Vertices x and y dominate a tournament T if for all vertices z / = x, y, either x beats z or y beats z. Let dom(T ) be the graph on the vertices of T with edges between pairs of vertices that dominate T . We show that dom(T ) is either an odd cycle with possible pendant vertices or a forest of cater
