MILWAUKEE -- As the Los Angeles Dodgers continue to wait for an official diagnosis on Hanley Ramirez's injured right side, manager Don Mattingly has started to fear the worst."Obviously it didn't sound good," Mattingly said. "When you're getting an MRI, it's usually not a good thing."The MRI exam was scheduled for Saturday evening, about two hours before game time and Mattingly figured he might not know any details until after the game.Miguel Rojas started at shortstop Saturday against the Milwaukee Brewers, and could be a fixture there for a while if the injury is as serious as Mattingly assumes.
