In fastpitch softball, the Jugs machine is routinely brought in for parent/kid scrimmages at the end of practice. We have to make hitting either the machine or the bucket of balls an automatic ground rule double and stipulate that nobody is to bunt so the person feeding the machine doesn't try to make plays in front of the machine which if you do, you are likely to get burned by the wheel. The result is that the kids do try to hit it up the middle and the parent fielding that machine has to have cat like reflexes.
