What will the match order be at SummerSlam?

#5 Finn Balor vs. Baron Corbin

Who?

Forgettable match, forgettable contestants, forgettable layout. This is ideally suited to be a cool-down filler match after the curtain-jerker gets everyone invested in the show. If it doesn't go too long and lets people take a breather for a few minutes, it will have done the best job it can reasonably be expected to do.
