Wimbledon 2013: Maria Sharapova advances to second round after defeating Kristina Mladenovic I knew that my opponent was capable of playing really great tennis. I tried to take my opportunities in the tie-break. I was happy with the way I stepped up in the second set. It's always nice when you're not breaking somebody to get ahead and win that tie breaker. It was still pretty tough in the end but I'm glad I got it done in two. The build-up to Wimbledon was dominated by a very public spat between Sharapova and world number one Serena Williams, who beat the Russian in the French Open final. Sharapova blasted the defending champion for her controversial comments over a high-profile rape case and a perceived slight against her relationship with Bulgarian player, Grigor Dimitrov. Laying bare the bitter rivalry between the two, the Siberian dished some back, ripping into the American's colourful private life and telling Williams to keep her opinions to herself. With Mladenovic seen off, Sharapova faces either Portuguese qualifier Michelle Larcher de Brito or Melanie Oudin of the United States in the second round.
