Tennis 1973 Grand Prix

The circuit consisted of the four modern Grand Slam tournaments and open tournaments recognised by the ILTF. This article covers all tournaments that were part of that year's Men's Grand Prix. Bonus points were awarded to players who were nominated to play in certain 1973 Davis Cup ties and who miss tournaments through competing in those ties. The Commercial Union Assurance Masters is included in this calendar but did not count towards the Grand Prix.

On 23 August 1973 the Association of Tennis Professionals published its first list of computer rankings, using points averages rather than points totals in their calculations. These are the ATP rankings of the top twenty singles players in the first list and at the end of the 1973 season, with numbers of ranking points, points averages, numbers of tournaments played, year-end rankings in 1973, highest and lowest positions during the season and number of spots gained or lost from the first rankings to the year-end rankings.

As of 23 August 1973 Rk Name 1   Ilie Năstase (ROM) 2   Manuel Orantes (ESP) 3   Stan Smith (USA) 4   Arthur Ashe (USA) 5   Rod Laver (AUS) 6   Ken Rosewall (AUS) 7   John Newcombe (AUS) 8   Adriano Panatta (ITA) 9   Tom Okker (NED) 10   Jimmy Connors (USA) 11   Jan Kodeš (TCH) 12   Paolo Bertolucci (ITA) 13   Roger Taylor (GBR) 14   Marty Riessen (USA) 15   Tom Gorman (USA) 16   Nikola Pilić (YUG) 17   Cliff Richey (USA) 18   Mark Cox (GBR) 19   Roy Emerson (AUS) 20   Karl Meiler (FRG)
