Stefanie Maria "Steffi" Graf (born 14 June 1969, in Mannheim, Baden-Württemberg, West Germany) is a former World No. 1 German tennis player.

In total, Graf won 22 Grand Slam singles titles, second among male and female players only to Margaret Court's 24. In 1988, she became the first and only tennis player (male or female) to achieve the Calendar Year Golden Slam by winning all four Grand Slam singles titles and the Olympic gold medal in the same calendar year.

Graf was ranked World No. 1 by the Women's Tennis Association (WTA) for a record 377 total weeks—the longest period for which any player, male or female, has held the number-one ranking since the WTA and the Association of Tennis Professionals began issuing rankings. She also holds the open era record for finishing as the year-end World No. 1 the most times, having done so on eight occasions. She won 107 singles titles, which ranks her third on the WTA's all-time list after Martina Navratilova (167 titles) and Chris Evert (154 titles).

Christine Marie "Chris" Evert (born December 21, 1954) is a former world #1 professional tennis player from the United States. She won 18 Grand Slam singles championships, including a record seven championships at the French Open and a record six championships at the U.S. Open. She was the year-ending World No. 1 singles player in 1974, 1975, 1976, 1977, 1978, 1980, and 1981.

Evert's career win–loss record in singles matches of 1,309–145 (90.05%) is the best of any professional player, man or woman, in the Open Era. On clay courts her career match win loss rate of 94.05% (316/20) remains a WTA record. In tennis writer Steve Flink's book The Greatest Tennis Matches of the Twentieth Century, he named Evert as the third best female player of the 20th century, after Steffi Graf and Martina Navratilova. Evert never lost in the first or second rounds of a Grand Slam singles tournament. She won 157 singles championships. In women's doubles, Evert won three Grand Slam titles and 29 regular tour championships.

Bettina Bunge (born 13 June 1963) is a retired German tennis player. She was born in Adliswil, Switzerland. She was part of a large group of successful German players in the 1980s, which also included Steffi Graf, Claudia Kohde-Kilsch, Sylvia Hanika, and Eva Pfaff.

With German nationality as the daughter of a German businessman, she was born in Switzerland, and resided in Peru for more than 13 years. She was a national champion in Peru at the age of 13. She later moved to Miami, Florida. She speaks three languages, German, English, and Spanish. She dealt with a series of injuries throughout her career (injuries of ear and knee, among others).

Bunge was a professional player from 1978 to 1989, appearing for the first time at number 150 in July 1978. Her highest ranking was achieved in 1983 when she reached number 6. In 1982, she registered her all-time best achievement in Grand Slam singles competition when she reached the semifinals of Wimbledon.

She won four singles tournaments, including the tournaments at the German Open, Houston, and Tokyo in 1982, and Oakland in 1983. She was finalist in Sydney in 1979, Stockholm in 1980, Houston, Tampa, Cincinnati (indoor) and Tokyo in 1981, Mahwah in 1982 and Knokke in 1987.

Susan (Sue) Barker, MBE (born 19 April 1956 in Paignton, Devon) is an English television presenter and former professional tennis player. During her tennis career, she won the women's singles title at the French Open and reached a career-high singles ranking of World No. 3. She is now one of the main sports presenters at the BBC.

Barker's tennis career began in 1973 and she won her first top-level singles title in 1974. She won three additional titles in 1975. Barker first reached the semifinals of a Grand Slam tournament in 1975 at the Australian Open. She won the German Open in 1976, beating Renáta Tomanová of Czechoslovakia in the final 6–3, 6–1, and won the French Open the same year, again defeating Tomanová in the final. In 1977 she won two singles titles, reached the semifinals at both Wimbledon and the Australian Open, and upset Martina Navratilova to reach the Virginia Slims Tour Championships final, where she lost in three sets to Chris Evert.

After an injury-plagued 1978 during which her ranking dropped to World No. 24, she won three singles titles and reached three other finals in 1979. She was named the tour's "Comeback Player of the Year" by her fellow professionals. Barker reached one final in 1980 and won the last singles title of her career at Brighton in 1981, finishing the year ranked World No. 16. She won her last doubles title in 1982 at Cincinnati, and played her last professional match in 1984.
