Perhaps one of the most famous and best known tennis coaches wrote an article entitled, “Go for Every Ball No Matter Where it Lands”. He quoted the advice that Richard Williams, father of tennis greats, Venus and Serena, had imparted to them at an early age.
As a sports psychologist I am trained to look at advice in a systematic way: What works best for which person in which situation, under what circumstances?
The benefits of going for every ball even the ones that are very far out is that you may actually get some of them that both you and your opponent felt were impossible. It can build your confidence, speed, anticipation etc. It also sends a message to your opponent that they can’t let up or assume they have hit a winner. By going for everything, you may put pressure on some opponents to try and hit better shots which may result in them making more mistakes.
The risks of going for every ball, even the ones that are clearly way out of reach and those that are far out of the court are that you may get injured by being over stretched or hitting a ball from a very awkward position. You may also tire yourself out, especially if it is a hot day and/or you a playing a long match or matches. In these cases, you are likely to make any number of “fatigue” errors that outweigh the benefits of running down EVERY ball.
A smart player needs to balance risk/reward in running for shots and learn how to play efficiently. For example, if you are ahead 5-0, 40 love, NOT risking running into a fence to retrieve a great top spin lob your opponent just hit over your head might be a good mental strategy at that time!
The take away is, “no one size fits all”. Think of advice in a “general “ way and apply it to your needs and situation.
