The Colorado Rockies should be really aggressive at the trade deadline in a couple of weeks. First off, I would call up the Tampa Bay Rays and offer them CF Dexter Fowler straight up for righty starting pitcher Jeff Niemann. The Rays are looking to deal B.J. Upton, so they will need a replacement for him and Fowler would be a good one. They should then turn their attention to the Chicago Cubs and offer them rookie 1B Ben Paulson and 2B Jonathan Herrera for infielders Jeff Baker and Blake DeWitt. Baker and DeWitt would really strengthen the bench for the Rockies. Finally, the Rockies should offer Eric Young to the Oakland A’s for outfielder Ryan Sweeney. Adding Niemann to the starting rotation and Baker, DeWitt and Sweeney to the bench would make the Rockies a very, very hard team to beat in the N.L. West.
