Tennis great Serena Williams racked up her 700th WTA win at the Miami Open on Wednesday, becoming the second player in as many days to be presented with a giant brightly colored cake after Andy Murray reached 500 wins on Tuesday.

World No.1 Williams looked to be heading for a surprise defeat as she surrendered six straight games in the second set having won a tight opener.

But the American rallied to overcome Germany's Sabine Lisicki 7-6 1-6 6-3 in a little over two hours and celebrated with a hard-earned slice of cake.

A 19-time grand slam winner, Williams has raked in more than $65 million in prize money.

It hasn't all been plain sailing however -- in 2010 doctors found a life threatening blood clot in her lungs resulting in the star taking a break from competition for 12 months.

Yet to lose a match in 2015, the reigning Australian and U.S. Open champion is writing her name across the history books, although she still has a long way to go to beat Martina Navratilova's record of 1442 match wins -- the leading mark in both the men's and women's game.

Williams' next match will see her up against world No.3 Simona Halep, the last player to defeat her in October last year.
