Since one purpose of the Midwest League is to sort out the prospects, identifying prospects can become an obsession. It's certainly a common question in my E-mail.
Many folks sort minor league players into two categories.
This view of the world has some value, but it's not a good lens for watching the contest on the field because it devalues the everyday game. Nearly every player who takes the field in the Midwest League has the physical ability to play big-league baseball. That's one reason they're here. The best players in this league are hardly finished products. They're playing as much to learn as to win, and our league provides a daily education.
