Assistant State Director

PBR Colorado strives to be the most comprehensive source of player information across the state. The Prep Baseball Report is the No. 1 resource for high school baseball in each state we cover through our variety of events, boots-on-the-ground scouting staff, daily coverage, and multimedia platforms. Our multimedia platforms and events work in tandem, ultimately creating the most powerful source of high school baseball promotion in each state.  While other organizations take a national approach, our goal is to become the authoritative voice on the ground level of each state.

We recently did a series on the top uncommitted pop-times, 60-times, arm velos, and exit velocities. Now we are doing a series on our Top 5 overall numbers for each class.
