Maria Sharapova knows what it feels like to win. She also knows what it feels like to be a champion, having won the 2012 French Open to complete her career Grand Slam (Wimbledon, US Open, French Open and Australian Open).
To put that into perspective, winning a Grand Slam in tennis is like winning the Super Bowl four times in your career. It is something that only 10 women have ever accomplished.
It is truly one of the most incredible feats in tennis history.
