The 24-year-old became the second American to earn the title, joining mentor Jackie Joyner-Kersee, who won the event for a second time in 1993. Joyner-Kersee, who also two Olympic gold medals, was on hand in Tokyo to support Hall. Jackie and I have talked about it, and we were like, 'The USA does make great heptathletes.' It means the world to be able to bring the title back home where it belongs.'
