Team Europe have defeated Team World 15-9 to win the inaugural Laver Cup.
Roger Federer got the decisive win over Nick Kyrgios in Prague, coming from a set down and saving a match point to prevail 4-6 7-6 (8/6) 11-9 in a thrilling three-set match.
Kyrgios got the only break of serve in the first set early on but soon found himself a break down at the beginning of the second. However, after a medical time out the Australian broke back and took it to a tie-break.
He saved three set points in the breaker but 19-time grand slam champion Federer eventually levelled things up.
The players could not be split in the deciding set and it went to a champions tie-break, which Kyrgios led 6-2 at one point. But Federer battled back and Team Europe got the point they needed for victory when Kyrgios sent a forehand into the net.
Team World had clawed their way back into the tournament on Sunday with a win in the doubles match, while John Isner beat Rafael Nadal 7-5 7-6 (7/1).
Had Kyrgios defeated Federer to tie the tournament, the final doubles showdown would have decided the winner of the Laver Cup.
