From ABC2 Baltimore, we get some of the reasoning behind the uni switch:
"After the Senators left Washington in 1971, the Orioles dropped all references to Baltimore on their uniforms to make the team more appealing to baseball fans in the Baltimore-Washington corridor.
"Washington has its own team now, so the Orioles are making a pronounced effort to represent Baltimore and the state of Maryland. The oriole on the cap will also get a makeover."
