Novak Djokovic celebrated several important milestones on Sunday 3 April, with a comfortable straight-sets victory over Kei Nishikori at Crandon Park sealing a sixth Miami Open crown and his third in successive years. That 6-3, 6-3 triumph also saw the dominant Serb pass rival Roger Federer as the ATP Tour's highest prize-money winner with estimated career earnings of over $98m (£68.8m, €85m).

As if that was not quite enough, Djokovic's 28th ATP World Tour Masters 1000 title takes him one above Rafael Nadal for the all-time lead and four ahead of Federer. Only Andre Agassi, who claimed 17 such trophies before retiring a decade ago, can match his exploits in Miami after winning six times overall including three in a row between 2001-04.

"Every year that I come back to Miami I do go through those memories from back in 2007 [the year of his maiden Miami Open victory]," the 28-year-old said afterwards. "It was the first Masters 1000 I won and opened a lot of doors for me. It gave me a lot of self-belief. I started to realise that I'm able to win the big trophies and to beat the best players in the world.

"So of course this is a [special] place for me to come back to, now winning it six times. Obviously I don't take any win for granted and especially in the big ones. So it was my best performance of the tournament. It came at the right time against a great quality player."

Nishikori added: "It was a really tough one. He has great defence, so it's tough to break his game. And it was windy. So I couldn't really be too aggressive because the ball was moving and it was tough to do that. He was very patient and he didn't miss. It's always so tough to play Novak."

In the women's event, Victoria Azarenka returned to the top five of the WTA rankings with a 6-3, 6-2 victory over Russian Svetlana Kuznetsova on Saturday (2 April). It was the second Miami Open title for the former number one and her first since beating Serena Williams back in 2009. Pierre-Hugues Herbert and Nicolas Mahut followed up their success at Indian Wells by beating Raven Klaasen and Rajeev Ram in the men's doubles. The women's doubles were won by Bethanie Mattek-Sands and Lucie Safarova, who eased past Timea Babos and Yaroslava Shvedova.
