7. John Cena - 11 Matches
John Cena has eleven SummerSlam matches, as do a few others ahead of him on this list. However, Cena ranks seventh, based on the fact he's got an astoundingly bad record of only four wins with seven losses. That's one of the greatest ironies of Cena's career. He's pushed so hard, yet is a massive loser when it comes to WWE's second biggest show of the year. His first SummerSlam was in 2004, with a victory over Booker T. His most recent performance was 2014, infamously being destroyed by Brock Lesnar. The year before that he was defeated by Daniel Bryan, and for two years in a row before that he lost to CM Punk. In fact, he hasn't won at a SummerSlam since 2010. Maybe he's due a 'W' at the 2015 event? Cena will be jumping up to fourth on this list with match number twelve coming against Seth Rollins at SummerSlam 2015.
