Great five-tool players aren't born that way. And great five-tool players aren't just the products of hard work. To be a true five-tool player, you have to be lucky enough to have been blessed with exceptional athletic ability. Then you have to marry that ability with the hard work and discipline needed to allow those tools to develop into skills. All of that takes lots of at-bats and physical maturity to bring together. And when you take a trip to the Rookie-level Appalachian League, you can watch the next generation of five-tool talents in their incubators.
