On To The Next One: Carlos Guillen

As of the publishing of this post, the official website for Peter E. Greenberg and Associates still lists Carlos Guillen as a client.  But according to, Guillen left Peter Greenberg for Octagon earlier this Spring.  In October 2010, Greenberg also lost Rafael Soriano to Scott Boras.

Carlos Guillen will be on the disabled list at the start of the 2011 season due to microfracture surgery performed on his knee.  He has not played in any Spring Training games to date.  Once he returns, though, Guillen should go back to being the Detroit Tigers’ regular second baseman.
