Tom Gullikson (born September 8, 1951, in La Crosse, Wisconsin) is a tennis coach and former professional tennis player from the United States.

During his career as a player, Tom won 16 top-level doubles titles – ten of them partnering with his now-deceased identical twin brother, Tim Gullikson. The brothers were runners-up in the men's doubles competition at Wimbledon in 1983. Tom also won the mixed doubles title at the US Open in 1984, with his teammate Manuela Maleeva.

Tom won one top-level singles title (at Newport in 1985). His career-high rankings were World No. 34 in singles and World No. 9 in doubles (both in 1984). He retired from the professional tour in 1987.

After retiring as a player, Tom became one of the original members of the United States Tennis Association Player Development Program, coaching players such as Todd Martin, Jennifer Capriati and Andy Roddick. He served as Director of Coaching for the program from 1997 to 2001.

Tom was the United States Davis Cup Captain from 1994 to 1999. He captained the teams that won the Davis Cup in 1995 and were runners-up in 1997.

John Patrick McEnroe, Jr. (born February 16, 1959) is a former world no. 1 professional tennis player from the United States. During his career, he won seven Grand Slam singles titles (three at Wimbledon and four at the US Open), nine Grand Slam men's doubles titles, and one Grand Slam mixed doubles title. McEnroe also won a record eight season ending championships, comprising five WCT Finals titles and three Masters Grand Prix titles from twelve final appearances at these two events, a record he shares with Ivan Lendl. He posted the best single season win-loss record in the Open Era in 1984 at 96.47% (82/3). In addition he won 19 Championship Series top tier events of the Grand Prix Tour that were the precursors to the current Masters 1000.

He is best remembered for his shot-making artistry and superb volleying; for his famous rivalries with Björn Borg, Jimmy Connors and Ivan Lendl; for his confrontational on-court behavior which frequently landed him in trouble with umpires and tennis authorities; and for the catchphrase "You cannot be serious!" directed toward an umpire during a match at Wimbledon in 1981. He was inducted into the International Tennis Hall of Fame in 1999, and is regarded as one of the greatest tennis players of all time.

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.
