Bullpen Book allows a coach or parent to track practice bullpen sessions of multiple pitchers. In version 1.0 there are three report pages for viewing the data of a bullpen session: Performance Report, Velocity Report, and Location Report. This version comes with the most common pitch types loaded, but additional pitch types can be added. The application can help coaches see if a pitcher is getting good separation between fastballs and off-speed pitches and track a pitchers progress over time. Special thanks to HITS Athletic Training in Athens, AL for helping me test the software at their excellent indoor facilities.
