#5 The Miz has wrestled a record of four IC title matches at SummerSlam
There were four Intercontinental title matches at SummerSlam from 2012 to 2016, and The Miz was involved in each of them. The 2014-16 stretch makes Miz the first man to take part in IC title matches at three consecutive SummerSlams. He's also the only man to have wrestled in four Intercontinental title matches on the show, as he won two and lost two of those. Miz's short match with Apollo Crews at SummerSlam 2016 was decent if mostly forgettable, but its existence earns him this unique distinction.
He broke away from Dolph Ziggler and Mr Perfect, both at three, in 2016 but had a chance to extend his lead in 2017, as he was the IC champion heading into SummerSlam. However, he wrestled a six-man tag team match in front of hardly any crowd. Ziggler, the reigning Intercontinental champion, is currently scheduled to defend his title against Seth Rollins at SummerSlam. If this match remains put, the Showoff will equal Miz's record of four Intercontinental Championship matches at SummerSlam.
#4 John Cena ended his six-year SummerSlam losing streak in 2017
Up until SummerSlam last year, Superman John Cena had not reigned victorious at SummerSlam since he made Wade Barrett tap out at the end of the 2010 show. From then on, it was loss after loss, many of those losses in excellent matches with revered in-ring marvels. In 2011, he dropped the WWE TItle unification match to CM Punk, before failing to win a triple threat involving Punk and Big Show the following year. The next four years would see him lose high-profile show-stealers in a bunch of well-received matches.
Cena lost the WWE Championship to Daniel Bryan in 2013, one year before dropping it to Brock Lesnar in a terrifying beating which shocked the WWE Universe to its core. Along with the Jon Stewart-infested title-for-title match with Seth Rollins in 2015, John Cena cleanly put AJ Styles over at SummerSlam 2016 in a match that made Styles a main-eventer. He would eventually end this bitter streak with a pedestrian victory over Baron Corbin in 2017, but this stat is still pretty astonishing. So astonishing that we will it slide that only half of those losses were clean.
#3 The Undertaker was the first wrestler to win 10 matches at SummerSlam in 2015
The Undertaker was the first to ten WrestleMania wins and he takes this cake as well. The Deadman's dubious victory over Brock Lesnar at SummerSlam 2015 marked the tenth time that he would leave SummerSlam with his hand raised, giving him a record of 10-5-1. His 16 matches at SummerSlam are also a record, sitting two ahead of John Cena. While not as illustrious as his list of victims at WrestleMania, Undertaker's SummerSlam sacrifices signify a bizarre Who's Who of different eras of WWE, starting from 1992.
In all, Undertaker racked up summertime wins over a varied bucket of opponents from the likes of Kamala, Giant Gonzalez and the fake Undertaker, to Test, Albert, Edge and finally, Brock Lesnar. His SummerSlam 2015 match with Lesnar was also his first one since that Hell in a Cell match against Edge in 2008, with the Deadman making some shocking returns at later editions. The quality of his matches may not have added up like his WrestleMania resume, but this is a fitting tribute to the endurance of The Undertaker, nonetheless.
