Björn Rune Borg (Swedish pronunciation: [bjœːɳ bɔrj] ( listen); born 6 June 1956) is a former world no. 1 tennis player from Sweden. Between 1974 and 1981 he won 11 Grand Slam singles titles. He won five consecutive Wimbledon singles titles (a record shared with Roger Federer) and six French Open singles titles (a record shared with Rafael Nadal). He is considered by many to be one of the greatest tennis players of all time.

During his relatively brief pro career, Borg won 41% of the Grand Slam singles tournaments he entered (11 of 27) and 89.81% (141–16) of the Grand Slam singles matches he played. His winning rate across all surfaces (carpet, clay, hard, and grass) was 82.72% (608-127), and his winning percentage at Wimbledon was 92.73% (51–4); both are records for an entire career. He is one of four players in the open era to win both Wimbledon and the French Open in the same year and the only player to do so for three consecutive years. He is the first player to win two Grand Slams without dropping a set (a record shared with Rafael Nadal). He also won three year-end championship titles, including two Masters Grand Prix titles and one WCT Final title. In addition, he won 15 Championship Series titles (1974–1980) the precursors to the current Masters 1000.

Adriano Panatta (born 9 July 1950) is a former professional tennis player from Italy. He is best remembered for winning the French Open in 1976, and for being the only player to ever defeat Björn Borg at Roland Garros, which he did on two occasions.

Panatta was born in Rome. His father was the caretaker of the Tennis Club Parioli, and as a youngster he learned to play the game on the club's clay courts. He became a successful European junior player before turning professional.

In his early career, Panatta won top-level professional titles at Bournemouth in 1973, Florence in 1974, and at Kitzbühel and Stockholm in 1975.

The pinnacle of his career arrived in but 1976, when he won the French Open defeating Harold Solomon in the final 6–1, 6–4, 4–6, 7–6 (in the first round he had saved a match point against the Czechoslovakian Pavel Hutka). In the same year he also won the Italian Open (having saved 11 match points in his first round match against the Australian Kim Warwick) beating Guillermo Vilas in the final (2–6, 7–6, 6–2, 7–6). He finished off 1976 by helping Italy capture its first-ever Davis Cup title, winning two singles and a doubles rubber in the final against Chile. He reached his career-high singles ranking of World No. 4 that year.

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.

Vytautas Kevin Gerulaitis (July 26, 1954 – September 17, 1994) was a Lithuanian–American professional tennis player. He is known for winning the men's singles title at one of the two Australian Open tournaments held in 1977. Gerulaitis won the tournament held in December, while Roscoe Tanner won the earlier January tournament. Gerulaitis also won two Italian Open titles, in 1977 and 1979, and the prestigious WCT Finals in Dallas in 1978.

Gerulaitis led the Pittsburgh Triangles to the World Team Tennis championship title at Pittsburgh's Mellon Arena in 1975. He also won the men's doubles title at Wimbledon in 1975. He was a singles semi-finalist at Wimbledon in both 1977 and 1978. In 1977 he lost a long Wimbledon semi-final to his close friend and practice partner, Björn Borg 6–4, 3–6, 6–3, 3–6, 8–6. In 1977 Gerulaitis won the most significant title of his career at the Australian Open, when he defeated John Lloyd in the men's singles final in five sets.

In 1978 Gerulaitis won the year-end championship WCT Finals for the World Championship Tennis tour, beating Eddie Dibbs 6–3, 6–2, 6–1.

Ivan Lendl (born March 7, 1960) is a former world no. 1 professional tennis player. Originally from Czechoslovakia, he became a United States citizen in 1992. He was one of the game's most dominant players in the 1980s and remained a top competitor into the early 1990s. He is considered to be one of the greatest tennis players of all time. Lendl captured eight Grand Slam singles titles. He competed in 19 Grand Slam singles finals, record surpassed by Roger Federer in 2009. He reached at least one Grand Slam final for 11 consecutive years, a record shared with Pete Sampras, with the male primacy of 8 consecutive finals in a slam tournament (a record shared with Bill Tilden at US Open). Before the formation of the ATP Lendl reached a record 12 year-end championships (equaled by John McEnroe). He won two WCT Finals titles and five Masters Grand Prix titles, with the record of 9 consecutive finals. He also won a record 22 Championship Series titles (1980–89) the precursors to the current ATP Masters 1000. Lendl first attained the world no. 1 ranking on February 28, 1983 and bolstered his claim to the top spot when he defeated John McEnroe in the 1984 French Open final. For much of the next five years, Lendl was the top ranked player until August 1990 (with a break from September 1988 to January 1989 when Mats Wilander was at the top). He finished four years ranked as the world's top player (1985–1987 and 1989) and was ranked no. 1 for a total of 270 weeks and set a new record previously held by Jimmy Connors, since broken by Pete Sampras and Roger Federer. In 2011 he became Andy Murray's coach.
