In preparation for the 2012 Olympic Games in London, we're profiling 20 of the top medal contenders.

Maria Sharapova left Paris last month with the Roland Garros title in hand—and a memorable text message embedded on her cell phone. Following her third-round win at the French Open, Sharapova received a request asking her to carrying the Russian flag during the Olympic opening ceremonies.

“I had to read the text message five times and read it to other people to make sure I got it correct,” said Sharapova. “I am so honored, and especially excited as it will be my first Olympics. It’s something I've dreamed of since I was a young girl, so I really can't wait.”

The 2004 Wimbledon champion will be a favorite to win a medal on the lawns of SW19, and her Olympic experience might include the Winter Games as well: Sharapova served as an ambassador for her former home city of Sochi’s successful bid to host the 2014 Winter Games, which she may attend.
