Exclusive from SB Nation's Amy K. Nelson. Excerpt:
The addition of another wild card team will create a play-in game between the two wild cards, but because the 2012 regular season schedule was made prior to this proposed addition, there may not be enough days built in for travel. Therefore, if MLB cannot find a resolution, the current 2-2-1 format would change to 2-3, with the division winners opening away from their respective home ballparks.
Nope, this doesn't look slapdash at all. Great job! Selig's Razor in play once again.
