Baseball Cop is the story of Eddie Dominguez, a decorated member of the Boston Police Department who worked for Major League Baseball first as a Resident Security Agent for the Boston Red Sox and then as an officer for the league's newly founded Department of Investigations (DOI).

In the DOI, Dominguez had a unique view into the dark side of America's pastime, examining scandals involving drug use, age and ID fraud, human trafficking, and cover-ups. Now he is prepared to share the secrets that came across his desk every day for six years.

As MLB disbanded DOI, it tried to control any information its investigators may have collected during their service. But Eddie Dominguez refused to fall in line and sign the Non-Disclosure Agreement given to the other DOI members who were terminated. As a result, every recollection in this book is thus his to freely tell, and can be substantiated by others.

Baseball Cop will be written in alternating first-and-third-person chapters with Teri Thompson and Christian Red, co-authors of American Icon: The Fall of Roger Clemens and the Rise of Steroids in America's Pastime (Knopf: 2008).
