World No. 1 tennis player Victoria Azarenka, of Belarus, has agreed to a multi-year endorsement deal with Red Bull, which makes her "the first tennis player signed by the beverage giant," according to Kristi Dosh of ESPN. The deal adds to Azarenka's "growing stable of corporate partners," which includes Citizen Watch, American Express, Six Star Nutrition and Wilson. Azarenka joins Red Bull’s growing list of athletes outside of the action sports world.
