From Papi: My Story, by David Ortiz with Michael Holley (to be published May 16, 2017):
Everyone I knew was unimpressed with Valentine, the new manager of the Red Sox. He was hired in late November 2011, and the negative reaction from my baseball friends was instant. There were the sarcastic "good luck" messages. There were ominous warnings to get ready. Some even suggested that, at 36 years old, I probably wanted to retire rather than play for someone like him. ...
I did some research and learned that there was basically one person in the organization, team president Larry Lucchino, who really wanted to hire Valentine.
