Erriyon Knighton, a rising junior at Tampa Hillsborough High in Florida and representing My Brother's Keeper Track Club, joins DyeStat's Todd Grasley to discuss his age 16 national record after running 20.33 seconds in the 200 meters Aug. 7 at the AAU Junior Olympics in Brevard County. Knighton also ran 10.29 in the 100-meter dash to win the AAU 15-16 national title in that event as well. Only Usain Bolt, who ran 20.13 in 2003, has run faster at age 16 than Knighton.
