That meant a total of 13-11 after three days of tennis in Geneva, Switzerland, and Borg's European team has now won all three editions of the tournament.
But if the ending was celebrated with wild cheering among the European stars, the start of Sunday was the gloomier. First, Rafael Nadal had to pull out of the match with a hand injury. Subsequently, Roger Federer and the Greek Stefanos Tsitsipas lost the double meeting to John Isner and Jack Sock.
From time to time it was smash mode for coach John McEnroe's team, but Roger Federer paved the way for the turn with a single win against Isner (2-0), whereupon Zverev secured his victory in his final match.
