Maria Sharapova says that completing the career Grand Slam by winning Roland Garros was a notable achievement, but has not made her any less motivated to win other titles.

“I have had an incredible year so far,” the former world No. 1 told reporters at the U.S. Open. “Obviously winning the French was very meaningful to me. It was just one that I really wanted to get and to be part of my career whenever I ended. And, yeah, being there first time as an Olympian, going out there and getting silver, that was a great moment. Of course [the U.S. Open] is the last big one. This is kind of where you have to put all your energy. Even though it's not the last tournament of the year, you feel like this is where you can put all the work and effort into this one big event. It's very meaningful. It's big. It's New York City. There's no reason why I shouldn't perform my best here.”
