rush in and try to pound his weakest point -- his backhand. So the style I am famous for was not consciously planned: it was created out of the necessity of dealing with Bobby Riggs." In the mid-1950s, when Pancho Gonzales was dominating professional tennis with his serve-and-volley game, occasional brief attempts were made to partially negate the power of his serve. This, it was felt, would lead to longer rallies and more spectator interest. At least three times the rules were modified: In several important tournaments such as the United States Professional Championships the Van Alen Streamlined Scoring System (VASSS), devised by James Van Alen, was used. The match was scored as if in table tennis, with 21 points per game, 5 serves per player, and no second serves. The fans preferred the traditional scoring system, however, and in any case Gonzales continued to win under VASSS rules. Jack Kramer, by then the professional tour promoter and no longer its dominant player, also tried a three-bounce rule, in which the server could not come to the net until the ball had been in play for at least three bounces. Gonzales won anyway, and this experiment was dropped. Kramer also tried marking a secondary service line one yard behind the baseline, so that the server was further away from the net when he served. Once again Gonzales was undeterred and the original rules were restored. Other male tennis players known for their serve-and-volley technique include Pancho Segura, Frank Sedgman, Ken Rosewall, Lew Hoad, Rod Laver, Roy Emerson, John McEnroe, Stefan Edberg, Pat Cash, Boris Becker, Patrick Rafter, Pete Sampras and Tim Henman. Sampras, despite being known for his great serve and volley game, did not always come to the net behind the serve on slower courts, particularly on the second serve. This was especially the case when he was younger. Edberg is considered by many experts as the leading proponent of the serve-and-volley game in the modern era. The serve-and-volley strategy has traditionally been less common amongst female players. An early pioneer in women's volleying was Elizabeth Ryan, who was at the top of the women's game in the mid-to-late 1920s. But it was later on that serve and volley caught on in women's game. The style propelled Margaret Court to become the all-time leader in Grand Slam titles (24 in singles, 62 total). Martina Navratilova and Jana Novotná later
