Why is the one-game “play-in” to determine the wild card or division winner considered a regular season game and not the beginning of the playoffs? Before you brush it off as a semantic difference, consider that the Rox and Pods were able to use their extended September rosters yesterday, a huge difference in a 13–inning game. I don’t know if it was fair or unfair. But it certainly was a different game than it would have been if only playoff-eligible players were allowed.
Whatever the answer, I hope yesterday’s game set the tone for the playoffs. Fun! Discussion topic of the day: Is Trevor Hoffman a choker?
One huge reason: tiebreakers are usually played 24 hours after the end of game #162. Asking teams to create a "playoff roster" for one game on that short notice, while they're also packing their bags and trying to fly somewhere on short notice, is kinda nuts. Also, it'd lead to all sorts of anomalies like leaving off half your starting pitchers, since you won't really need them for a one-game playoff.
