Philippoussis was born in Melbourne and was educated at Maribyrnong College.

Coached by his father, Nick, the right-hander has played tennis since he was six years of age. He was an Australian Institute of Sport scholarship holder. He was briefly coached by former 1987 Wimbledon champion Pat Cash, which ended in an acrimonious split in 2000. In 1994, he finished third in single ranking for juniors. Philippoussis also finished as junior doubles champion with Ben Ellwood in Australia, Wimbledon, and Italy. He turned professional in 1994.

In 1995, at the age of 19, he was the youngest player in the year-end top 50. In 1996, he reached the 4th round of the Australian Open upsetting Pete Sampras in the 3rd round and in doubles with Patrick Rafter. On 25 May 1997, he recorded a personal best 229.0 km/h (142.3 mph) serve in a game he lost to Albert Costa. During the height of his career, Mark was known as having one of the fastest serves in the game.

Peter "Pete" Sampras (/ˈsæmprəs/; born August 12, 1971) is a retired Greek–American tennis player and former world number 1. During his 15-year tour career, he won 14 Grand Slam singles titles and became recognized as one of the greatest tennis players of all time.

Sampras debuted on the professional tour in 1988 and played his last top-level tournament in 2002 when he won the US Open, defeating rival Andre Agassi in the final. He was the year-end world no. 1 for six consecutive years (1993–1998), a record for the open era. His seven Wimbledon singles championships are also an Open Era record. He spent 286 weeks at no. 1, the most of any male player. His five US Open singles titles is an Open Era record shared with former world no. 1 players Jimmy Connors and Roger Federer. Sampras is the last American male to win Wimbledon (2000) and the ATP World Tour Finals (1999).

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.

Andrew Stephen "Andy" Roddick (born August 30, 1982) is an American professional tennis player and a former World No. 1. He is currently the third highest-ranked American player, behind Mardy Fish and John Isner.

He became a Grand Slam singles champion when he won the title at the 2003 US Open, defeating Juan Carlos Ferrero in the finals, which currently makes him the last North American male player to win a grand slam singles event. Roddick has reached four other Grand Slam finals (Wimbledon in 2004, 2005 and 2009, and the US Open in 2006), losing to Roger Federer each time. He is married to Brooklyn Decker, a Sports Illustrated swimwear model and actress.

Roddick was born in Omaha, Nebraska to Jerry and Blanche Roddick. Roddick's father was a businessman and his mother was a school teacher. She now directs the Andy Roddick Foundation. Roddick has two older brothers, Lawrence and John (All-American tennis player at University of Georgia (1996–98) and head tennis coach at the University of Oklahoma), who were both promising tennis players at a young age.

Andre Kirk Agassi ( /ˈɑːndreɪ ˈæɡəsi/; born April 29, 1970) is a retired American professional tennis player and former world no. 1. Generally considered by critics and fellow players to be one of the greatest tennis players of all time, Agassi has been called the best service returner in the history of the game. Described by the BBC upon his retirement as "perhaps the biggest worldwide star in the sport's history", Agassi's performances, along with his unorthodox apparel and attitude, have seen him cited as one of the most charismatic players in the history of the game, and credited for helping revive the popularity of tennis during the 1990s.

In singles tennis, Agassi is an eight-time Grand Slam champion who competed in 15 Grand Slam finals, and an Olympic gold medalist. A multi-surface specialist, he is the first of two male players to have achieved a singles Career Golden Slam, and one of four to have achieved a singles Career Grand Slam in the Open Era (one of seven in history). He was the first male player to win all four Grand Slams on three different surfaces (hard, clay and grass), and is the last American male to win the French Open (1999) and the Australian Open (2003). Agassi also won 17 ATP Masters Series titles, the 1990 ATP Tour World Championships, and was part of a winning Davis Cup team in 1990 and 1992. He is the only male singles player in history to have won all four Grand Slam tournaments, the Olympic gold medal and the ATP Tour World Championships: a distinction dubbed as a "Career Super Slam" by Sports Illustrated.
