It's getting hard to keep track of all the numbers and milestones she's piling up - sixth Wimbledon title, 21st Grand Slam title, second Serena Slam - but there's something else Serena Williams has done this week that has never, ever been done before, not even by Steffi Graf, not even by Margaret Court.
This is the first time No.1 has twice as many points as anyone else on the WTA Rankings.
According to WTA records, never before has the No.1 player on the WTA Rankings had twice as many, or in this case more than twice as many, points as No.2 or anyone else on the WTA Rankings.
And it makes sense - Williams has won the five biggest tournaments in the last 12 months, all four of the Grand Slams and the BNP Paribas WTA Finals Singapore presented by SC Global, and she even has one of the four tournaments at the next level, the Premier Mandatories, winning in Miami (the others went to Maria Sharapova at Beijing, Simona Halep at Indian Wells and Petra Kvitova at Madrid).
And here's a bonus stat: with 21, Williams now has just as many Grand Slam titles as all other active players combined (Venus Williams seven, Sharapova five, Victoria Azarenka, Svetlana Kuznetsova and Kvitova two each and Ana Ivanovic, Francesca Schiavone and Samantha Stosur one each).
