Ricardo Alonso González (May 9, 1928 – July 3, 1995), generally known as Richard "Pancho" Gonzales (or as Pancho Gonzales) was an American tennis player. He was the world no. 1 professional tennis player for an unequalled eight years in the 1950s and early 1960s. He won two Major titles and fifteen Pro Slam titles.

Largely self-taught, Gonzales was a successful amateur player in the late-1940s, twice winning the United States Championships. He is still widely considered to be one of the greatest players in the history of the game. A 1999 Sports Illustrated article about the magazine's 20 "favorite athletes" of the 20th century said about Gonzales (their number 15 pick): "If earth was on the line in a tennis match, the man you want serving to save humankind would be Ricardo Alonso Gonzalez." The American tennis commentator Bud Collins echoed this in an August 2006 article for MSNBC.com: "If I had to choose someone to play for my life, it would be Pancho Gonzales."

Gonzales was given a 51-cent racquet by his mother when he was 12 years old. He received tennis analysis from his friend, Chuck Pate, but mostly taught himself to play by watching other players on the public courts at nearby Exposition Park in Los Angeles. Once he discovered tennis, he lost interest in school and began a troubled adolescence in which he was occasionally pursued by truant officers and policemen. He was befriended by Frank Poulain, the owner of the tennis shop at Exposition Park, and sometimes slept there.

Roger Federer (German pronunciation: [ˈfeːdəʁɐ]) (born 8 August 1981) is a Swiss professional tennis player who held the ATP No. 1 position for a record 237 consecutive weeks from 2 February 2004 to 18 August 2008. Federer has occupied the #1 ranking for 285 overall weeks, one week short of the record 286 weeks held by Pete Sampras. As of 28 May 2012, he is ranked World No. 3. Federer has won a men's record 16 Grand Slam singles titles. He is one of seven male players to capture the career Grand Slam and one of three (with Andre Agassi and Rafael Nadal) to do so on three different surfaces (clay, grass, and hard courts). He is the only male player in tennis history to have reached the title match of each Grand Slam tournament at least five times and also the final at each of the nine ATP Masters 1000 Tournaments. Many sports analysts, tennis critics, and former and current players consider Federer to be the greatest tennis player of all time.

Federer has appeared in an unprecedented 23 career Grand Slam tournament finals, including a men's record ten in a row, and appeared in 18 of 19 finals from the 2005 Wimbledon Championships through the 2010 Australian Open, the lone exception being the 2008 Australian Open. He holds the record of reaching the semifinals or better of 23 consecutive Grand Slam tournaments over five and a half years, from the 2004 Wimbledon Championships through the 2010 Australian Open. At the 2012 Australian Open, he reached a record 31st consecutive Grand Slam quarterfinal. During the course of his run at the 2012 French Open in Roland Garros, Federer eclipsed Jimmy Connors long standing record of 233 match wins in Grand Slam tournaments when he defeated Adrian Ungur in a second round match.

Lewis Alan ("Lew") Hoad (Glebe, New South Wales, 23 November 1934 – 3 July 1994 in Fuengirola, Spain) was a former World No. 1 tennis player.

In his 1979 autobiography, Jack Kramer, the long-time tennis promoter and great player himself, ranks Hoad as one of the 21 best players of all time. For five straight years, beginning in 1952, he was ranked in the world top 10 for amateurs, reaching the World No. 1 spot in 1956. Hoad turned professional in July 1957.

In 2012 Rod Laver, writing for Melbourne newspaper the Herald Sun, ranked Lew as the greatest player of the "Past Champions" era of Tennis. Laver described his strengths of "Power, Volleying and Explosiveness" as justification of his accolade.

Hoad won four majors as an amateur, and won the 1959 Tournament of Champions as a professional.

With his movie-star good looks, powerful physique, and outgoing personality, Hoad became a tennis icon in the 1950s. As Kramer says,

Strength played an important part of Hoad's game, as he often drove for winners rather than rallying and waiting for the right opportunity. Although he assaulted his opponents, he also had the skill to win the French Championships on the slower clay court. According to Kramer, "Hoad had the loosest game of any good kid I ever saw. There was absolutely no pattern to his game.... He was the only player I ever saw who could stand six or seven feet behind the baseline and snap the ball back hard, crosscourt. He'd try for winners off everything, off great serves, off tricky short balls, off low volleys. He hit hard overspin drives, and there was no way you could ever get him to temporise on important points."

Kenneth Robert ("Ken") Rosewall AM MBE (born 2 November 1934) is a former world top-ranking amateur and professional tennis player from Australia. He won 23 Majors including eight Grand Slam singles titles and before the Open Era a record fifteen Pro Slam titles (and completed the Pro Grand Slam in 1963). Rosewall won 9 slams in doubles with a career double grand slam. He is considered to be one of the top male tennis players of all time. He had a renowned backhand and enjoyed a long career at the highest levels from the early 1950s to the early 1970s. He was one of the two best male players for about nine years and was the World No. 1 player for a number of years in the early 1960s. He was ranked among the top 20 players, amateur or professional, every year from 1952 through 1977. Rosewall is the only player to have simultaneously held Pro Grand Slam titles on three different surfaces (1962-1963). He was the first male player during the open era to win a Grand Slam without dropping a set (1971 Australian Open).

Charlie (Charles Manuel) Pasarell, Jr. (born February 12, 1944, San Juan, Puerto Rico) is a former Puerto Rican tennis player and commentator. Representing the United States as a player, he has been heavily engaged in the administration of the professional game from the inception of the ATP in 1972 and has been Vice President when he was still playing and until recently on the Board of Directors representing the Americas tournaments.

He is also known as Charlito ("Little Charlie") because his father had the same name and was also a gifted tennis player, being the champion of Puerto Rico six times in the 1950s. The younger Pasarell won over half dozen Orange Bowl titles and five U.S. Junior titles including the U.S. Junior in Singles and Doubles (with Clark Graebner) in 1961. He attended the University of California, Los Angeles, where he won the NCAA men's singles and doubles (with Ian Crookenden of New Zealand) titles in 1966, one year after his friend and teammate Arthur Ashe. He reached #1 in the rankings of American men's players in 1967, also in 1967 he became the first man for over 30 years to win the U.S. National Indoors in successive years; this tournament was the biggest indoor tournament in the world and second only to the U.S. Championships.
