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.
Balls wear out quickly in serious play and, therefore, in ATP and WTA tournaments, they are changed after every nine games with the first change occurring after only seven games, because the first set of balls is also used for the pre-match warm-up. As a courtesy to the receiver, the server will often signal to the receiver before the first serve of the game in which new balls are used as a reminder that they are using new balls. However, in ITF tournaments like Fed Cup, the balls are changed in a 9–11 style. Continuity of the balls' condition is considered part of the game, so if a re-warm-up is required after an extended break in play (usually due to rain), then the re-warm-up is done using a separate set of balls, and use of the match balls is resumed only when play resumes.

When I wrote "Tennis Court", I was looking at a lot of photography by this guy called Gregory Crewdson who, um, makes these huge, super intricate, really beautiful photographs. They kind of just, like, depict human life, and there is this an emptiness to them and there is a suburbia to them which I find really compelling. And so I was definitely thinking of that visually.
Focus on ball trajectory and how cleanly you hit the ball – this will then allow your brain to merge the technical instruction you’ve been working on with the natural way of movement that creates effortless power – and eventually sound tennis techniques will emerge that simultaneously produce a lot of effortless power and allow easy adjustments to different situations in the game.
The ATP World Tour Masters 1000 is a group of nine tournaments that form the second-highest echelon in men's tennis. Each event is held annually, and a win at one of these events is worth 1000 ranking points. When the ATP, led by Hamilton Jordan, began running the men's tour in 1990, the directors designated the top nine tournaments, outside of the Grand Slam events, as "Super 9" events. In 2000 this became the Tennis Masters Series and in 2004 the ATP Masters Series. In November at the end of the tennis year, the world's top eight players compete in the ATP World Tour Finals, a tournament with a rotating locale. It is currently held in London, England.
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.
