Not in many years has the Australian Davis Cup picture been so confused. During the dozen years it has dominated Davis Cup play, Australia has always had at least a brace of outstanding players. It began with Sedgman and McGregor and moved on with Hoad and Rosewall, Cooper and Anderson and, finally, Fraser, Laver and Emerson. Now it is the U.S., with Ralston and McKinley, that has the strong pair. When the Davis Cup is placed on the courtside table this year, Australians had better take a good look at it. It may be some time before they see it again.
