Very aren't many obstacles Serena Williams hasn't been able to hurdle in her tennis career. However, the French Open's clay courts are one of them. Williams dispatched Sorana Cirstea on Friday to reach the round of 16 at Roland Garros for the first time since 2003. Now is as good a time as any to claim her second French Open title. Williams has now won 27 consecutive matches. At least things are going well for one WIlliams sister.
