The more I read about the Upton situation, the more I believe he could be had for Bailey and Cozart/Gregorius + a minor leaguer. If the Reds can convince Arizona to take Leake instead of Bailey, this would be an amazing move.
Alternatively and much less realistically, if the Reds could somehow get Bauer included in the deal, I'd do Bailey, either SS, one of Stubbs/Heisey and any three prospects not named Hamilton or Stephenson.
