#4 John Cena - Summer Slam 2014
Despite being one of the greatest performers to ever grace the squared circle, John Cena has never enjoyed a fair amount of success at SummerSlam.
Whilst he has been presented strongly in most of his losses, the Cenation Leader was completely exposed at SummerSlam 2014, where he defended his WWE World Heavyweight Championship against Brock Lesnar.

With Vince McMahon wanting to propel Brock Lesnar as the most destructive force in the company, the Mayor of Suplex City went on to annihilate the 16-time World Champion in front of a stunned audience.
Lesnar wasted no time in getting the offense on Cena, with the current Universal Champion delivering a quick, vicious F-5 in the very first minute of the showdown.
Moreover, Cena became an unfortunate recipient of 16 German Suplexes and whilst he did play his role to perfection, he literally couldn't handle the Beast when it mattered the most.
