In what may be an omen for the rest of the season, Novak Djokovic topped Rafael Nadal, 6-2, 7-6 (4) on Sunday and then clinched the ATP Cup for Serbia in doubles. He has now beaten Nadal 29 times in 55 meetings. 

Before the match, it was all love between the two rivals. 

As if that wasn't enough, Djokoic headed back into the locker rooms after his match to join Victor Troicki for the doubles battle against Pablo Carreno Busta and Feliciano Lopez. 

With the victory, Djokovic is now the only player to be part of the winning team in the Davis Cup, Laver Cup and ATP Cup. He also finished the tournament undefeated in singles, picking up 665 points to close the gap between himself and Nadal to 515 pints.
