Plan of Attack for Getting the Most out of Tennis Ball Machines

Originally written by Joe Dinoffer for Ace Attack – January 2016

There are thousands of tennis ball machines in the United States alone, but how many players enjoy ALL the potential benefits of ball machine use? Sure, there is some benefit to hitting ball after ball after ball, but why not make the most out of your ball machine practice? 

Here are the six keys to good ball machine practice:

  1. Use a remote or practice with a partner
  2. Do not hit more than 10-12 in a row
  3. Pause for 15-20 seconds in between each sequence
  4. Move into position for every shot
  5. Time the machine to the ball you are hitting
  6. Set up realistic targets


Have you ever seen someone hitting on a ball machine, gone away for 10 minutes, and then come back to see them in the same position and still hitting? No offense to those who enjoy the risk of repetitive stress, but this can be an innocent mistake. We see people hitting 50-100 balls in a row on a machine without pausing and assume they are getting a great practice. 

After all, they get in more ball strikes and exercise in less time, right? The question here is whether you are looking for quality or quantity. Considering that the average tennis point may only last three ball strikes, and a very long point might be 20 strikes, how to use ball machines as an effective practice tool is an important issue. For example, a 20-hit rally means each player strikes the ball ten times. Then there is up to a 20-second pause in between points.    

Key #1 Use a remote or practice with a partner

Most ball machine users hit too many balls in a row without pause because few players enjoy picking up a court full of balls. Using a ball machine with a remote control allows players to pause and restart the action at any time easily. Without a remote, players avoid pausing because they have to run to the other side of the net just to pause the machine. 

And, while heading to the other side, the machine will keep firing balls, creating more of a cluster of balls to pick up! Another idea is to find a partner to share your time on the machine. With a partner, one player hits while the other picks up balls, and then they switch. But still, carefully consider and limit how many balls in a row each person hits.

Key #2 Do not hit more than 10-12 in a row

The primary reason to limit how many balls are hit in a row is to help you establish a standard for quality that you can consistently maintain. The number of balls hit should push your threshold of shot tolerance and focus but still be realistic. I would also recommend changing the number of balls hit in your ball machine patterns. 

Suppose you have a remote or partner who will turn the machine on and off, practice 2-ball patterns, 3-ball patterns, 4-ball patterns, etc. The idea is to practice in as play-realistic a situation as possible. Another mistake that recreational players make is stopping when they make a mistake instead of finishing their pattern. For example, if you are working on a 6-ball pattern on your forehand side, trying to hit five balls crosscourt and finish with a 6th ball down-the-line, finish the entire 6-ball sequence instead of stopping if you happen to miss shot #4. 

This approach will help you mentally in several ways. It will help you to not dwell on mistakes, to make quick adjustments to errors, and to stay focused in the face of adversity. 

Key #3 Pause for 15-20 seconds in between each sequence

There’s a sport called “Speed Golf,” which pushes players to jog or sprint from shot to shot. But, there is no such thing as Speed Tennis. The rules are clear, and it is helpful on many levels to manage time well in a tennis match, not just on changeovers but also in between points. How does this apply to ball machine practice? Let’s say you are practicing a 4-ball pattern and set the machine to fire balls to the middle of your backhand court. The first three are hit with your backhand crosscourt. The 4th is hit more aggressively with an inside-in forehand attempt to finish the point and hit a winner. You should pause the machine, go through your between-point ritual, and then play the next sequence of 4 shots as if it were the next point in a match.  

Key #4 Move into position for every shot

Many people practice on a ball machine, and it looks like they think the ball is a dog. Standing in one place and waiting for the ball to come to where you are standing is a major practicing pitfall. You can train a dog to come to you when called. A tennis ball cannot be trained. The point here is to be sure to recover to the same place on a court that you would in a real match. Standing to one side and waiting for the ball to come from a machine is simply not realistic and, comparatively speaking, will not help you improve your match results nearly as much as recovering after each shot as if you are actually playing a real point.  

Key #5 Time the machine to the ball you are hitting

With what frequency should you set the ball machine to feed balls? This is not ball speed but ball frequency, or how much time lapses between feeds. 

The answer is that it all depends on the speed of the balls you are hitting. To create a realistic practice environment, you need to pretend the ball machine is your opponent or hitting partner. Set the machine to throw the balls at the same frequency you are hitting based on your average ball speed. 

Simply put, set the ball machine to fire balls to coincide when your ball crosses the ball machine, which presumably will be a couple of feet behind the baseline on the opposite side of the court from where you are standing. If you have it set at too slow a frequency, you will be practicing to be slow in recovery, ball recognition, and preparing to hit your shot.

Key #6 Set up realistic targets

Over several decades of coaching, I have asked dozens and dozens of players hitting on ball machines or performing groundstroke drills where they aim. 

More often than not, they will give you a very non-specific answer, such as crosscourt. But the fact is that knowing where you are aiming is critical to improving in tennis. One person’s idea of crosscourt may be within 6 inches of the sideline, and another player may visualize their crosscourt target as 6 feet inside the baseline and 6 feet inside the sideline. What is a realistic target? 

First, it should not be too close to either the baseline or sidelines to allow for a good margin for error. Two or three feet from any boundary line is a good starting point. 

Next is to make the target big enough for the player to successfully hit into that target zone about 70% of the time. The weaker the player, the larger the target area and vice versa. And, when you set up targets, do not be lazy and just set out a few empty ball cans or a small hand towel or single cone and expect the player to hit it consistently. 

Confidence is a big part of winning at tennis. And to become more confident, players must consistently succeed at their drills and exercises so they can duplicate them at the time of contact.
