#1 Short program before WWE SummerSlam
WWE Extreme Rules is just two weeks away, so WWE would not have been able to build a truly intense rivalry involving Aleister Black for that event.
A lot of fans feel that the WWE Creative has huge plans for Bray Wyatt and Aleister Black at WWE SummerSlam. Thus, the team may have Cesaro feud with the Dutch Destroyer until the Eater of the Worlds confronts him.
To give Black a victory at Extreme Rules is a no-brainer and this filler feud may take place because Aleister Black's vignettes have become monotonous. He will have no momentum by his side heading into SummerSlam if WWE does not book him to wrestle at Extreme Rules.
One can easily imagine Black standing tall after a win over Cesaro and then the Fiend can show up to ignite the rivalry. Black vs Wyatt is a feud that everyone wants to see. This match deserves a marquee stage like SummerSlam hence, WWE is progressing in the right direction by booking Cesaro as Black's opponent at Extreme Rules.
