Five days after the World Series ends, free agents will be free to sign with any team. Our current list is here, but often a few key names are plucked off the market early by signing an extension or new contract with their team. For example, in October 2011, the Yankees were able to negotiate an extension with C.C. Sabathia prior to him opting out and reaching the open market. Such deals could even happen now, like when the Astros added two years for Brett Myers in August 2010. Below we've identified six players teams may want to retain before they hit the open market. Let us know which will get a deal done! You can choose multiple players. You can view the poll results here.
