American Judo competitors have won 14 medals in the Olympic Games since the sport's inclusion. Kayla Harrison (78 kg.) successfully defended her 2012 Olympic gold medal in Rio de Janeiro, Brazil, and Travis Stevens (81 kg.) claimed silver. The U.S. currently holds one medal each in the lightweight (70 kg.), middleweight (75 kg.), and heavyweight (90 kg.) weight classes. Harrison is the most decorated American judoka with six victories. She first captured the public's attention when she became the youngest ever world champion at age 21. At the 2012 London Olympics, she added another gold to her resume by defeating Japan's Yumie Hara in the final. In 2016, Harrison announced that she was leaving the sport to focus on her career as a professional wrestler. Stevens' success as a judo player came shortly after Harrison's achievement. He entered his first Olympic tournament as the number-one seed but was defeated in the quarterfinals by Russia's Vladimir Nikitin. At the 2014 Winter Olympics in Sochi, Russia, Stevens again reached the semifinals before being eliminated by France's Patrice Bartoli.
