Serena Williams beat Maria Sharapova, 6-4, 6-3 in 89 minutes in the WTA Tour Championship this weekend in Istanbul, Turkey, while Venus Williams beat Monica Niculescu 6-2, 6-3 last weekend to win her only title this year, the Luxembourg Cup in Luxembourg. Venus winning her 44th singles title puts her second only to her little sister Serena who holds 46, among active players. Serena finishes the year with a world ranking of No. 3 and Venus finishes at No. 24. Either sister would have more titles if they had not played each other in 8 Grand Slam and 3 other finals, with a career head to head record of 13-10.
Serena defeated all the top players this weekend again, however, she could only finish as high as No. 3 on the Women's Tennis Association (WTA) Rankings because of WTA rules based on her amount of play. According to the WTA, Serena has won 48 out of 50 of her last matches, winning all 18 of her last matches against the top players in the world: 1) Victoria Azarenka, 2) Maria Sharapova, 4) Agnieska Radwanska, 5) Angelique Kerber, 6) Sara Errani, 7) Li Na, 8) Petra Kvitova, and 10) Caroline Wozniacki.
