A tennis match is intended to be continuous.[65] Because stamina is a relevant factor, arbitrary delays are not permitted. In most cases, service is required to occur no more than 20 seconds after the end of the previous point.[65] This is increased to 90 seconds when the players change ends (after every odd-numbered game), and a 2-minute break is permitted between sets.[65] Other than this, breaks are permitted only when forced by events beyond the players' control, such as rain, damaged footwear, damaged racket, or the need to retrieve an errant ball. Should a player be determined to be stalling repeatedly, the chair umpire may initially give a warning followed by subsequent penalties of "point", "game", and default of the match for the player who is consistently taking longer than the allowed time limit.[66]

Before and during the open era, Rod Laver remains the only male player in history to have won the calendar year Grand Slam twice in 1962 and 1969 [101] and also the calendar year Professional Grand Slam in 1967.[102] More recently Björn Borg and Pete Sampras were regarded by many of their contemporaries as among the greatest ever. Andre Agassi, the first of two male players in history to have achieved a Career Golden Slam in singles tennis (followed by Rafael Nadal), has been called the best service returner in the history of the game.[103][104][105][106] He is the first man to win grand slams on all modern surfaces (previous holders of all grand slam tournaments played in an era of grass and clay only), and is regarded by a number of critics and fellow players to be among the greatest players of all time.[103][107][108] However it must be noted that both Rod Laver and Ken Rosewall also won major Pro Slam tournaments on all three surfaces (grass, clay, wood) Rosewall in 1963 and Laver in 1967.[109]
"Tennis Court" debuted atop the New Zealand Singles Chart dated 17 June 2013, becoming Lorde's second number-one single on the chart following "Royals", which reached the top position in March 2013.[55][56] It spent 21 weeks on the chart, six of which in the top ten.[56] The single received double platinum certification from Recorded Music NZ for exceeding sales of 30,000 copies in the country.[57] "Tennis Court" was the 19th best-selling single of 2013 in New Zealand.[58] In neighbouring Australia, the single peaked at number 20 on the ARIA Singles Chart and remained on the chart for 22 weeks.[59] It was certified triple platinum by the Australian Recording Industry Association for shipments of 210,000 units.[60]
Grass courts are the fastest type of courts in common use.[7] They consist of grass grown on very hard-packed soil, which adds additional variables: bounces depend on how healthy the grass is, how recently it has been mowed, and the wear and tear of recent play. Points are usually very quick where fast, low bounces keep rallies short, and the serve plays a more important role than on other surfaces. Grass courts tend to favour serve-and-volley tennis players.
Tennis is played by millions of recreational players and is also a popular worldwide spectator sport. The four Grand Slam tournaments (also referred to as the Majors) are especially popular: the Australian Open played on hard courts, the French Open played on red clay courts, Wimbledon played on grass courts, and the US Open also played on hard courts.
