Serena Williams is trying to complete a Serena Slam, or four majors in a row, for the second time. Only one woman in the Open Era has won four in a row twice - who is it?

LONDON, England - There's an undeniable magnitude to what Serena Williams has been achieving over the last few years - since returning to No.1 in 2013 she's an astonishing 150-11, a near-perfect 34-3 against Top 10 players, and has won 20 WTA titles, tying her with the WTA legend, Billie Jean King.

But while those stats are fantastic, her performances at the majors are historic. She's won seven of the last 12, including the last three - the 2014 US Open, 2015 Australian Open and 2015 French Open.

And at Wimbledon, which kicks off in just a matter of days, Williams will be looking to complete a Serena Slam, or four majors in a row, for the second time in her career - she first did it over a decade ago by winning the 2002 French Open, 2002 Wimbledon, 2002 US Open and 2003 Australian Open.

She would be the second woman in the Open Era to do it twice, after Steffi Graf, who first won five straight (1988 Australian Open, 1988 French Open, 1988 Wimbledon, 1988 US Open, 1989 Australian Open) then four straight (1993 French Open, 1993 Wimbledon, 1993 US Open, 1994 Australian Open).

Lucie Safarova, Williams' opponent in the French Open final, has a lot of belief in the World No.1.

"Well, she's a great player," Safarova said of Williams. "She obviously has the experience, and she's won all those Grand Slams already, so I think she can do it, especially if she's playing her best tennis."

But despite being a five-time champion there, Williams was cautious when asked about Wimbledon.

"I haven't done great at Wimbledon the past two years, so I'm going to take it a day at a time there. My goal is just to do better there than I have the last couple of years, do one more and one more and one more. That's the one I have been struggling at, so hopefully I will be able to play a little better there.

"I mean, it's perfect for my game."

It's true, Wimbledon could have been kinder to Williams the last two years. After winning her first major since her year-long injury and illness lay-off there in 2012, she fell to giant-killer Sabine Lisicki in the fourth round there in 2013, then to another giant-killer, Alizé Cornet, in the third round last year.

But she's won it five times before, in 2002, 2003, 2009, 2010 and 2012, and if she lifts her sixth Venus Rosewater Dish in 2015, she'll have a pretty cool first - she'll be the first woman in the Open Era to win three of the four majors six times each (she's won six Australian Opens and six US Opens too).
