BOCHUM, Germany, July 22 (Xinhua) -- Bayanda Walaza sprinted to the men's 100m title to give South Africa its third gold medal at the Rhine-Ruhr World University Games, while Team USA continued to dominate the swimming pool with four more golds on Tuesday night.

The Paris 2024 Olympian and world junior champion crossed the line in 10.16 seconds, edging Thailand's Puripol Boonson (10.22), the same rival he beat at last year's under-20 global competition in Peru. Asian champion Hiroki Yanagita finished third, just 0.01 seconds behind Boonson.

"I feel glorified. I believe in winning. As soon as I was on that [start] line, I was looking at that finish line. My mind was there. I need to cross it before everyone," said Walaza, who, at just 18, ran the leadoff leg in the men's 4x100m relay final to help South Africa claim silver at Paris 2024.

Walaza became just the ninth South African to break the 10-second barrier in the 100m when he clocked 9.94 in Zagreb in May. Weeks earlier, he set a national junior record of 20.08 in the 200m.

Australia's Georgia Harris won the women's 100m in 11.44, ahead of Poland's Magdalena Stefanowicz (11.49) and South Africa's Gabriella Marais (11.51).

Germany claimed a one-two finish in the men's discus, with Mika Sosna winning gold with a throw of 64.26 meters and Steven Richter taking silver at 61.77. Ukraine's Mykhailo Brudin posted a season-best 60.71 to earn bronze.

The women's long jump podium was separated by just three centimeters. Portugal's Agate Sousa leaped 6.60 meters, two centimeters ahead of China's Asian Games champion Xiong Shiqi, who finished one centimeter ahead of Spain's Natalia Gonzalez.

"It's a pity to miss the top place by just two centimeters," said Xiong, who earned China's first athletics medal at the Games. "But the result is compatible with my capability and my expectation. I want to inspire my teammates in the upcoming track and field competitions with this very first medal in the stadium for China."

Swedish Olympian Axelina Johansson won the women's shot put with a throw of 18.45 meters. American top qualifier Abria Smith followed with 17.38, while South Africa's Colette Uys claimed bronze at 17.34, narrowly ahead of compatriot Mine de Klerk by one centimeter.

Seven finals were contested in the pool, with Team USA winning four. The American men continued their relay dominance with a record-breaking win in the 4x200m freestyle, finishing in 7:04.51 to break the previous Games mark of 7:05.49 set by Russia in 2013.

Cavan Gormsen surged from eighth to first on the back half of the women's 200m freestyle, winning gold for the U.S. in 1:57.21. She closed the final 50 meters in 29.13 to pass three swimmers and edge China's Ai Yanhan by 0.3 seconds.

Leah Shackley broke her own day-old meet record to win the women's 50m backstroke in 27.31 seconds, trimming 0.3 off her semifinal time of 27.66.

In the women's 200m individual medley, another American, Leah Hayes, won gold in 2:09.48, improving on her Games record from the semifinal.

Competing as a neutral athlete, Aleksandr Stepanov won his second freestyle distance title of the meet with victory in the men's 800m in 7:46.51, finishing nearly four seconds ahead of Italy's Tommaso Griffante.

Italy's Gianmarco Sansone claimed gold in the men's 100m butterfly with a personal-best 51.40. Germany's Bjorn Kammann finished second in 51.70, followed by Uzbekistan's Eldorbek Usmonov (51.84).

Federico Rizzardi earned Italy's second gold of the session, winning the men's 50m breaststroke in 27.14, nearly 0.2 seconds ahead of the field.

In diving, China's Zhang Wenao won gold in the men's 1m springboard with 425.85 points, followed by teammate Hu Yukang (368.75). Germany's Tim Axur took bronze with 354.80.

South Korea claimed its fifth fencing gold by edging France 45-43 in the women's sabre team event. Italy secured its third fencing title with a commanding 45-20 win over Poland in the men's foil team final.

The top three on the medal table remained unchanged after the sixth day of competition. The U.S. leads with 21 golds (20 in swimming), 12 silvers and 20 bronzes, followed by China (12-17-4) and South Korea (11-5-13). Host Germany sits fourth with seven golds, six silvers and eight bronzes. ■
