When shopping for a tennis racquet, decide whether you are looking for a pre-strung racquet or an unstrung racquet. Pre-strung tennis racquets are a good choice for most beginner and intermediate players, as they are highly versatile and allow you to focus on the fundamentals without added complexity. Advanced players often prefer an unstrung racquet, which allows them to tailor the string type and tension to their swing and playing style.
Frame shows use seen as some scuffing/paint wear to the sides/edges as well as some play wear to the bumper guard, otherwise a solid racquet just needing some strings for play. (No cracks to the frame) See pics! Can zoom in for detail. The white grip shows some dark marks but is in good playable condition. (4 1/8") Returnable only if in unused original listing condition as pictured.
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.
The rules of modern tennis have changed little since the 1890s. Two exceptions are that from 1908 to 1961 the server had to keep one foot on the ground at all times, and the adoption of the tiebreak in the 1970s. A recent addition to professional tennis has been the adoption of electronic review technology coupled with a point-challenge system, which allows a player to contest the line call of a point, a system known as Hawk-Eye.
