The 17-year-old Australian of the South-Sudanese heritage bag The title of the national 200m two days after winning the 100m race.
The teenager Gout Gout has reinforced her growing reputation as one of the best young sprinters in the world by blocking a title of 19.84 seconds assisted by the wind to win the 200 -meter Australian title.
Its puffed race on Sunday was the second fastest of all time by an athlete less than 20 years in all conditions, exceeding the 19.93 of Usain Bolt in 2004 and 19.86 by Justin Gatlin in 2001.
Friday, he followed the 100m crown at the Australian Athletic Championships in Perth in 9.99 seconds.
This was also done with a rear wind slightly above the authorized limit, so it will not make the records.
Its rapid development arouses growing interest, with the light schoolboy described this year by the president of world athletics Sebastian Coe as a rare talent.
“It really feels good, that’s what I continued,” said Gout after breaking the 20 second barrier.
“The top speed is my gift. I used it, I took off and I got the least, so I couldn’t be happier.”
Gout, who was born in Australia after his parents emigrated from South Sudan, took importance in December when he managed the fastest 200m of 16 years by a 20.04 seconds, improving the Bolt record at the same age.
He had to keep his nerve in the 200m race after two athletes were false, including the main challenger Lachlan Kennedy, before the drop explodes from the blocks and leaves the rest in its wake.
“I was a little nervous,” he admitted. “But in my head, I just keep my composure, I calm down, because this thing happens, you can’t really control it.
“So I made sure I was not starting or was not unstable, and I took off.”

In December, Coe called the rare talented drop, but said that it would need to “feed and protect”.
The tagged athlete inevitably made comparisons with eight times the bolt Olympic gold medalist at the same age.
But Coe said that the teenager had to be carefully manipulated.
“He is clearly talented, but there is also a little realism here,” said the chief of athletics.
“It is an exceptional talent. But I think that anyone you are talking about in the upper levels of the Australian coach and here in World Athletics will tell you that the biggest training challenge is to take a very talented 17 to 18 years in the upper levels of senior teams.”
Coe added: “We must be realistic on this subject … The vast majority of people who win the world junior titles do not compete for their national team at the senior level.
“This is a rare and precious talent that will need care and protection.”
