Possible Realignment in Baseball?

An interesting idea for baseball is just being discussed among the movers and shakers. There is now talk of making each league 15 teams apiece instead of the National League having 16 teams and the American League having 14 teams. This move, of course, means that a NL team would have to make a move to the AL, most likely the West division considering they only have 4 teams. The team that seems ideal for the switch is the Houston Astros who are currently going through a ownership change. Of course, the concept of playoffs was brought up again along with adding a 5th team to each league. Also, there was some talk of getting rid of the separate divisions altogether.

The sticking point in all of this, though, is that this move would make each league have an uneven number of teams. Basically what would happen is that an inter league series would have to always be going on somewhere in baseball. It also means that it would become common place and not just something for a particular part of the year.

As for all this discussion, I like it. The NL Central doesn't need an extra team and the AL west could sure use one. It seems silly to keep this unevenness just because of tradition in scheduling. I know it would affect other scheduling matters but I'm sure it would be so bad. As for a 5th team for the playoffs, I still don't like the idea. That would be uneven.

P.S. I would actually rather keep divisions for the sake of regional rivalries but I would mind getting rid of them all together. The teams with the better records would then get in no matter what.
