# 1978 Davis Cup Americas Zone

The Americas Zone was one of the three regional zones of the 1978 Davis Cup.
10 teams entered the Americas Zone in total, with 3 teams entering the North & Central America Zone and 8 teams entering the South America Zone. The winner of each sub-zone advanced to the Americas Inter-Zonal Final, with the winner going on to compete in the Inter-Zonal Zone against the winners of the Eastern Zone and Europe Zone.
The United States defeated South Africa in the North & Central America Zone final, and Chile defeated Argentina in the South America Zone final. In the Americas Inter-Zonal Final the United States defeated Chile and progressed to the Inter-Zonal Zone.
The North & Central America Zone was marked by a number of incidents related to the continued presence of South Africa team. Canada, Mexico, Venezuela, and the Caribbean/West Indies teams all withdrew from the competition, and large scale protests accompanied the final between the United States and South Africa at Vanderbilt University in Nashville, Tennessee. In an effort to appease its critics, South Africa named Peter Lamb as one of the six members of its team, as its first-ever "coloured" player. However, Lamb did not play, and his inclusion in the squad was derided as tokenism. Crowds of up to 5000 turned out in protest.
