OTHER STORIES FROM TODAY'S SPECIAL PREVIEW
Below theWorld Group, the Davis Cup nations compete in zones: the Americas Zone, the Asia/Oceania Zone and the Europe/Africa Zone. In each zone, there are four groups: Group I is the highest-seeded group, and Group IV the lowest. Although they can't win the Davis Cup, they play to improve their seeding for future DavisCups.
The competition between two nations is called a tie. A tie is composed of two singles matches in which the top player from each country plays the No. 2 player from the other on Friday. One doubles match is played on Saturday and reverse singles (No. 1 vs. No. 1 and No. 2 vs. No. 2) are on Sunday.
Matches are best of five sets until the winner of the tie is settled; subsequent matches are best of three. Set tiebreakers are used except for fifth sets.
