Retrieves baseballs during practice! The four "fang" design grips the baseball and holds on for easy pick-up. Fits on the end of any 2 1/4" bat, and is ideal on the end of your wood fungo bat. Balls release easily with a tap on the side of a ball bucket or pulling slightly with your free hand. Saves time and energy, greatly reduces fatigue from endless bending over and reaching down to pick up balls. Can also double as a bat stand. Sturdy plastic construction holds up to repeated use. Developed in conjunction with Bill Nye "The Science Guy".
