Zimmerman mostly unknown commodity – Nationals’ 3B has excelled on field but is far from household name in nation’s capital

Ryan Zimmerman walks into an Arlington, Va., restaurant on a cold December afternoon. Dressed in jeans, a checkered button-down shirt and brown loafers, the 6-foot-3 North Carolina native looks like one of the many young professionals who populate the Washington suburb. "Don't I know you from somewhere?" the host asks after greeting him, pondering Zimmerman's face for several seconds. "You look so familiar. College, maybe?" "No, I don't think so," Zimmerman says, shaking his head and shrugging his shoulders. "OK. I'll think of it," the host says as he leads the Nationals' All-Star third baseman to his table.
