Build the Cage
You cannot train a delivery on flat ground and expect it to hold on a mound. A portable mound puts a real slope under a pitcher in a cage or a gym, and the height should match the level they actually pitch at — six inches for most youth ball, eight for intermediate, ten for high school and up. Check the mound's footprint against your tunnel width before ordering; regulation mounds are wider than people expect.
