If he continues to play baseball, they still have the exclusive rights they paid for. If he met the terms of the contract, he owes the Twins nothing morally. If he stays and makes the team and wins a Cy Young as a rookie this year, with the Twins pay him like the best pitcher in baseball next year, or will they pay him like a 2nd-year player who has almost no leverage? I suppose they might sign him to a long-term contract with some money in exchange for more years of control, but we don't call the pre-arb players "serfs" for nothing. Right now he's at the less-than-serf stage. If he decides this isn't working and he wants to get on with his life, he is free to do so, free of charge. Edit - I know my post may be piling on, but I think you're far enough of base on this to add to the pile. Normally I either agree with you or at least can see your side, but I'm missing it this time.
