Betting on the game is the cardinal sin of baseball, so being linked to an alleged gambler is not something ballplayers want to have happen.
Unfortunately for him, former Boston Red Sox slugger David Ortiz finds himself in such a situation.
Former Boston security agent Eddie Dominguez is one of the co-authors of Baseball Cop: The Dark Side of America’s National Pastime. In the book, it is alleged that Big Papi had a connection with a gambler (via the Boston Herald's Michael Silverman):
"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.
