Teenager Gout Gout set a new Australian record with victory in the men's 200m on his senior international debut at the Golden Spike meeting in Ostrava.
The 17-year-old clocked 20.02 seconds in a highly anticipated first European meeting in the Czech Republic.
The sprinter powered past Portuguese-based Cuban Reynier Mena, who had to settle for second after winning the last two Diamond League 200m races.
Britain's Nethaneel Mitchell-Blake finished third with a season's best 20.60.
Gout has been compared to legendary eight-time Olympic gold medallist Usain Bolt, and his 200m time in Ostrava was better than that of Jamaica's world record holder, who finished in 20.28 on his first Golden Spike meet in 2006.
However, Gout is yet to run a legal time under 20 seconds, which Bolt achieved four months before his 18th birthday with a 19.93 in Bermuda.
Gout's previous personal best was 20.04, which he ran last December to break Olympic silver medallist Peter Norman's long-standing Australian record.
Gout has stepped up to senior level after dominating youth meetings.
He holds the Australian under-16 records in both the 100m and 200m, and last year won the national under-20 100m title before securing a 200m silver medal in the World Under-20 Championships in Lima.
Following last year's victory in the 200m and 400m at the 2024 GPS Track & Field Championships in his native Queensland, Gout turned professional and signed a sponsorship deal with Adidas.
He will continue his preparation for September's World Championships by competing at the Monaco Diamond League meet at Stade Louis II on 11 July.
This year's World Championships will be held from 13-21 September in Tokyo, Japan.
Pole vault world record holder Armand Duplantis was one of four athletes to set new Golden Spike records.
Sweden's Olympic and world champion, who broke the world record for a 12th time with a clearance of 6.28m at the Diamond League meeting in Stockholm this month, claimed victory with 6.13m in Ostrava.
Duplantis said he was pleased with his performance despite failing with his three attempts at 6.29m and a new world record.
"I felt good with the jumps, considering I felt as though I was operating on less than a full tank," said Duplantis.
Kenyan teenager Phanuel Koech, 18, also set a meeting record in the men's 1500m with a time of three minutes 29.05 seconds, while South Africa's world indoor champion Prudence Sekgodiso clocked one minute 57.16 seconds to claim victory in the women's 800m.
In the women's 400m, Bahrain's former world champion Salwa Eid Naser broke home favourite Tatana Kocembova's 42-year course record with victory in 49.15 seconds.
Elsewhere, Britain's Samuel Reardon finished second in the men's 400m, and Olympic silver medallist Amy Hunt came fourth in the women's 100m.
