摘要： A device for catching a ball comprises a frame member 6 constructed on the ground or the like, a net member 7 put on the frame member 6, a mat member 1 disposed substantially at the central part of the net member 7, the mat member 1 having a strike zone 2 defined thereon, a detection means 3 for detecting the position of a pitched ball B in the strike zone 2, and a display means 4 for displaying the detected position of the ball B. When the pitched ball B collides with or passes through the strike zone 2, the detection means 4 detects the colliding or passing position and has a judgment passed on the pitched ball B as to whether it is a strike or ball in accordance with a baseball rule, and the judgment is displayed by the display means 4.Some devices for catching a ball further comprise a base member 5 permitting the total weight of the device to be arbitrarily varied with a ballast W such as water, sand, steel ball or the like, a pitch target 15 shiftable after every pitch, and/or a ball return system 9 for automatically returning the pitched ball B to the pitcher.
