Yes, Arizona’s position is an essential part of the whole thing.
I wonder, though, if they would play those games if the only thing that is undecided is seeding.
For example, if the Mets, win 2 of 3 this weekend, the DBacks beat the Padres 2 of 3, and the Braves get swept by KC, the Braves would be eliminated from playoff contention and the Padres would be the top WC team. Would they play at least one of the Braves-Mets games to decide the 4 and 5 seeds?
I would rather see the Brewers play the Mets than the DBacks too. Winning the series this weekend would be a step toward making that happen.
