Safin won two grand slams and reached the World No. 1 ranking during his career. He was also famous for his emotional outbursts and sometimes fiery temper on court. Safin also holds the record for most broken racquets in a year with 87. Safin is the older brother of former World No. 1 WTA player Dinara Safina (Dinara Mikhailovna Safina) (Russian: Динара Михайловна Сафина), born April 27, 1986 in Moscow. They are the first brother-sister tandem in tennis history to both achieve No. 1 rankings.

Safin began his professional career in 1997, and held the No. 1 world ranking for a total of 9 weeks between November 2000 and April 2001. He won his first Grand Slam title at the 2000 U.S. Open after defeating Pete Sampras, and won the 2005 Australian Open, defeating Australian Lleyton Hewitt in the final. Safin helped lead Russia to Davis Cup victories in 2002 and 2006. Despite his dislike of grass courts, he became the first Russian man to reach the semi-finals of Wimbledon at the 2008 Wimbledon Championships. At the time of his final Grand Slam appearance at the US Open on September 2, 2009, Safin was No. 58 in the official world men's tennis rankings.

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.

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).

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.

Lleyton Glynn Hewitt ( /ˈleɪtən ˈhjuːɨt/; born 24 February 1981) is an Australian professional tennis player and former world no. 1, who has a current ATP ranking of 176.

Hewitt is the youngest male ever to be ranked no. 1 at the age of 20. His career achievements include winning the 2000 US Open men's doubles, the 2001 US Open and 2002 Wimbledon men's singles, and back-to-back Tennis Masters Cup titles (2001 and 2002). In 2005, TENNIS Magazine put Hewitt in 34th place on its list of the 40 greatest tennis players since 1965.

Hewitt might well have followed in the footsteps of his Australian rules football-playing father Glynn. Instead, he became one of the youngest winners of an Association of Tennis Professionals (ATP) tournament when, as an almost unknown youngster, he won the 1998 Next Generation Adelaide International, defeating Andre Agassi in the semifinals. Only Aaron Krickstein winning Tel Aviv in 1983 and Michael Chang winning San Francisco in 1988 were younger when claiming their first ATP title. Hewitt then left Immanuel College to concentrate on his tennis career.. He was an Australian Institute of Sport scholarship holder.
