As the co-host of Felger & Mazz, the #1 sports radio show in New England with millions of listeners, Boston-based Tony Massarotti has direct dialogue with fans and potential book buyers five hours a day, five days a week. He is enormously well-connected and a huge draw for fans. And he can write. He is, of course, well-known nationally having been a go-to person on the Red Sox during their run during this time.
