Theo Epstein, the general manager of the Red Sox, could be on his way to the Cubs within the next few days if Boston and Chicago can finalize talks, according to sources. The Cubs have been interested in Epstein for weeks. According to a source familiar with the talks, there is still a lot to work through, but it's "possible to become true." Chicago's negotiations with Epstein about taking over the top baseball job in the organization have been going so smoothly that the team has asked Major League Baseball what protocol will be for compensation if Epstein decides to join the Cubs, according to a source. A source with knowledge of the talks said that the compensation would involve prospects and/or cash, but no major league players would be part of the deal.
