Alexander Zverev completed Laver Cup victory for Team Europe after beating Milos Raonic in a final match decider.
After Taylor Fritz had given World an 11-7 lead by beating Dominic Thiem, Roger Federer gave Europe a lifeline when he defeated John Isner in straight sets.
That created a winner takes all battle between Zverev and Raonic in front of a sell-out crowd.
Zverev made the better start to the match and he got the crucial break to lead 4-2 when he hit a forehand winner.
And the German won the opening set when Raonic netted a backhand return.
But backed by strong support from his team-mates, Raonic recovered and broke a nervous Zverev to lead 4-2.
Serving for the set, Raonic was forced to save four break points before hitting an ace on his first set point to take the match into a ten-point tiebreak to decide the Laver Cup.
And in the breaker, buoyed on by the crowd, Zverev found a way to come through and complete a third consecutive win for Europe.
Zverev said: “It was an unbelievable weekend. They [Team World] were one or two points away from winning it all.
“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. 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.
“Of course, every single one of you guys [the crowd] too. I’ve never played in an atmosphere like that, it was unbelievable. You all deserve to win as much as I do.
“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. Maybe one day it will be back in Switzerland.”
