First off in the scenario you're describing it makes no sense to assume a constant voltage, so you shouldn't be conflating amps and watts.
Second, the amount of watts going through a wire is not at all the same as the amount of watts being dissipated/expended in a wire. You're assuming that it's being used as a space heater, and it's not. The baseball is going through a very thin or empty environment and 99+% of the energy is still there at the other end.
