If the Friday/Saturday games get rained out and they can play Sunday, it would be a DH. Then you just have 1 game that I bet they stick at the end of the year, and then it most likely would not get played. I think the only way it gets played is if it affects whether or not the win the division, or the wild card. I’m actually pretty certain that unplayed games are not made up for the sole purpose of playoff seeding.
