Mats Wilander (born 22 August 1964, in Växjö, Sweden) is a former world no. 1 tennis player from Sweden. From 1982 through 1988, he won seven Grand Slam singles titles (three at the French Open, three at the Australian Open, and one at the US Open), and one Grand Slam men's doubles title (at Wimbledon). He won three of the four Grand Slam singles events in 1988 and finished that year ranked World No. 1. Although he never won the singles title at Wimbledon, Wilander twice won the Australian Open when that tournament was still played on grass courts. This makes Wilander one of only five men (along with Jimmy Connors, Andre Agassi, Rafael Nadal, and Roger Federer) to have won Grand Slam singles titles on grass courts, hard courts, and clay courts. He and Rafael Nadal are the only men in tennis history to have won at least two Grand Slam singles titles on each of the three surfaces. Wilander won his fourth career Grand Slam singles title at the age of 20, the youngest man in history to have achieved that feat. In addition he also won eight Championship Series titles (1983–88) the precursors to the current Masters 1000.

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.

Horst Skoff (August 22, 1968 – June 7, 2008) was a professional tennis player from Austria.

Over the course of his career he won four top-level singles titles and two tour doubles titles. His career-high rankings were World Number 18 in singles and World Number 70 in doubles. His career prize-money totalled US$1,651,858.

Skoff played on Austria's Davis Cup team for nine years, compiling a 22-17 record. He helped the team reach the World Group semi-finals in 1990. Memorable Davis Cup rubbers which Skoff was involved in include a 6–7(5), 7–6(7), 1–6, 6–4, 9–7 win over Mats Wilander in the 1989 quarter-final; and a 6–3, 7–6(4), 4–6, 4–6, 3–6 loss to Michael Chang in the 1990 semi-final.

Skoff retired from the professional tour in 1995. He died on June 7, 2008 in Hamburg, Germany, following a heart attack. He was 39.

Darren Cahill (born 2 October 1965 in Adelaide, Australia) is a tennis coach and former professional tennis player from Australia. He was an Australian Institute of Sport scholarship holder.

Nicknamed "Killer", Cahill turned professional in 1984. He won his first tour doubles title in 1985 at Melbourne, and his first top-level singles title in 1988 at Gstaad.

Cahill's best performance at a Grand Slam event came at the 1988 US Open, where he knocked-out Boris Becker in the second round on the way to reaching the semi-finals, where he lost to eventual champion Mats Wilander.

In 1989, Cahill finished runner-up in the men's doubles at the Australian Open (partnering Mark Kratzmann).

Cahill was a member of the Australian team which reached the final of the Davis Cup in 1990. (The team lost 3–2 to the United States in the final.) Cahill compiled a 6–4 career Davis Cup record (4–0 in doubles and 2–4 in singles).

Cahill won his last tour singles title in 1991 at San Francisco. His last doubles title came in 1994 in Sydney. His career-high rankings were World No. 22 in singles and No. 10 in doubles (both achieved in 1989). Cahill retired from the professional tour in 1994 due to a knee injury.

Aaron Krickstein (born August 2, 1967), nicknamed "Marathon Man", is a former American professional tennis player, who competed on the ATP Tour from 1983 to 1996. Born in Ann Arbor, Michigan, he currently competes on the Outback Champions Series Over-30 tour.

Krickstein reached his career high ATP ranking of World No. 6, on February 26, 1990. He achieved this ranking on the back of wins in Sydney and Los Angeles, as well as his best ever results at Wimbledon and the U.S. Open.

Krickstein is Jewish, and in the mid-1990s was one of three highly ranked Jewish-American tennis players, along with Jay Berger and Brad Gilbert. His coach Nick Bollettieri remarked as to his personality when he was a teenager: "Aaron was brought up in a Jewish background and babied for 16 years. Now his father wants me to make him Italian."

His sister Kathy won the Big Ten tennis championship in 1998. He is the uncle of LPGA's golfer Morgan Pressel, who is the daughter of his sister Kathy and the youngest winner of an LPGA major.
