WrestleMania Saturday Cody Rhodes (champion) vs. Randy Orton (with Pat McAfee) for the Undisputed WWE Championship Undisputed WWE Champion Cody Rhodes will defend his title against Randy Orton at WWE "WrestleMania 42" on Saturday.

Cody Rhodes and Randy Orton both hail from storied, Hall of Fame wrestling families who have history together as The Viper mentored a young Rhodes when he first joined WWE.
