A device (1) for use in ball game training comprises a panel (2) having a plurality of protrusions (7) extending from a front major surface (4). The protrusions (7) terminate in domed convex surfaces (8) of partial spherical or ellipsoidal form for deflecting a ball therefrom along a return trajectory at an angle to the panel (2) and in a direction, both of which are unpredictable for developing a player's reflexes and reaction time.
