A fabric tunnel for baseball pitching practice with a simple auto-catcher is made of netting in one embodiment. At the target end a flap with indicia of accuracy of aim also constitutes a flap that provides an audible feedback when hit and also allows the thrown balls to be captured. Straps are used to hold the tunnel in position by attachment to poles supported by guy wires or the straps could be attached to fixed objects such as a chain-link fence. |
