The text of Theo Epstein's exit statement is at MLB.com.

My decision not to return as General Manager of the Red Sox is an extremely difficult one. I will always cherish the relationships I developed here and am proud to have worked side-by-side with so many great people, in and out of uniform, as together we brought a World Championship to Boston.

In my time as General Manager, I gave my entire heart and soul to the organization. During the process leading up to today's decision, I came to the conclusion that I can no longer do so. In the end, my choice is the right one not only for me but for the Red Sox.
