Dominguez is the co-author of a new tell-all book titled Baseball Cop: The Dark Side of America’s National Pastime. As the Boston Herald's Michael Silverman summarizes in an article published Tuesday:
"In the summer of 2005, Dominguez says he became suspicious about someone he claims was a member of Ortiz’ entourage known as 'Monga,' described by Dominguez as Ortiz’ 'top aide-de-camp,' who allegedly was a frequent presence in the Red Sox clubhouse. Dominguez claims to have had an informant close to Monga who witnessed Monga placing a bet on a game in Chicago between the Red Sox and White Sox on July 24, 2005. Monga, according to the book, placed a bet on the White Sox to win as well as on the 'over.'
"Dominguez alleges eventually Monga and others in Ortiz’ entourage were banned from the Sox clubhouse, a development the writer says Ortiz did not like."
Dominguez does not specifically accuse the slugger of having any role in the gambling.
"To be clear, I had no proof that Ortiz was placing bets through Monga—or had ever done so—but Monga, who was hanging around the clubhouse, was betting thousands of dollars against the Red Sox," Dominguez wrote. "At least take a look at it."
Dominguez also claims Big Papi threatened to skip the 2006 Home Run Derby if Monga and Ortiz's other friends were not allowed on the field with him. He made it through the first round by blasting 10 homers but was eliminated after hitting just three in the second round.
Major League Baseball issued a statement, via Silverman: "Major League Baseball actively cooperated with a law enforcement investigation into the illegal gambling operation that took these alleged bets. Ed Dominguez reported to his superiors at MLB that that investigation, which led to multiple arrests in 2008, did not implicate any players."
