Baseball is set up as 50+ series per year, that are played with little downtime.
To turn a playoff round into essentially a series doesn't differentiate the marathoners from the sprinters.
I don't think any round of the playoffs should be under 5 games.
If MLB is going to expand playoffs they should set it up more as a second season. Otherwise that first round is nothing more than just another series. Except one team hasn't played for a week & baseball's rhythms don't work that way.
