The Cubs and Red Sox reached an agreement that they would not hire each others employees after Theo Epstein left Boston for Chicago in Oct. 2011. That agreement remains in effect, though its exact length is not known. One published report at the time said it was three years.
How the agreement applies to Lovullo is unclear: He did not become a Red Sox employee until Oct. 2012, about a full year after Epsteins departure. In addition, teams generally allow employees to interview for promotions. For Lovullo, the Cubs job certainly would qualify.
The Red Sox, however, apparently are going by the letter of the agreement, and balking at the idea of Lovullo interviewing with the Cubs. A resolution, one source said, will come down to ownership meaning, a concession by Red Sox ownership, or perhaps some kind of special arrangement between the clubs.
