NANNING, China (AP) Simone Biles of the United States capped her dominance at the gymnastics world championships on Sunday, winning gold medals on the balance beam and the floor exercise on the final day of competition.
Biles earned 15.100 points for a solid routine on the beam that opened with a well-controlled double squat turn and included three back handsprings.
''I just wanted to go out there and hit all my routines, it was a lot of fun,'' Biles said. ''I'm looking forward to the next world championships and hopefully the Olympics in 2016.''
Bai Yawen of China won silver with 15.033 points while Aliya Mustafina of Russia claimed the bronze with 14.166.
Biles won her fourth gold of the meet with a powerful routine on the floor that received 15.333 points. Larisa Iordache of Romania was second with 14.800, followed by Mustafina with 14.733.
Biles previously won gold medals in the team event and the all-around competition where she defended the 2013 title won in Antwerp, Belgium.
Her six career gold medals at the world championships are the most by a U.S. woman, surpassing the five by Shannon Miller in her career.
''It blows my mind,'' Biles said of the new mark. ''It's an incredible honor and I'm so happy.''
The United States finished with a total of 10 medals - four gold, two silver, four bronze.
Oleg Verniaiev of Ukraine won the gold medal in men's parallel bars with 16.125 points, ahead of Danell Leyva of the United States, who took the silver medal with 15.933. Ryohei Kato of Japan won the bronze with 15.666.
Epke Zonderland of the Netherlands won the horizontal bar title with 16.225, edging five-time all-around world champion Kohei Uchimura of Japan, who was second with 15.725. Marijo Moznik of Croatia was third with 15.000.
