4. Seattle Mariners:
Current 1B: Mark Trumbo, Seth Smith, Jesus Montero.
With the Mariners trading Logan Morrison to the Tampa Bay Rays, it make Mark Trumbo as the lead dog at first base. Landing someone like Chris Davis would be a significant boost. That would give them the opportunity to split Davis and Trumbo at 1B and DH. Trumbo is not the greatest defender and Davis has shown a big boost in his defense over the past few seasons.
