Polanco has two team options available correct? I don't think it would be a bad idea to pick up the first option and look to trade him for the right offer. As far as him being a super-sub, the only position where he is close to average defensively is second base. With the supposed availability of Lewis, Correa, Julien, Miranda, Lee and Kirilloff, there really aren't enough at bats for all the younger players.
