With this tremendous record, Chopra not only joined a cream of the crop list of Indian athletes to win a gold medal on their CWG debut but also became the first Indian to win in Javelin Throw at CWG.
In a high quality display, his lowest throw came at 83.48m - more than the best throw of Australia's Hamish Peacock, who claimed the silver with 82.59m.
Worth mentioning here this is the fourth gold of the day 10 of CWG 2018 for India. He then extended his lead to 86.47 in his fourth throw, which in fact turned out to be his seasonal best.
Chopra's showing in the last one year has escalated the youngster to the same platform, if not above, as country's elite athletes.More news: Attention Gmail users: your emails might 'self-destruct' soon

A farmer's son from a village outside of Delhi, the 20-year-old said staying relaxed was the key after he won by almost four metres from Australia's Hamish Peacock on the Gold Coast. And truth be told, it is hard to argue against either of those statements.
The other Indian competing in the event, Vipin Kashana, finished fifth with a best of 77.87. In August previous year, he won a gold medal at the Asian Athletics Championships in Bhubaneshwar with a mark of 85.23m - the best-ever throw recorded in Indian soil.
It didn't matter that Chopra's javelin could only travel a distance of 86.47m in the final on Saturday, 0.1m shorter than his career best. In August 2017, he won a gold medal at the Asian Athletics Championships in Bhubaneswar with a sensational mark of 85.23m. But he disappointed at the London World Championships, failing to make it to the final round after a best effort of 82.26m.
With his surprise win, Chopra becomes only the third Indian man to win athletics gold at the Commonwealths, after Milkha "Flying Sikh" Singh in 1958 and Vikas Gowda in 2014.
