Watch: 19-Year-Old American Sensation Lights Up Diamond League With 200m Run

Noah Lyles blew away the opposition at the Diamond League meeting in Shanghai on Saturday.

The 19-year-old American ran a personal best and a joint world leading time in the 200m.

Running out of lane eight, Lyles clocked 19.90 into a slight headwind for the race, finishing well ahead of fellow American LeShawn Merritt and British runner Adam Gemili. He's just the fourth teenager ever to run under 20 seconds for the 200m (h/t FloTrack)
