Warm-ups

If you’re playing singles, you should always warm up with your opponent before your match begins.However, this is not the time to practice competitively. For the most part, you shouldn’t hit at full pace and you certainly shouldn’t try to hit winners. Place your shots around the middle of the court so your opponent can easily return the ball without having to hustle around the court.

You should stop the ball and catch it when you’re warming up your serves. Additionally, you should not hit returns unless you warn your opponent and let him know that you’d like to take a few practice service returns. You can warm up with your partner, rather than your competition, if you’re playing doubles.

Ball Management

Players should always keep a tennis ball in their hand, pocket, or ball clip during a match. You should always serve with two balls. Even the most patient tennis players dislike waiting for their opponent to find a ball to serve. If you notice that your opponent is searching for a ball, take a look around your side of the court. If you find a ball, slowly hit it so that he can easily catch it without having to run around the court.

Try to keep any extra tennis balls against the back fence. Tennis balls are a hazard if they are lying around the court. So, keep them flush against the fence so you can easily pick them up when needed.

Should your ball run onto another court, wait for an opportunity to collect it, when play has paused. Do not interrupt the players, unless they are at risk of being injured, at which point you should yell a “let” to warn them.

Keeping Score

The server should always announce the set score before the start of each game and the game score before each point. State the score loudly and in a clear voice; you do not want to recap each point at the end of the game if there is any confusion. Additionally, announcing the score lets the receiver know that you are ready to begin the next point.

Close Calls

If you cannot clearly tell whether your opponent’s shot is in or out, it’s in. You must be 100 percent sure you’re making the correct call, so the benefit of the doubt goes to your opponent if there’s any uncertainty on your part. To be safe, return all of your opponent’s shots regardless of whether it’s in play, and call the shot out in a clear voice if you know that it’s out.

You should not make calls on your own shots that land on the other side of the court. You have to respect your opponent’s decision and trust that they’re an honest player.In doubles, you should not call balls wide if you are on the far sideline and your partner is closer to the ball.Most likely, your partner has a better angle to judge whether it landed in or out, so rely on your teammate’s judgment. Similarly, let your partner make the call if you are receiving a serve and your teammate is standing near the service line. He has a better angle to see the ball, and you should trust that he will make the right call.

Behavior & Attitude

Even if you’re playing badly, refrain from shouting or looking dejected in a friendly match. Undoubtedly, your attitude effects how you play, so try to have fun and stay positive. Additionally, it’s disrespectful to your opponent to look miserable after every point. Give them credit if they are beating you, and keep your head up.Don’t talk in the middle of points. Your opponent may confuse your words and think that you are calling a shot out, so avoid unnecessary conversations. Talking is much more appropriate for a doubles team and is acceptable during a match.

Tempo

Do not deliberately slow the game down. As a rule of thumb, play at the pace of the server, which is a 10-12 second rest after the last point ended, and look ready. You’re allowed to take 25 seconds in between points, but unnecessary lagging is frowned upon.Likewise, servers should not rush to start each point, even if they prefer to play at an extremely fast pace.You should re-do the point if the server serves the ball before the receiver is ready.
