Coaches Corner: The Triangle Theory
I remember once seeing a Steffi Graf practice session with her coach. The coach had marked a relatively large triangle in the middle of his side of the court. The idea was for Steffi to hit outside the triangle. Several years later when I was coaching professional players myself, I hated it when players hit short through the middle of the court because it told me that they were playing shots that resembled a “not to lose type of tennis”. Highlighting how these shots would be punished by competent opposition was something I had to address too much. I also wanted them to be able to dictate play. So, I established the triangle theory.
At the time of establishing this theory, I was coaching aggressive first strike players. Since then, I have used the triangle theory for all styles of players. For players who strike first and look to move forward and end points at net or by forcing the opponent into error, hitting the first 2 shots hard and aggressive outside the triangle after your serve or return should elicit an opportunity ball. If you are a counter-puncher or all-court player who works the points more, you may need to hit 4 or more consecutive shots outside the triangle before you earn an opportunity ball. This can vary for all players depending on variables such as the opponent, the pace, and penetration of your shots, the environment and surface, the quality of you play on a particular day and how well you are serving and returning on a particular day. On the other hand, if you hit inside the triangle, you can expect to be dictated.
I use large yellow strips to mark the triangle. The size of the triangle depends on the ability of the player I'm coaching. I usually start with the back of the triangle four racquet lengths inside the baseline and three racquet lengths inside the sidelines. I follow the rule of motor learning, which suggests players should experience success between 60-80% of the time hitting outside the triangle. If something is too difficult players can lose confidence and if it's too easy they become bored. The triangle can be adjusted as the student progresses.
A great drill that simulates a point is a two on one drill with the triangle marked on the two side. The coach feeding is on the two side behind the baseline and feeds a ball to the player on the one side. The player on the one side is aiming to hit his first two shots outside the triangle and the players on the two side can hit anywhere. If the player on the one side hits inside the triangle, the players on the two side attack his/her shot to any part of the court and they must come to net, and the point is played out. If the player on the one side hits consecutive shots outside the triangle and has earned themselves an opportunity ball, they must come to net and play the point out against the players on the two side.
Watch how the pros dictate their points by hitting outside the triangle. I use videos of pro matches to prove this to anyone in doubt. Give the triangle theory a go. It works.
