The three-day competition at Prague's O2 Arena pitted a team of the six best European players against the top six from the rest of the world.
Seen by some as a tennis version of the Ryder Cup in golf, the inaugural Laver Cup was played on an unusual black hard court.
Rafael Nadal, Alexander Zverev, Marin Cilic, Dominic Thiem and Tomas Berdych also formed the European team, while Sam Querrey, John Isner, Jack Sock, Denis Shapovalov and Frances Tiafoe played for the world.
The tournament is to honor Rod Laver, an 11-time major champion who won two calendar-year Grand Slams.
Chicago will host it in 2018.
