I find it interesting that despite the fact that the recent realignment which awkwardly put an odd number of teams in each league practically cries out for expansion, there's been no buzz about possible expansion at all. Baseball expansion interests me. It's different from other sports. More simple, less nuanced. More than the other major sports, baseball relies heavily on local attendance and local television/radio contracts. That means more than any other sport, teams gravitate towards the areas where there are more butts to put in seats and eyeballs to put on tv screens. There isn't an MLB team in Green Bay, New Orleans, or Oklahoma City, and there won't be any time soon. It's not about getting 65,000 people there 8 weekends a year; it's about having 20,000 people there 81 times a year, often in the middle of the week. So, the cities in North America with the most butts and eyeballs: 1. Mexico City: By some counts, the largest city in the world. Yes, there's a lot of poor people. There are also a whole Hell of a lot of rich people. La Ciudad is too big, with too much money for it to not eventually have an MLB franchise. It's just a question of when Mexico can have its political and economic houses in order well enough for Baseball to make the move. Don't know if it will be in 10 years or 50, but it will eventually happen. 2. Montreal: Easily the largest US or Canadian city without a team. Like Mexico City, it's just too big not to eventually have a team. In this case, the politics and the economics aren't the impediment. It's a fanbase that feels it got hosed by the MLB, and the MLB thinking that the problem with the Expos was the French-talking hockey fans instead of the relentlessly incompetent ownership. Personally, I think a solid ownership group with a good stadium plan will make this happen. 3. Charlotte, Portland, Vancouver, Orlando, San Antonio and Sacramento: With likelihood in roughly that order. All roughly the same sized metro areas. At least one, if not both of the next expansion franchises will be in these cities. Charlotte and Portland have the edge because they're farthest from an exiting franchise. While these are all safe bets, I'm not sure why you'd volunteer to be the next Cincinnati or Pittsburgh. It's hard enough to be an expansion franchise without being an expansion franchise in the smallest market in the league. 4. San Juan, Puerto Rico and Santo Domingo, Dominican Republic: The largest Caribbean cities in the most stable countries of the Caribbean. In terms of size, these metro areas are actually larger than the previous group. They just have a bit less money. San Juan, due to its being integrated into the U.S. economy, would be the favorite. You can add Havana, Cuba to this list if the political climate between the US and Cuba ever thaws. 5. Smaller U.S. city: Las Vegas, Indianapolis, Nashville, etc. Starting to get into the area of fewer than 2 million people in a metro area. Can you actually run a baseball team when you require on average, every man, woman and child in the area to each attend a game to make a profit? Kansas City, with a good team, is struggling to get 2 million in attendance this year. Can you imagine the problems a team in a metro area half that size (Buffalo or Salt Lake City, for example) would have in getting attendance? 6. A third NYC or LA team. A second Philly or Boston team. At some point it makes more sense to put a third team in a metro area of 18 million or a second team in a metro area of 6 million than to try to get a first team in a smaller metro area. Obviously, the existing teams will have a problem with that - see the ugliness going down between the Orioles and Nationals as an example.
