Djokovic, Sampras to pair up
Djokovic, the world's top-ranked player, also will play Mardy Fish in a singles match, and an opening singles match between two other players will be announced later for the event billed as the Los Angeles Tennis Challenge.
The three pro-set matches will be played days before the start of the BNP Paribas Open in Indian Wells, Calif. Fish and retired player and current broadcaster Justin Gimelstob are co-hosts.
Proceeds from the event will benefit charities of Gimelstob, Fish and Djokovic, along with Call of Cure and the Southern California Tennis Association's community initiatives.
