Each of the openings of the meshwork being covered by a strip of material which is impervious to passage of a ball. The strip being attached at their upper end only, between the wall and the meshwork such that a ball will pass through the meshwork opening, rebound from the wall, deflect from the strips and come to rest on the ground between the meshwork and wall.
