Because your legs keep moving
Unbalanced forces are important in order to move anything. An object under balanced forces does not move. For example as you sit in your chair reading this, gravity is exerting a force on your body downwards but your chair balances this force by exerting a force upwards on you that is equal and opposite to the force of gravity. These two forces oppose each other and therefore you do not move. In tennis in order to change the direction of a tennis ball you need to exert a net force(an unbalanced force) in the direction you want the tennis ball to move. In tennis there are also unbalanced torques(a force acting at a distance from a pivot point) on the ball that cause the ball to spin. Hope that helps.
