Team World thrashed Team Europe 13-2 to win the Laver Cup for a second successive year in Vancouver.
Americans Ben Shelton and Frances Tiafoe beat Poland's Hubert Hurkacz and Russia's Andrey Rublev 7-6 (7-4) 7-6 (7-5) in the doubles to triumph.
Team World dominated the tournament and only needed to win the doubles match to secure the trophy.
Norwegian Casper Ruud's win over American Tommy Paul on Saturday sealed Europe's only points.
With the winner being the first team to reach 13 points, Team World were on track after day one having won all four matches before Americans Taylor Fritz and Tiafoe both won in straight sets on Saturday and Felix Auger-Aliassime, of Canada, and Shelton added a doubles win to carry a 10-2 lead into the final day.
