Hall is one of the American medal hopes for the 2014 World Junior Championships in Athletics. On 27 July, Hall earned the silver medal at the 2014 IAAF World Junior Championships. Hall's time of 12.92 seconds in the 100 meters hurdles broke the 35-year-old US High School record of 12.95 held by Candy Young of Pennsylvania. Hall's finish behind University of Georgia freshmen, Kendell Williams, completed a one-two sweep of the medals for the US.
