(CNN)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 against Sabine Lisicki as she surrendered six straight games in the second set having won a tight opener.
But the American rallied to overcome the 21st-ranked German 7-6 1-6 6-3 in a little over two hours and celebrated with a hard-earned slice of cake.
"I had no idea," said Williams, who last year won a record seventh Miami title. "I saw them bringing out a cake and I thought, 'Whose birthday is it today?' But I really had no idea about (the milestone)."
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 1,442 match wins -- the leading mark in both the men's and women's game.
