Attorney, Agent or FirmInternational ClassesA63B 63/00 (20060101)A63B 69/00 (20060101) AbstractA pitching practice device consisting of a sheet of canvas or the like supported in a vertical plane, and having an aperture formed therein defining a strike zone, at which a baseball pitcher may pitch baseballs to develop his accuracy and control. For still greater accuracy of control, and to "catch" the balls, a canvas chute is attached to the rearward surface of the sheet, and divided into a plurality of sections each opening through the sheet aperture, for receiving and trapping any ball entering its opening. The sheet aperture is thus divided into zones for indicating, and recording, whether a pitched ball is "high", "low", "inside", "outside", or "down the middle". The sheet is resiliently supported to prevent damage either to the device or to the ball. The device may also be adapted for use, with a set of playing rules, as a competitive game, particularly for children. | |
