Shirai wins floor; U.S. takes double in vault

ANTWERP, Belgium —

Led by 17-year-old Kenzo Shirai on the floor, Japan’s men’s team added two more gold medals at the world gymnastics championships on Saturday, while the U.S. women won their second gold-silver double in two days.

Shirai had the performance of the day, as he finished an already impressive floor routine chockfull of twists before finishing it off with a quadruple twist — becoming the first person to pull off the move in a major event final.
