The battle continued and included Punk locking Rhodes in the Anaconda Vice submission. Punk also hit a moonsault from the top rope and kicked out of Cross Rhodes. Rhodes maintained pace with Punk and kicked out of the GTS.

Randy Orton returns to WWE at SummerSlam

Near the end of the match, Randy Orton made his return. Orton ran into the ring while Rhodes was in it and the referee was down with Punk on the outside of the ring and hit Rhodes with an RKO. Orton hadn't been seen in WWE since WrestleMania 42.

After that, Punk rolled back into the ring, connected with a GTS, and made the cover for the win. Punk celebrated in the ring with the title and the audience.

Punk wasn't the only champion to retain his title at SummerSlam on Saturday night. In the opening contest of the show, Liv Morgan defeated Iyo Sky to keep her hands on the WWE Women's World Heavyweight Championship. Sky countered Oblivion, but was then tagged with a Codebreaker right after. Morgan was then able to hit Oblivion for the win.

Night two of SummerSlam is on Sunday. In the main event, Seth Rollins will challenge Roman Reigns for the WWE World Heavyweight Championship. Rollins is attempting to re-secure the title he never lost and Reigns is trying to get his first definitive win over Rollins since their days together in The Shield.

Other announced matches for night two include Chad Gable vs. Penta for the WWE Men's Intercontinental Championship and a ladder match to crown an interim WWE Women's Champion.
