At the 2014 World Junior Championships in Eugene, Oregon Jones won gold in the long jump, jumping 6.34 m into a strong headwind; she was the first Barbadian ever to win a World Junior Championship medal. She also qualified for the high jump final, but decided to skip it after the long jump gold to avoid aggravating a minor knee problem. In recognition of her achievements in 2014, Jones was named Barbadian Sportspersonality of the Year.
