I was talking about the Twins. They have 2 veterans to trade, plus Polanco, plus prospects (unless you are trading Sano or Buxton) to get starter(s). Sure, if you have veterans you can trade for AA or AAA players. That involves risk, though, as you are now trading for a player in the 30s - 50s or so, most likely. While they don't usually fully bust, they do carry risk. AKA, Meyer, May, Worley....
