Simone Biles won a record-extending ninth U.S. all-around gymnastics title Sunday, signalling she's a force in the sport as the Paris Olympics approach, even as a couple of miscues gave her something to work on before the U.S. trials.

"Today, it's just getting out here, getting comfortable and confident in my gymnastics, and hopefully going to Olympic trials and making that next step towards Paris," Biles told broadcaster NBC after piling up 59.300 points on the second night of competition to take her total to 119.750.

She was almost six points clear of runner-up Skye Blakely, who totaled 113.850 with Kayla DiCello taking bronze with 110.800.
