The current situation:
Looks like the Mets and DBacks will trail the Braves by one game heading into the final day of the regular season. DBacks are low-team out on tiebreakers in any scenario.
My thought is that I want either the Mets or Braves, hoping they have to play two competitive games Monday.
So, the scenario we DON'T want is for the DBacks to lose and the Mets and Braves to win. If that happens, they don't need to play on Monday. Any other result means they have to play at least one meaningful game on Monday.
The other scenario we don't want is for the DBacks and Braves to both win and the Mets to lose. That means the Mets will have to sweep a DHer to make the playoffs, in which case we'd get the Braves because that would give the Mets the 5 seed. Or, they'd fail to sweep, and we'd get the DBacks.
In other words, root for the Royals tomorrow to ensure meaningful games Monday.
Beyond that, two ways to look at it:
1) We want a three-way tie entering Monday. Three teams, two spots. This way, the Mets and Braves both HAVE to win at least one win game to both make it. A split gets them both in. Two losses, and you're out. You would think, under this scenario, Game 1 is full go for both teams. Game 2 is rest for one and full go for the other. We'd get the Mets in a split scenario, so we'd ideally want Atlanta to win game 1 and force the Mets to at least try to win the second. The risk here is either a) one team actually loses both games and we get the DBacks or b) both teams do some soft (or more overt) collusion to just get a split while maximizing rest.
2) We want the Braves to have clinched and the Mets to be even with the DBacks. This way, ATL would be resting, and the Mets would have to go all out to win at least one. Here, you probably don't get two super competitive games, but you at least guarantee that the Brewers most likely opponent has to play hard for nine innings. The downside is that, with the DH not meaning anything for the Braves, the stress on the Mets gets reduced. Or, they blow it, and we end up with the DBacks.
There are other permutations, but those are the best two for the Brewers. I think, right now, I'd lean toward scenario one. I'd like to enter Monday with the Mets only needing to win one game, but having to really go for it.
