Maria Sharapova to report at Sochi

Maria Sharapova will trade her tennis racket for a microphone in a few weeks to join NBC for the Winter Olympics in her childhood home.

"Everyone seems to think I will be commentating on winter sports. I'm not a bobsledding expert," Sharapova told reporters Saturday after her 6-1, 7-6 (6) win over Alize Cornet in the third round of the Australian Open. "I will confirm I won't be commentating."

The four-time Grand Slam champion lived in Sochi until she was 6 and still has family and friends in the area. She was Russia's flag-bearer at the opening ceremony of the 2012 London Olympics, where she won a silver medal.

"I'm going to be showcasing the city of Sochi to a worldwide audience," she said. "I'm going to be with a few different co-hosts around the city, in the village and then I'm going to be doing a few segments in the studio."

The opening ceremony in Sochi is Feb. 7.

Sharpova next faces No. 20 Dominika Cibulkova at the Australian Open.
