Robert Griffin III held the AAU Junior Olympic Games 15-16 year old 400mH national record of 51.77 for almost 20 years before this past Monday. That's when Amari Scott of Decatur, Georgia, broke the record, running 51.30. His time also ranks as the sixth-fastest time of the year and one of the top 10 sophomore performances all time. #AAUJROGames Website: http://flosports.link/3p20lTj Subscribe: http://flosports.link/3p4YLQp Get the FloSports iOS app: http://bit.ly/FloTrackiOSApp_9 Follow FloTrack Facebook: https://www.facebook.com/FloTrack Twitter: https://twitter.com/flotrack Instagram: https://www.instagram.com/FloTrack
