Europe won the Laver Cup for the third time downing Team World 13-11 after Alexander Zverev beat Milos Raonic in the decider.
In a much closer contest than the first two runnings of the competition, Zverev and Raonic split the two sets leading to a match tie-break.
Zverev received words of advice from Roger Federer and Rafa Nadal before the sudden death stanza and led throughout eventually clinching it 10-4.
The World team were a match away from victory when they won the first two matches of Sunday, as John Isner and Jack Sock beat Federer and Stefanos Tsitsipas and Taylor Fritz overcame Dominic Thiem, both on match tie-breaks.
Federer beat fatigue to down Isner in two sets to set up the decider and then Zverev, for the second year in succession, was the man who got Team Europe to the magic 13-point mark.
"It was an unbelievable weekend - they [Team World] were one or two points away from winning it all," Zverev said.
"Hopefully many of you will play Laver Cup many times but it was an incredible weekend.
"Those guys were screaming at me in the locker room before the tie-break," Zverev continued. "They told me this is how I can turn my season around and get my confidence back.
"I'm super happy and super thankful to Rafa, Roger and the rest of the team. Without them on the bench, I wouldn't have done it.
"This is very special, especially them guys trusting me to play the last singles match we have. It's an unbelievable feeling.
"This event is something I hope to play every single year of my career."
Europe won the inaugural Laver Cup 15-9 in 2017, then retained the cup last year winning 13-8.
