Below are some highlights of Night One of WWE's SummerSlam:
- In his first action since WrestleMania 41, Roman Reigns was on the winning end of a tag match, teaming with Jey Uso to defeat the Paul Heyman led duo of Bron Breakker and Bronson Reed.
- The Women's Tag Team titles changed hands as the unlikely duo of Alexa Bliss and Charlotte Flair defeated Judgment Day's Raquel Rodriguez and Roxanne Perez. There was a tease of dissention at the end when Bliss accidentally clocked Flair but the two shook that off to secure the win. Even post-match, the alliance looked shaky, but Flair grabbed Bliss and pulled her in for a hug to celebrate.
- In perhaps the biggest surprise moment of SummerSlam's Night One, after CM Punk defeated Gunther to become the World Heavyweight Champion in a culminating moment, but the title was short-lived as Seth Rollins cashed in his Money in the Bank briefcase and ended the night as champ. Rollins, who suffered an "injury" at WWE Saturday Night's Main Event, was not nearly as injured as he or WWE were leading everyone to believe, came out in crutches but ditched them to surprise Punk and the audience.
