In most professional play and some amateur competition, there is an officiating head judge or chair umpire (usually referred to as the umpire), who sits in a raised chair to one side of the court. The umpire has absolute authority to make factual determinations. The umpire may be assisted by line judges, who determine whether the ball has landed within the required part of the court and who also call foot faults. There also may be a net judge who determines whether the ball has touched the net during service. The umpire has the right to overrule a line judge or a net judge if the umpire is sure that a clear mistake has been made.
If you have played the game of tennis long enough you know that the highest wear item on your racquet by far is your grip. Not only is subject to constant wear and tear by changing hand positions and by sliding your hands into position on it, but it also rubs on the court surface on occasion and is exposed to sweat and the elements too. It’s no wonder these have to be replaced very often on a tennis racquet.
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.
But would if it’s a doubles game? How do I learn to play tennis then, you wonder?! Who serves? With doubles, the serving position rotates across teams and partners. For instance, if team partners A and B were playing doubles with team partners C and D, partner A would serve first and then it would rotate to partner C and then back to partner B and finally to partner D.
It is all based on how comfortable you are with the racket. If the racket works well with you, it is a good one. Are you hitting too many frames? Too many nets? Too many outs? Too many faults? No? then your racket is fine. Can you hit a good strong shot without the need for any strenuous effort on your part? Can you smash with the racket without your arm getting sore? Can you hit a nice serve with the right spin? If yes, you have a good racket.
Popular lawn tennis rackets vary primarily in length, weight, balance point, stiffness, beam thickness, string pattern, string density, and head size. They generally conform to unofficial standards that differ from past rackets. Currently, almost all adult rackets produced by companies such as Prince Sports, Yonex, Wilson, Babolat , Dunlop Sport, Head, Tecnifibre, and Völkl are made from a graphite composite. Those made from wood (the original racket frame row material), steel, fiberglass, aluminium are considered obsolete, although those materials are technically legal for play. Inexpensive rackets often have poor performance characteristics such as excessive flexibility and inadequate weight. No recent manufacturers use single-throated beams, although Prince tried to reintroduce the single throat design in the 1990s: the only professional who used one was Mirjana Lučić. Braided graphite rackets were considered high-end until recently and molded rackets have been the norm for some time. Molding is less expensive to manufacture and offer high stiffness. Dunlop started the transition away from aluminum based frames and popularised graphite-based racquets. Especially the Dunlop Max 200G model, once used to great effect by Steffi Graf and John McEnroe set the tone. Graphite-composite rackets are today's industry standard in professional tennis.
Another, however informal, tennis format is called Canadian doubles. This involves three players, with one person playing a doubles team. The single player gets to utilize the alleys normally reserved only for a doubles team. Conversely, the doubles team does not use the alleys when executing a shot. The scoring is the same as a regular game. This format is not sanctioned by any official body.
A grip is a way of holding the racket in order to hit shots during a match. The grip affects the angle of the racket face when it hits the ball and influences the pace, spin, and placement of the shot. Players use various grips during play, including the Continental (The "Handshake Grip"), Eastern (Can be either semi-eastern or full eastern. Usually used for backhands.), and Western (semi-western or full western, usually for forehand grips) grips. Most players change grips during a match depending on what shot they are hitting; for example, slice shots and serves call for a Continental grip.

The impetus to use some kind of a tie-breaking procedure gained force after a monumental 1969 struggle at Wimbledon between Pancho Gonzales and Charlie Pasarell. This was a 5-set match that lasted five hours and 12 minutes and took 2 days to complete. In the fifth set the 41-year-old Gonzales won all seven match points that Pasarell had against him, twice coming back from 0–40 deficits. The final score was 22–24, 1–6, 16–14, 6–3, 11–9 for Gonzales.
Sloping and drainage. Proper slope of the subgrade is critical to allow water drainage away from the court. The ground should be reasonably level, preferably on the same plane or higher than adjacent land. (The ASBA advocates a finished subgrade 4 to 6 inches above the surrounding ground.) If your site has a high water table, you may also need to install an underground drainage system. Options include French drains, properly graded gravel-filled trenches, geocomposites, and perforated drain lines surrounded with stone.
