Does anyone know how the MLB draft works? What happens if a team drafts a player and then he decides to go the college? For example, the Yankees drafted Andy Pettitte's son Josh but Andy says he's more than likely going to be going to Baylor. Also, the Yankees originally drafted Gerrit Cole but he wound up attending UCLA and was then drafted by the Pittsburgh Pirates (he'll be making his debut Tuesday against the Giants). So what happens if a team drafts a player and he decides to attend college instead?
