This all hinges on if Park can hit MLB pitching, which is entirely unproven. I said it a month ago elsewhere, but I think best case scenario for the Twins is to put Park in AAA until he's "acclimated" to US life and pitching. It could be just April, it could be longer. Don't assume he's a cleanup hitter when he's never faced an MLB pitcher and definitely don't build your lineup around him yet. If he is, then Sano or Plouffe become talking points. Until then it just means you have insurance.
