There is, technically, such a thing as a pitching prospect; the presence of pitchers on draft boards and top-100 lists suggests as much. As the profile of the major-league pitcher evolves, however, so does the criteria by which minor leaguers and amateur talent have to be assessed. Should evaluators employ a “minimum acceptable velocity”? How ought the chance of injury be integrated into a Future Value grade? Guest Eric Longenhagen answers questions very similar to these, if not these questions exactly.
