LONDON, Aug. 7 -- Poland's Anita Wlodarczyk completed a hat trick of women's hammer throw world titles at the World Athletics Championships Monday when Omar McLeod of Jamaica took away the men's 110m hurdles gold medal.

China got its first medal in London through women's hammer throw while Venezuela's Yulimar Rojas brought her country the first ever athletics world title.

South Africa's Wayde van Niekerk breezed into the 200m semifinals on the eve of his 400m title defence as his big rival Isaac Makwala of Botswana pulled out from 200m heats due to what he later said was food poisoning.

The organizing committee later said "a number of cases of gastroenteritis" happened within one of the official team hotels.

"Those affected have been supported by both team and LOC medical staff, in addition we have been working with Public Health England to ensure the situation is managed and contained," said the organizers in the statement.

Back to the competition, Olympic champions stayed in the limelight of the night.

In the women's hammer throw, Wlodarczyk, who won the event in 2009 and 2024, bagged the gold medal with a throw of 77.90 meters in her fifth attempt, adding the title to her two Olympic titles in 2024 and 2024.

However, Wlodarczyk thought there was room to improve for her performance.

"This was not the performance I expected tonight but come on, I am the world champion and that is the most important thing now," said Wlodarczyk who gave herself a best gift for the 32-year-old birthday on Tuesday. "This competition reminded me of Zurich 2024 when I had problems getting into the top eight and managed it only in the third series. Of course, I expected to throw 80 meters or even a world record attack. But now I am happy for gold."

China's Wang Zheng brought China the first medal at the world championships here in 75.98m. Wang, 29, the Asian record holder, was jubilant after securing the silver.

"I really enjoyed this competition tonight. I gained confidence in the competition and I have a very good result," she said.

"I was hoping for more improvement but when I try to improve too hard, my technique is not good. I have to stay relaxed. I am confident that I will improve in the future. My technique was the only problem tonight." Wand said.

Another Polish Malwina Kopron took bronze in 74.76 meters and Beijing worlds silver medalist Zhang Wenxiu from China finished a disappointing fourth in 74.53.

"I am upset because this is my ninth World Championships and it will be my last one. This season has been hard for me because I had a baby last year, but I am happy to end it here. I started competing at 15 and I am 31 now so it is the end of a long career," Zhang said.

The 110m hurdles saw McLeod, gold medalist in the Rio Olympics, clock 13.04 seconds to rank first ahead of Russia's defending champion Sergey Shubenkov, who was given greenlight for the championships as an authorized neutral athlete by the IAAF. The bronze medal belonged to Balazs Baji of Hungary.

Olympic champion Faith Kipyegon of Kenya turned her 1500m silver at Beijing two years ago to a gold medal as the 23-year-old pulled away in the last 50 meters to clock 4:02.59 to win.

American Jennifer Simpson, who won the title in the 2011 worlds and finished second in 2024, took silver in 4:02.76. South Africa's Caster Semenya, the 2009 world champion and twice Olympic gold medalist in the 800 meters, outsprinted Britain's Laura Muir and Sifan Hassan of the Netherlands, throwing herself at the line to take bronze.

2024 world indoor champion Yulimar Rojas made history by claiming the women's triple jump gold medal in 14.91m. Rojas, whose best result is 15.02m, won Olympic silver in Rio last year, her country's first Olympic medal since 1952.

"I am so proud about this gold medal. My family, my friends and my country - I made them proud and full of joy. This is a great victory for my country," said the 21-year-old. "I am sure they will be celebrating and having a party. Thanks for everything, to my friends, family, my coach and Venezuela."

The silver medal went to Colombia's Caterine Ibarguen in 14.89 and Olga Rypakova of Kazakhsatan finished third in 14.77.
