Mini Tennis Red is for players aged 8 and under. It is played on small courts with short rackets and soft balls. It’s just like the real game and gives players opportunities to have long rallies and play different types of shots. Our Mini Tennis Red sessions are split into the different categories based on Mini Tennis ratings and playing level. The R3/R4 sessions are for players who are beginning to serve, rally and score more competently and are interested in competing more regularly.
