Serena Williams Italian Open - Tennis Star Bests Victoria Azarenka To Take Home Title

World No. 1 Serena Williams increases her lead this week in the women's world tennis rankings and Sara Errani sets a personal best by moving to fifth. Williams ran her winning streak to a career-high 24 matches with a 6-1, 6-3 victory Sunday over Victoria Azarenka at the Italian Open. It was the fifth title this year for Williams, whose 51 WTA championships are sixth-most all-time. Monica Seles (53) is fifth on that list and Lindsay Davenport (55) is fourth. All are far behind the top three on the all-time list: Martina Navratilova(167), Chris Evert (157) and Steffi Graf (107)
