5. St. Louis Cardinals trade RHP Shelby Miller, OF Jon Jay and 3B Zack Cox to the Baltimore Orioles for CF Adam Jones
New Orioles GM Dan Duquette has made it clear to rebuild the Orioles he needs to start with the rotation. Miller gives the Orioles a potential front-of-the-rotation starter to go with Zach Britton, top pitching prospect Dylan Bundy and Brian Matusz (should he recover from his disastrous 2011 season). Jay can take over for Jones in center field, and Cox could become their long-term solution at third base, eventually playing next to shortstop Manny Machado, the Orioles' best position-player prospect.
The Cardinals get the pure center fielder they’ve been looking for in Jones and continue to help offset the loss of Pujols. Their starting rotation depth is good, and the farm system is loaded with arms, so giving up Miller, though painful, is the price to pay for player of Jones’ caliber. He will be a free agent following the 2013 season, so it's possible the Cards wouldn't have to part with so much quantity for his services; however, they would need to give up Miller, one of the game's top pitching prospects, and the key to this trade
