My 2018 will be attending his first college HS prospect camp over winter break. It's at a local small D1. We're doing it mainly for the experience so he knows what to expect at bigger camps. He is attending as a pitcher and the camp includes two bullpen sessions. We aren't really sure what he will be asked to do during the bullpen sessions. Can anybody provide some insight into how these are typically run? We're just trying to prepare him. Thanks!
