The importance of the Davis Cup at this time cannot be overstated.
Hoad's wins at the final should be sufficient to give him the number one ranking in singles for that year.
Hoad was 5 to 0 against Rosewall that year, and 2 to 0 against Trabert.
The Davis Cup final in 1953 was played during a Royal tour of Australia, and had the character of a year-end championship, with the top four players squaring off for all the marbles.
