Laver might refer to one of the following:

Rodney George "Rod" Laver MBE (born 9 August 1938) is an Australian former tennis player who holds the record for most singles titles won in history of tennis, with 200 career titles. He was the World No. 1 player for seven consecutive years, from 1964 to 1970 (from 1964 to 1967 in the professional circuit) . He is the only tennis player to have twice won the Grand Slam (all four major singles titles in the same year) – first as an amateur in 1962 and second as a professional in 1969. He is the only male player and was the first player, male or female, to have won the Grand Slam during the open era (in 1988 Steffi Graf also achieved this feat). Laver won a total of twenty major tournaments, including eleven Grand Slam tournament titles and nine Pro Slam titles. In 1967, Laver also won the Professional Grand Slam. In addition he won nine Championship Series titles (1970–75) the precursors to the current Masters 1000. Laver won and excelled on all the surfaces of his time (grass, clay and wood/parquet), and was ranked as the best professional player in the world during the five-year period he was excluded from the Grand Slam tournaments. Rod Laver is the second and last male player to win each major title twice in his career. Only Roy Emerson and Margaret Court had won all four Grand Slam tournaments twice before Laver in the history of tennis. Laver is regarded as one of the greatest tennis players of all time. Within his slams there are also 6 in doubles and 3 in mixed doubles.

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).

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.

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.
