#7 Triple H vs. Batista
What better way to calm the crowd than the latest 20 minute Triple H entrance?
In all seriousness, this match is a good candidate to let fans cool off, take whatever mental breaks they need to, while being interesting enough to maintain engagement. Triple H's WrestleMania matches are usually slow-paced, but the career stipulation is sufficient to add some intrigue as the crowd prepares to enter the second half of the show.
#8 AJ Styles vs. Randy Orton
There's not much story behind this match, but it's a first time ever match. Randy Orton's character is still at its best. AJ Styles is AJ Styles. This will be a good mix of character and ring work to re-engage the audience with a blistering wrestling match and brawl all at once.
If anyone can motivate Randy Orton to deliver a great match, it will be AJ Styles. This will be a great way to end the first half of the long show and begin the second half, in effect, starting the show all over again as another sort of curtain-jerker.
