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  and also the calendar year Professional Grand Slam in 1967. 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. 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. 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.

Heavy Hitter: It should not be a shock that Roger Federer’s racket of choice is one that only a true surgeon of the court can use effectively. It has both a postage stamp-sized 90 square-inch head and a 12.6oz body that will feel like swinging a hammer to the uninitiated. The reason for the added weight is basalt graphite placed in the handle. It gives experts a better feel for the ball and helps counter-weight for really deep, powerful swings meant to stick the ball in the chain-link. Using this will feel like jumping into the deep end of the pool, but if you can master it, you can use anything. Net fighters and spin doctors will both have a lot of difficulty doing battle at the net while back court clubbers will find it to be a deadly weapon. [Purchase: $159+]
Vibration dampeners (also sometimes known as "gummies") may be interlaced in the proximal part of the string array, to reduce the percussive sound of the ball hitting the strings and/or to reduce perceived vibration. They do not, however, reduce impact shock significantly, so they are of no safety value. Some professionals, such as Andrei Agassi, used rubber bands instead of specialized dampeners. Dampeners come in two main types. The first uses the two central main strings to hold it in place. The second is sometimes called a "worm" and it is woven between many of the main strings. Dampeners are nearly always placed very near the bottom of the racket string bed.
The ITF's Play and Stay campaign promotes playing on smaller courts with slower red, orange and green balls for younger children. This gives children more time and control so they can serve, rally, and score from the first lesson on courts that are sized to fit their bodies. The ITF has mandated that official competition for children under 10 years of age should be played on "Orange" courts 18 m (59 ft) long by 6.4 m (21 ft) wide. Competition for children under 8 years is played on "Red" courts that are 11 m (36 ft) long and 5.5 m (18 ft) wide. The net is always 0.8 m high in the center.
Between 1859 and 1865 Harry Gem, a solicitor and his friend Augurio Perera developed a game that combined elements of racquets and the Basque ball game pelota, which they played on Perera's croquet lawn in Birmingham, England, United Kingdom. In 1872, along with two local doctors, they founded the world's first tennis club on Avenue Road, Leamington Spa. This is where "lawn tennis" is used as a name of activity by a club for the first time. After Leamington, the second club to take up the game of lawn tennis appears to have been the Edgbaston Archery and Croquet Society, also in Birmingham.
