#1 Lesnar vs CM Punk (2013)

This is easily the best match of Brock Lesnar's current WWE run, since returning in 2012. The feud between CM Punk and Paul Heyman was the definition of hit-miss television. While this first portion of the feud was excellent, the rest of it was a bore and felt forced until the final pay-off, that is.
Heyman had betrayed Punk at Money in the Bank, viciously smashing a ladder on his head. The ensuing weeks would see Punk finding innovative ways to get an upper hand on Brock Lesnar. He knew that it would not be straightforward, trying to take down a 300-pound gorilla, so he went to some extraordinary lengths to get to the Beast.

Punk dressed as a cameraman once as he would send Lesnar retreating. He showed no fear. This was the last truly great thing the Second City Saint had done in the WWE. On a SummerSlam filled with some exciting action, this, along with the main event, blew everything else out of the water.
Brock Lesnar works extremely well as a menacing heel trying to destroy smaller babyface opponents. The matches are always enthralling, as we see the underdog work his way up to the layer of the Beast. It has resulted in some of Lesnar's best matches in the WWE. His match with CM Punk is the perfect illustration of this.
Lesnar has also had similar classics against the likes of Eddie Guerrero and AJ Styles, making us hope that we do get the chance to see him face Seth Rollins for the Universal Championship soon. This match was changed to No Disqualification on the night and it made it even better.
Punk would break down the Beast and come close on multiple occasions, using creativity and experience to do so. However, the menacing Paul Heyman would always provide multiple distractions and interferences.
It would be Punk's obsession with getting his hands on Heyman that would prove to be his undoing, as Brock Lesnar took advantage of the distraction to slam the Chicago-born star with a steel chair before hitting a conclusive F5 on it.
The match was an excellent one, perfectly illustrating the difference between the underdog fighter and the physically superior mercenary. Lesnar may have won this war, but it was CM Punk who won the hearts of the WWE Universe. He put in one hell of a performance, not that Lesnar's wasn't great as well.
That is what makes this match the best from all of Lesnar's big matches in August. Punk rightly received a standing ovation, for his last truly big moment in the WWE before his unceremonious departure in 2014. A perfectly executed match in every sense.
