Next it's Sharapova's turn. She's certainly popular round these parts and she needed that crowd support at times today. "What a week, last year I lost in the finals and I really wanted to go one better this time," Sharapova said. "Simona played great to day and I'm not sure how I pulled it out in the end.
"It was tough losing in the final last year and I knew I had to do a few things better to win this year, which thankfully I did."
Halep is first up on stage to receive her runner-up trophy before congratulating Sharapova and charming the crowd with a very humble speech.

Halep 1-0: Halep won the toss and elected to receive and it's a decision that reaps immediate dividends. A couple of early errors from Sharapova give her half a chance before a beautiful forehand return onto line brings first break points of the match. She only needs one bite of the cherry, taking the early break when a Sharapova forehand sails long.
Past encounters between the two have gone the way of the Russian, who won in Indian Wells and Beijing, in 2012. Since then, though, Halep has come on in leaps and bounds. In the past 12 months she has bounded up the rankings, picking up seven trophies along the way.
For someone who famously once described her own movement on a clay court as like a "cow on ice", Sharapova looks pretty confident on the surface nowadays. In fact, six of her last eight titles have come on the terre battue that she once so openly loathed and goes into the final riding high on a 10-match winning streak.
To get an idea of the challenge facing Halep in her first Premier mandatory final, since losing to Li Na in 2011 French Open semifinals, Sharapova has lost just three times. All three came at the hands of World No.1 Serena Williams.
