At Money in the Bank on July 6, Tonga, along with Sikoa and the debuting Jacob Fatu, defeated Cody Rhodes, Orton and Owens at in a six-man tag team match, with Sikoa pinning Rhodes. In the main event of the August 2 episode of SmackDown, the night before SummerSlam, Tonga and Fatu defeated DIY (Johnny Gargano and Tommaso Ciampa) to win the WWE Tag Team Championships, marking Tama's first title win in WWE.
