The matchup between Ivo Karlovic/Martina Hingis and Feliciano Lopez/Jelena Jankovic could be decided between serve and volleys. Both teams have powerful serving men, with the ladies exuding their soft hands at the net. Besides, these pairs will carry on their missed doubles experience onto the court, which will further add to the excitement. Don’t be surprised to see the point starting with a huge serve and ending with an exquisite volley. Tough to pick a winner here.
