Differences in speeds with different balls


#1

I have to use a tennis ball because of the way my backyard is set out, if I throw my one and only baseball it will hit a solid concrete wall, any idea of how much the speed difference is between a tennis and baseball?

Thanks

A tennis ball is too light. You will not be getting the proper muscle memory nor conditioning. There are a number of “soft” practice baseballs that come in the regulation 5 ounce 9 inch weight and size available from Nike and Wilson.
