#3.) Brock Lesnar vs CM Punk – SummerSlam 2013
Punk vs Lesnar was advertised as The Best vs The Beast. It was an emotional storyline that saw Paul Heyman turn his back on CM Punk in favour of Brock Lesnar. The two would have a collision course at SummerSlam and it was one for the ages.
The non-title bout was up there as one of the best matches in 2013 that saw CM Punk fall short to The Beast Incarnate. CM Punk later revealed on his infamous podcast with Colt Cabana that he wasn’t happy about the decision to lose to Lesnar. It would be only five months before he left WWE and pro wrestling for good.
