The Tennis World Cup comes back after a six-year absence and with a completely new format. The first new edition will take place from 16 to 22 July 2018 just after Wimbledon, at the Madison Square Garden in New York.
It will be an inedited format, with every tie featuring four matches: women's singles, men's singles, mixed doubles and especially mixed singles. Each match is divided into four quarters of 20 minutes each, totalling 80 minutes.
The winner of the match is the nation that has won the most games during that time period. The team who will have won more games at the end of the tie will win. They will start with three groups of four teams each. Every tie won earns a team two points, if you draw, you earn one point.
The first two teams of the group reach quarter-finals, and from that stage the knockout phase will begin. In 2018 12 countries and many top players are committed to play, including Rafael Nadal, Novak Djokovic, Alexander Zverev, Serena Williams.
However World Cup clarified through its website that the Player participation is subject to agreement and players shown are indicative only. At the moment Andy Murray features in the entry list but he is unsure about playing.
