LOS ANGELES - Four-Time Grand Slam tennis champion Maria Sharapova will return to her roots working for US broadcaster NBC during the Sochi Winter Olympics in February. "Thrilled to be part of the NBC Olympic Broadcasting team at Sochi 2014 Winter Olympic Games," Sharapova said via Twitter Wednesday. NBC said the 26-year-old Sharapova would bring a unique insight to Russia's first Winter Games. "Maria transcends sports as one of the world's most recognizable stars," Jim Bell, Executive Producer of NBC Olympics, said in a statement. "Growing up in Sochi until she was six years old and with family and friends still living in the area, Maria will offer a unique and personal perspective on a place she knows so well." Sharapova was the flag-bearer for Russia at the 2012 London Summer Olympics. –AFP
