There's also a big picture to all this too. Is giving up top prospects to a division rival worth a rental relief pitcher, who is not guaranteed at all to put up the same numbers as before he was traded? I don't think so. Plus if the Twins don't win the WS then we just gave up those prospects for basically nothing. There's less risk for giving up those prospects to a team in the NL or in a different division. There's good reason why intra-division trades aren't all that common.
