DOHA -- Kenneth Bednarek sounded out a warning to his Olympic rivals with a personal best and world-leading time in the 200 meters when he led an all-American podium at the Diamond League meeting in windy conditions in Doha on Friday.
Wearing a headband with the words "Fear no one", Bednarek was in lane seven but the Tokyo Olympics silver medalist stormed to the finish line with a time of 19.67 seconds.
Courtney Lindsey finished second (20.01), while Kyree King (20.21) was third.
"The best I can do this year is gold medal in the Olympics... I know I have the talent and good training. Running this fast this early is really good, it means I will be fast by the time we start the Olympics," Bednarek said.
"Time doesn't matter, my main focus is not the time, but competing and making sure we get the job done."
In the women's 100 meters, Britain's Daryll Neita edged ahead of American Tamari Davis in the final 15 meters to win by one-hundredth of a second in a photo finish for the podium.
Neita won with a time of 10.98 while American Celera Barnes was third (11.02).
But it was Alison dos Santos who got the crowd going when he broke the meet record in the 400m hurdles as the towering Brazilian left his opponents far behind to clock 46.86 seconds.
In the men's long jump, Greece's reigning Olympic champion Miltiadis Tentoglou finished second behind Jamaica's Carey McLeod who won with a leap of 8.52 meters thanks to a strong tailwind.
Tentoglou, who was competing in his first event this year, could only manage 8.36 on his final attempt.
McLeod went viral last year at the World Athletics Championships when he slipped during his run-up, flew through the air and landed awkwardly face-first but walked away without any serious injury.
India's Olympic champion Neeraj Chopra was pipped to top spot in the javelin by the Czech Republic's Jakub Vadlejch in a close contest where the pair were separated by just two centimeters.
Chopra was looking to beat Vadlejch's best throw of 88.38 meters but his final effort fell agonizingly short as the two athletes smiled and shook hands.
The Diamond League season continues in Rabat on May 19, the fourth of a bumper 15 meetings that have been scheduled this year. The season finale is in Brussels in mid-September following the July 26-Aug. 11 Olympics in Paris.
