The U.S. women left no doubt about defending their world gymnastics title, leading the team competition wire-to-wire in Nanning, China, on Wednesday.
The victory followed team golds at the 2012 London Olympics and the previous world championships in 2011.
"Everyone hit all their events," Alyssa Baumann said. "We did such a great job."
China finished second and Russia took the bronze medal.
The Americans were led by world all-around champion Simone Biles, who secured the win with a 15.375 on the floor event. Kyla Ross, nursing a hip injury, competed in all four events.
"Overall today, it went really well for every single girl that competed," Biles said. "We had a couple of mistakes, at least I did, but other than that it went really well."
