixth seed in all facets of the game on the hardcourt at Key Biscayne.

The 28-year-old Serb took 85 minutes to join American Andre Agassi as a six-time Miami Open winner.

Djokovic said his first Miami win in 2007 paved the way for a career that now includes 63 ATP titles.

"It gave me a lot of confidence, a lot of self belief that I can finally win these big tournaments, finally beat the top players," he said in a courtside interview.

He collected $1,028,300 on Sunday, becoming the sport's all-time leading money-winner with career earnings approaching $100 million.
