Uganda's Joshua Cheptegei delivered his season's best performance of 27 minutes 51.42 seconds, clinching the men's 10,000m world title for the third consecutive time on Sunday.
Cheptegei, 26, only surged ahead in the final lap, comfortably securing the top spot, even if his time couldn't rival his world record of 26:11.00.
Kenya's Daniel Simiu Ebenso bagged the silver with a time of 27:52.60, while Ethiopian Solemn Brega clinched bronze just 0.12 seconds behind.
"I am very excited and proud that I have succeeded in winning my third world title in a row. This was the best possible way to end the season," Cheptegei remarked. "This might be my last championships on the track. That's why this gold medal means even more."
In the men's 100m, the flagship event of the World Championships, defending champion Fred Kerley faced an unexpected exit in the semifinals. However, his American compatriot Noah Lyles took the baton, recording this year's world-best time of 9.83 seconds.
"I came here for three golds, ticked off one, others are coming," Lyles commented, looking forward to defending his 200m title in Budapest. "The 100m was the toughest. I will have fun with the event I love now."
Botswana's U20 double world champion Letsile Tebogo secured silver, setting a new national record at 9.88 seconds. Britain's Zharnel Hughes trailed just behind.
Italy's Olympic victor, Lamont Marcell Jacobs, despite posting his season's best time of 10.05 seconds, couldn't make it to the final.
Local hero Bence Halasz electrified the home crowd when he hurled the hammer beyond 80m on his initial attempt. Nonetheless, Canadian newcomer Ethan Katzberg seized the lead with his 81.25m fifth attempt. Poland's Wojciech Nowicki also bested Halasz, recording 81.02m.
Halasz eventually settled for third with 80.82m, securing his second World Championships bronze.
