#4 CM Punk: SummerSlam 2013

We'd come to learn later that CM Punk wasn't too happy with the booking behind this match, but it's safe to say that Punk made all of us believers on this night. The Best vs. The Beast was such a fantastic build and the match itself was incredible, and although most people knew that Lesnar wasn't going to be pinned here, Punk gave it his best shot, and made it into a very competitive match.
The storytelling and the action was fantastic throughout, but at the end of the day, the combination of Paul Heyman and Brock Lesnar was just too unbeatable around this time.
This would end up being one of the last big matches of CM Punk' illustrious WWE career, and apart from the John Cena match at Money in the Bank, this may be the best match of Punk's career, as it's one you need to go back and watch multiple times.
