#6 United States Championship: Andrade (c.) vs. Angel Garza vs. Humberto Carrillo vs. Rey Mysterio

Andrade and Humberto Carrillo started a feud with each other in December. Rey Mysterio got involved in the rivalry and Andrade eventually managed to take the United States Championship from him at a live event in Madison Square Garden.
Andrade and Humberto Carrillo had multiple matches with each other over the United States Championship. Angel Garza then made his Monday Night Raw debut from NXT and 205 Live after Andrade got suspended.

All four luchadors have had a number of matches with each other and it would only make sense for this to lead to a WrestleMania match between the four. They have all traded victories over each other and each challenger has a logical reason to be allowed to challenge for the United States Championship.
There has been a series of spots on the concrete in this rivalry that will likely lead to some sort of insane spot at WrestleMania.
Winner: Angel Garza
