#3 Rusev vs Big Show, Fastlane 2017
Post the Jinder-Cesaro match, Rusev waited for his opponent in the ring and it turned out to be none other than the Big Show. With Rusev not being able to gain any momentum, the giant manhandled him. After hitting 3 Choke slams and one KO Punch, Big Show pinned the Bulgarian Brute in what was a glorified squash match.
#4 Heath Slater vs Curt Hawkins, Great Balls of Fire,2017
YES! This happened! Shocking, isn’t it? An underdog facing a man on a never-ending losing streak on a WWE PPV’s main card. This unannounced match-up took place as a filler and even the result wasn’t broadcasted live as the cameras cut to the fire department to show the aftermath of the ambulance match between Roman Reigns and Braun Strowman but as per the live audience Slater pinned Hawkins to win his first singles PPV match in a long time.
Filler matches are one of the main reasons WWE has done away with single-branded pay-per-views as dual-branded events stop the undercard fro getting exposed.
