From What I can tell.....
If Braves win, DBags lose, Mets lose, We are in. We play Double header on Monday with Mets needing to win 1 to get in and both to jump us in the seeding.
If Braves win, DBags win, Mets lose, We are in. We play Double header with Mets needing to win both games to get in which would also jump us in the seeding.
If Braves win, DBags lose, Mets win, We are in, Mets are in. We play double header Monday needing 1 win for higher seed and Mets needing both games to higher seed.
If Braves lose, DBags win, Mets lose, We need to win 1 game of DH to get in and Mets need to win both to get in but would also get higher seed
If Braves lose, DBags lose, Mets win, Braves and Mets both need 1 game to win to get in. Mets still need to win both to get higher seed
If Braves lose, DBags win, Mets win, Braves and Mets both need 1 game to win to get in. Mets still need both for higher seed.
I think that covers every scenario
If Braves lose, DBags lose, Mets lose, We are in, Mets need to win 1 to get in and 2 of DH to get higher seed.
