There is an old saying - if you can bat the ball you can catch it!
Batting the ball on to a player risks the ball being intercepted. Catch it and throw the ball for control and direction.
Defenders should avoid intentionally batting the ball out of bounds, as all this does is give the play to the opposition.
Netball is about possession!
Batting or tapping the ball is lazy play and inevitably you lose possession.
Also trying to keep the ball in play by batting or throwing it wildly back into court, is not lazy play, but should definitely not be part of your game.
All this does is risk possible injury to the out of control player and the ball is usually intercepted by the opposition.
Much better to allow the opposition to take the pass giving you and your team mates time to get back into position. Regrouping if you like!
