Boston Red Sox executive Theo Epstein has agreed to a five-year contract with the Chicago Cubs, according to multiple media reports.

The 37-year-old Epstein would leave the Red Sox with a year remaining on his contract as general manager and take over what is expected to be an expanded role with the Cubs, who have gone 103 years without a World Series championship.

Radio station WEEI in Boston, ESPN the Magazine and SI.com all cited unidentified sources in reporting that Epstein has agreed to a deal. Details, which could include compensation to the Red Sox, were still being worked out. The Cubs declined comment Wednesday and Red Sox officials could not be reached. (AP)
