ANTWERP, Belgium (AP) -- Aliya Mustafina won Russia's first gold medal of the gymnastics world championships, edging Kyla Ross of the U.S. on the balance beam on Sunday.
Mustafina, the 2010 all-around champion, was near flawless as she twirled, twisted and jumped at will on the narrow beam, and then watched Ross and all-around champion Simone Biles fall short of surpassing her. It was Ross' third silver of the championships. Biles took bronze.
In the men's vault, South Korea's Yang Hak-seon continued to dominate. The defending and Olympic champion brought a difficult new vault to Antwerp and used it well enough to slip past American rival Steve Legendre. Kristian Thomas of Britain took bronze.
The women's floor and the men's parallel bars and high bar were set for later Sunday.
