World number one Serena Williams will eye her sixth Wimbledon title when she takes on Garbine Muguruza of Spain at the Centre Court in London today. A victory will give Serena her 21st Grand Slam trophy, which will be one less than Steffi Graf's record of 22 Grand Slam titles in the Open Era, and Margaret Court's all-time record of 24. At the age of 33, the American could today also become the oldest female winner of a major in the Open Era.On the other hand, world number 20 Muguruza, who became the first Spanish woman to reach a Grand Slam Final in 15 years, will be looking to repeat her last year's French Open feat, when she defeated Serena in straight sets in the second round. If Garbine wins today, it will be her maiden Grand Slam title, as she has never made it past the quarterfinal stage in any Major event.In Women's Doubles, Sania Mirza will today leave no stone unturned to claim her maiden Grand Slam trophy. She and her Swiss teammate Martina Hingis, the top seeds, will meet the second placed Russian team of Ekaterina Makarova and Elena Vesnina.
