This is the last stage of development before moving on to yellow ball. It is an important progression as it allows a player to further hone their technique and skills before applying these to a more challenging yellow ball situation. The players now play on a full size tennis court with the only difference being that a green ball bounces lower than a yellow one.

This is the level where there is an increased focus on tactics and match play, as the players must see how the techniques they have learnt can be applied to win points and matches.
