Ilie Năstase (Romanian pronunciation: [iˈli.e nəsˈtase], born July 19, 1946, in Bucharest, Romania) is a Romanian former professional tennis player, one of the world's top players of the 1970s. Năstase was the World No. 1 tennis player between 1973 (August 23) and 1974 (June 2). He is one of the five players in history to win more than 100 ATP professional titles (57 singles and 45 in doubles). He was inducted into the International Tennis Hall of Fame in 1991. Năstase won seven Grand Slam titles: two in singles, three in men's doubles, and two in mixed doubles. He also won four Masters Grand Prix year end championship titles and seven Championship Series titles (1970–73) the precursors to the current Masters 1000. In 2005, Tennis magazine ranked him as the 28th-best player of the preceding forty years. He is the second male player to win a Grand Slam without dropping a set and the first one to achieve this feat at French Open (1973).

At the beginning of his career in 1966 Năstase travelled around the world competing with his good friend Ion Ţiriac. Together, they represented Romania in the Davis Cup competition, being three times runners up: in 1969, 1971 and 1972.

Stanley Roger "Stan" Smith (born December 14, 1946 in Pasadena, California) is a former American tennis player and two time Grand Slam singles champion who also, with his partner Bob Lutz, formed one of the most successful doubles teams of all time. Together, they won many major titles all over the world. In 1970, Smith won the first year end championship Masters Grand Prix title. Smith's two major singles titles were the 1971 US Open (over Jan Kodeš in the final), and 1972 Wimbledon (over Ilie Năstase in the final). In 1972, he was the year-ending World No. 1 singles player. In 1973, he won his second and last year end championship title at the Dallas WCT Finals. In addition, he won four Grand Prix Championship Series titles. His name is also used in a popular brand of tennis shoes. In his early years he improved his tennis game through lessons from Pancho Segura and the Pasadena Tennis Patrons.

Smith played collegiate tennis at the University of Southern California, under Coach George Toley, where he was a three-time All-American and won the 1968 NCAA singles championship and the 1967 and 1968 doubles titles. At USC, Smith was a member of Beta Theta Pi fraternity.

Guillermo Apolinario Vilas (born 17 August 1952, in Mar del Plata, Buenos Aires Province, Argentina) is a retired and former World No. 2 professional tennis player from Argentina. He was, however, thought to be the true World No. 1 in 1977 by several sources and publications, as well as through the current ATP-ranking system. Vilas was the second Latin-American to win a Grand Slam tournament.

Raised in the seaside resort of Mar del Plata, Vilas was a southpaw and played his first tour event in 1969. He was in the year-ending top ten from 1974 through 1982. He was a clay-court specialist but also played well on hard, grass, and carpet surfaces.

He won four Grand Slam titles: the 1977 French Open and the 1977 US Open (both played on clay) and the 1978 and 1979 Australian Open (both played on grass). He was also the runner-up at the French Open three times (1975, 1978, and 1982) and at the Australian Open once (January 1977).

In 1974 he won the year end Masters Grand Prix title. In addition he won five Championship Series titles (1975–80) the precursors to the current Masters 1000.

Yannick Noah (born 18 May 1960 in Sedan, Ardennes) is a former professional tennis player from France. He is best remembered for being the last French and first black man to win the French Open in 1983, and as a highly-successful captain of France's Davis Cup and Fed Cup teams. Since his retirement from the game, Noah has remained in the public eye as a very popular music performer and as the co-founder, with his mother, of a charity organization for underprivileged children. Noah is also the father of Joakim Noah of the NBA Chicago Bulls.

Noah turned professional in 1977, and won his first top-level singles title in 1978 in Manila.

Noah became France's most prominent tennis hero in 1983, becoming the first Frenchman in 37 years to win the French Open. He dropped only one set during the two-week long tournament, and defeated the defending-champion Mats Wilander in straight sets in the final, 6–2, 7–5, 7–6. Noah also became only the second black male to win a Grand Slam singles event (after Arthur Ashe). He remains the last Frenchman to have won the French Open men's singles title.

Mansour Bahrami (Persian: منصور بهرامی‎) (born April 26, 1956) is a professional tennis player. He has held dual French and Iranian nationality since 1989.

From an early age he worked as a ball boy within a sports complex in Tehran, Iran. He observed many of the best Iranian tennis players in action but he was never allowed to play. Eventually he snuck onto one of the courts but his first racquet was destroyed by an outraged armed guard who kicked him out. He resorted to learning the game through the use of his hands or frying pans or broom handles. Bahrami has often commented that his outrageous shotmaking ability resulted from mastering tennis using such unusual implements.

The time came when the Iranian team was short of players and Bahrami was finally permitted to play the game on a tennis court. His talent was obvious and he reached the Davis Cup team (and helped the team to victory at the age of just sixteen) but in the late 1970s the Islamic Revolution within Iran led to tennis being viewed as a capitalist and elitist sport. He spent the next three years playing backgammon as all tennis courts were closed down. In desperation he fled to France with his life savings, which he gambled in a casino and lost. A number of friends supported him financially as he began to play a few tournaments within France.
