After taking a look at who the Cardinals might pursue at the trade deadline a couple weeks ago, its time to think about who the Cards might trade to get some of those players. This is not to say that any of these players will be traded in July, but that these guys are, for various reasons, potential trade chips for the team.
First Tier - The Blockbuster Guys
These guys would only be traded in a blockbuster type deal. I'm thinking along the lines of Cliff Lee, Jurickson Profar or Giancarlo Stanton.
The Cardinals top prospect is likely untouchable, but if it meant getting a player that the team could control for several years, such as Profar or Stanton, I'm sure the Cards would at least consider it. Taveras is considered the heir apparent to Carlos Beltran in the Cardinals outfield. However, the emergence of Matt Adams could make Taveras expendable.
Martinez is pitching well at AAA and could be a staple in the Cardinals rotation for years to come. However, with the abundance of young power arms in the Cards farm system, the team could decide to move him if it meant getting a guy like Lee in return. There have been questions as to whether Martinez is better suited for the rotation or pen going forward and if the Cardinals don't think he is suited for the rotation, they could make the move. They just don't want to end up making another Dan Haren for Mark Mulder type of deal.
Second Tier - The Big Deal Guys
These are guys who probably wouldn't be used in a blockbuster type deal, but could get the Cardinals a quality player in return.
Adams has proven that he is major league ready, but as he is blocked from a starting gig this year and Oscar Taveras is coming up behind him, the Cardinals could make him available for the right piece. It would have to be someone like Matt Garza, Bud Norris or possibly Ricky Nolasco.
Wong is another guy who is blocked at the major league level, which could make him expendable. As one of the Cardinals top 10 prospects, the team would like a good player in return. The Phillies could be a possibility if the Cardinals want to upgrade at short with Jimmy Rollins or perhaps Wong could be used in a bigger deal.
Bottom Tier - The Missing Piece Guys
These are guys who the Cardinals might move just to get the final piece to their playoff puzzle, such as another bullpen arm. Something along the lines of the Cards Zack Cox for Edward Mujica trade last year.
Despite posting good numbers at AAA Memphis so far this year (3.30 ERA in 54.2 innings), the Cardinals have passed on Freeman on several occasions when looking for bullpen help. At age 26, he is no longer considered a prime prospect, but he still throws in the mid-90's and could develop into a good setup man at the major league level. The Cardinals could potentially swap him for someone like lefties Wesley Wright or Oliver Perez.
Blair has fallen behind other starting pitchers in the Cardinals organization due to injury and could be trade bait as a result. He throws 92-94 mph with a potential plus curve and could garner a reliever in return, such as Steve Cishek or John Axford.
These are just a handful of the players the Cardinals might make available at the trade deadline. With the best minor league system in baseball, the Cards have an abundance of talent to draw from to get a deal done.
