There are negotiations being made that are going to answer all of your questions and solve all of your problems. MLB Realignment

HIGH AND TIGHT

There is a proposal out there for to "realign" Major League Baseball in the following manner:

1. Move 1 National League team, presumably the Astros, to the American League, and even the leagues at 15 teams each
2. Balance the schedule in some way
3. Have the top 5 teams in each league qualify for the playoffs

Welcome to the NHL.
 
/facepalm

This idea is said to have a 50/50 chance of coming about, and is the single most stupid idea I have ever heard. This is a very high bar in a sport that uses its All-Star Game to determine home field in the World Series, merely because Joe Torre ran his pitching staff like a charity softball game.

Other "fringe benefits":

- With an odd number of teams in each league, the necessity for an Interleague game every day.
- Scheduling balance that will require 84 games in your own league and 78 games versus the other league.
- Some resolution of the DH -- likely its adoption in both leagues -- since in this scenario nearly 25% of the schedule would be played under a different set of rules. This would almost require a taxi squad.
- A scheduling nightmare.
- A systemic change to over 100 years of established league rivalries. It would kill the fabric of baseball as we know it.
- The likelihood that some contender will finish a season against a weak team from the other league.
- Pennant races would be reduced to a riveting contest for 5th place.
- Obsolescence of all AL and NL records.

This could only happen in Seligworld.
