Sharapova not done yet

Maria Sharapova insists there is still more to come after her "unique" experience of winning all four Grand Slams.

The 25-year-old completed the set with a straight sets victory over Sara Errani in the final of the French Open on Saturday to add to her Wimbledon triumph (2004), US Open victory (2006) and Australian Open success (2008).
The Florida resident has managed to emerge from winning the SW19 title at such a young age to enjoy a long and fruitful career but has had to battle with injury and dips in form along the way.
But she is now back to her best, having made the Wimbledon final last year and the final at Melbourne Park earlier in 2012, and admitted that taking the Roland Garros title was right up there with anything she has achieved in the sport.
"It's the most unique moment I've experienced in my career. I never thought I would have that," she said.
"I thought that when I won Wimbledon at 17, that would be the most treasured moment of my career. But when I fell down on my knees today I realised that this was extremely special, and even more so."
Sharapova missed 10 months of action in 2008 and 2009 and there were rumours that she would not return to the sport due to a serious shoulder injury, but she fought back from adversity and will be installed as the new world number one when the rankings are announced on Monday.
The Nyagan-born star has achieved a great deal in the game over a lengthy period but, only in her mid-twenties, she is targeting many more titles before hanging up her racket.
"I have a lot more in me to achieve," she added. "I believe in my game. I think that's one of the reasons why I'm sitting here with my fourth one and winning Roland Garros, is because I always believed I could be better, I could be a better player, whether it was on clay, grass, cement, anything, I always strive to be better."
