Davis Cup structure

Sponsorship the way you would do it
The Davis Cup tennis competition is structured around a number of groups, with promotion and relegation between them.

At the top is the World Group, which competes in a knockout competition. Below that it becomes regional, with an American Zone, Euro/African Zone and Asia/Oceania Zone. Each of these zones contains four groups. The upper two groups play a knock out competition, while the lower two groups play a round robin competition. The winner(s) of each group are promoted to the one above, while the losers are relegated to the one below. There are two exceptions: Group Four countries are not relegated (as there is no where for them to go) and Group One winners play-off against losers of the World Group first round to decide who will be in the World Group next year.
