#6 Aleister Black vs. Randy Orton

For weeks, Aleister Black has been delivering promos on SmackDown Live in which he asks for someone to pick a fight with him. Until recently, no one would accept his challenge and knock on his door.
This was until last week when at the end of Aleister Black's promo, someone knocked on his door. It was revealed this week that the person who knocked on his door disappeared as soon as he answered it.

Black challenged the person who knocked at his door to face him at Extreme Rules. Many Superstars could answer this challenge including Cesaro, Buddy Murphy, and the most likely option Randy Orton.
Aleister Black and The Viper have done a lot of work with each other on Live Events. He will likely put Aleister Black over thanks to his status as a legend.
