CHICAGO (AP) Roger Federer and Novak Djokovic have played against each other 46 times. From Monaco to Shanghai and everywhere in between. Regular, run-of-the-mill tournaments and major finals.
On Friday night, they play on the same side of the net for the first time.
Federer and Djokovic will close out the first day of the second edition of the Laver Cup when they take on Jack Sock and Kevin Anderson in doubles at the United Center. Federer and Djokovic are playing for Team Europe, while Sock and Anderson are competing for Team World in the Ryder Cup-style event.
