Germany's Alexander Zverev beat South African Kevin Anderson 6-7 (3-7) 7-5 10-7 as Team Europe completed victory over Team World on the final day of the Laver Cup exhibition event in Chicago.
Roger Federer also beat John Isner 6-7 (5-7) 7-6 (10-8) 10-7 as Europe retained the trophy 13-8.
Earlier Federer and Zverev had lost their doubles rubber to Isner and fellow American Jack Sock.
Europe led 7-5 overnight, with three points for a win on the final day.
That meant Isner and Sock's opening 4-6 7-6 (7-2) 11-9 win in Sunday's doubles edged Team World in front 8-7 before Swiss great Federer, the world number two, and Zverev, world ranked five, swung things decisively in Europe's favour.
