Mai Murakami finished third on Saturday in the women's all-around competition at the American Cup, a tournament on the FIG World Cup series.
Murakami scored 55.732 points in the competition, at Greensboro Coliseum Complex, won by American 15-year-old Leanne Wong, who was making her debut in a senior competition.
A silver medalist at last year's world championship, Murakami fell from the balance beam while attempting a new technique, which involves spinning three times after squatting down.
She secured a podium finish after scoring 14.133 points in the floor exercise, the final routine.
"It's frustrating that I made the mistake, but I was trying out a new technique so I shouldn't really be upset about it," she said. "I think I would've done really well if I nailed that one technique. I see myself making huge improvements."
