NANJING China American teenager Noah Lyles stormed to victory in the men's 200 meters sprint on Sunday to provide the United States with their first gold medal in track and field at the Youth Olympics in Nanjing, China.
The 16-year-old lived up to his billing as the pre-race favorite as he charged to victory in 20.80 seconds.
"I took the win from the Jamaicans. I took the win from everybody else. I definitely wanted to prove that we're (U.S.) still on top," he said.
"Coming in with a big target on your back, there's always pressure. But you can't worry about it, you've just got to run your own race and do the best you can."
Jamaica did win the women's 200m final when Natalliah Whyte scored in 23.55 seconds on the busiest day of the Games, with 33 gold medals decided, including 12 in athletics.

Gabriel Luis Moreno made it the archery field just in time to join forces with China's Li Jiaman and win the mixed international team event.
Moreno almost missed his event after his taxi driver got lost but got there in the nick of time.
"I had to go into the quarter-finals with almost no warm up time," he said. "But thankfully, that did not harm my performance."

New Zealand's Emily Fraser managed to break Europe's domination of the equestrian events when she won gold after a jump-off.
