A U.S. boxing program struggling in recent Games received a double infusion of success Monday when female fighters Marlen Esparza and Claressa Shields won quarterfinal matches and assured the U.S. of at least two bronze medals. Each still has a chance for gold in the first Olympics for women's boxing. Esparza, a flyweight, beat Venezuela's Karlha Magliocco. Sheilds, 17, a middleweight, closed furiously in an 18-14 win over Sweden's Anna Laurell.
All-around champ Gabby Douglas, who also helped the U.S. women to team gold, finished last on uneven bars. Aliya Mustafina, who injured her left knee in April 2011, rallied to win the event, giving Russia its first gold. "I made a little mistake and paid for it," said Douglas, who hesitated as she pirouetted on the high bar. Mustafina, China's He Kexin (silver) and Britain's Beth Tweddle (bronze) had harder routines than Douglas. Also, Arthur Zanetti gave Brazil its first medal in gymnastics, upsetting "Lord of the Rings" Chen Yibing for the gold on still rings.
