#9 Kurt Angle vs. Baron Corbin (~10 minutes)
10 minutes is actually being generous, because it's clear that, even though this is a retirement match, Kurt Angle and Baron Corbin can't be expected to go on for long. It would get bogged down quickly. Kurt Angle isn't his old self (or he wouldn't be retiring) and Baron Corbin is Baron Corbin - not the most exciting competitor in the world.

Kurt Angle will get his emotional sendoff, but unfortunately, it won't be in a spectacular sendoff like Shawn Michaels and Ric Flair - unless John Cena shows up from out of nowhere.
#10 United States Championship: Samoa Joe (c) vs. Rey Mysterio (~8 minutes)
If any title match will get less than 10 minutes on the main card it will be this one (and another one we'll get into later).
Fortunately, Samoa Joe and Rey Mysterio don't need much time. They're good enough to do with less than 10 minutes. In that time, Joe will brutalize, Mysterio will use his high speed and agility offense, and then one of them will emerge the victor (probably Samoa Joe).
Less time would actually do this match some service.
