#4 Samoa Joe(c) vs. Rey Mysterio - United States Championship

NOTE: At the time of this writing, Rey Mysterio's status for the show is currently unknown due to an ankle injury he suffered on the final Raw before WrestleMania, so this match may be cancelled or Mysterio may be replaced by this Sunday.
A match between Rey Mysterio and Samoa Joe sounds like any of the matches on the old TNA versus WWE cards fans used to make, except this one has become reality.
Joe took the United States Championship from the previous owner, R-Truth, back in March and defended it against Mysterio, R-Truth and Andrade at Fastlane.
This feud should have a similar feel to AJ Styles vs. Randy Orton with two top guys from different companies finally getting a singles match on a big stage. Unfortunately, this match has not been built up and feels like another rushed match on the WrestleMania card.
Evident by the fact that this match was booked as a result of a tag team match and was announced in a backstage interview.
WWE could've done a lot better with the build to this match, but the actual match itself will be what carries this feud.
Grade: C-
