Matt Silverman won't run the Rays exactly the same way Andrew Friedman did for nine seasons before leaving last week for the Dodgers.After joking that he was funnier, more charming and taller than his good buddy, Silverman acknowledged that while both are "people people" and focus on communication, there are some substantive differences — one being that he plans to do less and delegate more, operating more in what he described as an "oversight role" at times."I have a different style, I have a different personality," Silverman said. "I think my lack of exact experience, and my absence of being in the role day to day for the last 10 years, gives others in the department the opportunity to do more, to add more than they otherwise might have."That starts with Chaim Bloom and Erik Neander , two bright 31-year-old assistants who were promoted Friday to vice president titles.But Silverman said their basic philosophies — focusing on run prevention by stressing pitching and defense — won't change, though he would like to see a renewed emphasis on being innovative and ahead of other teams."I think everyone in the organization on the baseball side can breathe a sigh of relief that there aren't sweeping changes, that we get to keep doing the same things we've been doing," Silverman said. "It's been successful in the past, and it should be successful in the future."Besides buying his first radar gun to scout pitchers, Silverman joked that another immediate accommodation for the new job is getting a hands-free device for his cellphone after spending about 10 hours on it his first day.
