Securing the ball must start in the way you practice so that ball security is something you do naturally without having to think about it. Anytime you touch the ball, even just warming up, make sure you tuck it away and secure the ball.

 

Cover the front tip of the ball with the palm and fingers of your hand, pull the ball close to your body with your forearm, push the back point in the angle of your elbow and squeeze it tight.

 

Anticipating and expecting the hit and the corresponding automatic motion of securing and protecting the ball should help you keep the ball in your hands.
