Early last year I decided to add an additional team to my stable of baseball teams that I follow.
The addition of a new team into the stable is not something that is taken lightly and a variety of factors are involved in the process in order for a team to be determined worthy.
At the time of the decision to expand, my stable included the Baltimore Orioles (added in 1980), the Tampa Bay Rays (added in 1998), the Houston Astros (added in 2000), and the Washington Nationals (added in 2005). Each of the teams represented areas where I had either previously lived or had a history with following.

I still follow the Atlanta Braves and Florida (Miami) Marlins for sentimental reasons but they were considered on the outside of the core four teams.
Despite their two World Series titles, and the history of me following them since their first year in 1993, the Marlins fell from prime stable positioning a few years ago after years of inept decisions by ownership that led to repeatedly fielding a non-competitive team.
That is not to say that winning is everything, I just want to know that ownership is making an effort to field a competitive ball club year after year. Astros you have been put on notice as well.
As I mentioned, one of the criteria for selecting a team to admit into the stable is historical attachment to the team through living or traveling frequently to their home base.
