Okay, apparently a lot of people on this forum are really against the idea of the Washington/Baltimore area having two baseball teams. The first thing I'm wondering is why they are even considered one area. They have separate media outlets (TV, newspapers, radio stations, etc.), beltways, school and business districts, and lots of other things. They also have large enough of populations to be considered separate metro areas. Here are the populations of the metro areas of Washington, Baltimore, and Pittsburgh, which is a market that contains a Major League Baseball team, an NHL, and an NFL franchise (These numbers were directly taken from the U.S. Census Bureau): Washington-Arlington-Alexandria, DC-VA-MD: 4,796,183 Baltimore-Towson, MD: 2,552,994 Pittsburgh, PA: 2,431,087 As you can tell, Pittsburgh, an area with three major pro sports franchises, is less in population than either Baltimore or DC. So if you think that the Baltimore-DC area can't support two teams, then cities like Pittsburgh, St. Louis, and Tampa shouldn't even have a franchise (I know what you're thinking, but sorry; my Cards aren't going anywhere ). Also, doesn't this area have two football teams already (the Skins and Ravens)? I think a rivalry will do great for these two franchises. The Orioles are in need of a rivalry because they never really had a true one. In their division, the Yanks and Sox have each other already, the Jays will never be one because Americans could care less for Canadian teams (sorry to the Canadian fans out there, but I'm just stating what Americans in general think), and the Rays aren't going anywhere anytime soon so a rivalry with them would just be a waste. The only real rival they have in the National League is the Phillies, but they don't play them very often and I believe the real interleague rival for the Phils is the Sox. So the Nats are the perfect fit. The two cities are within an hour of each other, there's an individual rivalry that could develop out of this (Soriano vs. Tejada), and the Nats' manager, Frank Robinson of course has an incredible history in Baltimore. I think the rivalry will be great for the area, especially a few years from now when the Nats have their new stadium. At that point, both of these teams could be playoff contenders and they could put up some really competitive and nasty battles. Not only is it great for Washington and Baltimore fans, but it's great for baseball as well.
