Abstract
A portable screen adapted for positionment on a softball field to protect the pitcher from fast-moving batted balls. The screen includes a rigid rectangular frame that is formed by two slidably-connected U-shaped frame elements. Two laterally-spaced foot structures are hingedly connected to lower portions of the frame for supporting the frame in an upright position. The frame and foot structures can be collapsed and folded into a small size package for placement in the trunk of an automobile when it becomes necessary to transport the screen to or from a softball field.
