i think this is the simplest way to do things. trevor bauer was rumored to have almost been called up for the diamondbacks in september, because he was destroying the low minors and they thought maybe he could help as a bullpen arm. it didn't happen, but to me it's silly to allow whoever's nearest to the computer when they find out that trevor bauer has been called up on september 5th to claim him and keep him, or for him to be exposed to the mlb draft the following year. if there are japanese or cuban players who come over and are clearly major league ready, i'm fine with them going into the major league draft the following year, but i think the rule should be that all rule 4 draftees or young international signees since the previous year's draft should be in the minor league (prospect) draft only.
