My concern with scenario 2 is if all 3 teams win tomorrow and the Mets win game 1 of the DH and both teams have clinched the playoffs would they play the second game of the doubleheader even if both teams are tied? If no then by my understanding the Mets would have the tiebreaker and be the 5 seed. They would be 6-6 against each other and the Mets have the better divisional record which the tiebreaker would defer to.
In that scenario the Braves already clinched so they don’t won’t use any of their good pitchers. They would have Sale, Fried, Lopez lined up for the WC series which honestly seems like worst case scenario to me.
