BUDAPEST, Hungary — After swimming for almost two hours in open water, Olympic champion Ferry Weertman edged defending champion Jordan Wilimovsky by one tenth of a second for the 10-kilometer title at the World Championships on Tuesday.

Weertman earned the Netherlands' first medal of the championships, on Lake Balaton, about 130 kms (80 miles) southwest of Budapest.

"I just love swimming ... I haven't stopped for a moment, and this hard work paid off," said the 25-year-old Weertman, who began swimming at age 6 because his brother made it look like fun.

Wilimovsky had no regrets, despite the closest of finishes. "I cannot complain about my swim. I tried everything I could. There are plenty of very good swimmers in the 10k, so the silver medal is all right," the American said.

Marc-Antoine Olivier of France, who won the 5K on Saturday, was 0.70 seconds behind for bronze. He became the first Frenchman to win more than one medal in open water swimming at the worlds. Neither Weertman nor Wilimovsky raced the 5K.

Russia later won its sixth straight women's team technical synchronized swimming title for its fourth gold medal of the championships.

The team of Maria Shurochkina, Vlada Chigireva, Veronika Kalinina, Daria Bayandina, Anastasia Bayandina, Maryna Goliadkina, Darina Valitova, and Polina Komar performed last and maintained the team's unbeaten record in the event with 96.0109 points.

"There is no limit to perfection," said Chigireva, one of only two swimmers alongside Shurochkina left from the team that won Olympic gold in 2016. Shurochkina said the new members "took the challenge and they really mingled with us, they are now part of the team."

Chinese swimmers Wang Qianyi, Wang Liuyi, Guo Li, Xiao Yanning, Tang Mengni, Feng Yu, Liang Xinping and Yin Chengxin claimed silver with 94.2165, followed by Japan on 93.1690 for its first medal of the championships.

Chigireva and Shurochkina equaled Daria Korobova's three gold medals in this event. Only Russian compatriots Aleksandra Patskevich, Alla Shishkina and Angelika Timanina have more with four.

The United States defeated Spain 12-8 to stay unbeaten in its defense of the women's water polo title on Tuesday. The US, Olympic champion and winner of every major competition since the 2013 worlds, leads Group B with maximum points from two games.

Spain and New Zealand have one win each after the latter's 8-6 win over South Africa. The Netherlands, the 2015 silver medalist, defeated Japan 12-6 in Group C.

On Monday, Italy provided a brief distraction from Chinese domination of diving at the world championships when Giorgio Minisini and Manila Flamini claimed a gold medal in synchronized swimming on Monday.

China repeated its feat of Sunday when it won both finals, making the disappointment of 'only' one medal on Saturday an aberration.

Shi Tingmao and Chang Yani won the team's ninth straight world title in women's 3-meter springboard synchronized diving, then Chen Aisen and Yang Hao delivered China's fifth gold of the championships in the men's 10-meter platform.

Chen and Yang, who won the 10-meter platform in all four meets of the diving world series this season, led from the start and finished with their best dive of six for a total of 498.48 points.

It was Chen's second gold in this event after winning at the 2015 worlds with Lin Yue. "The last time was a more relaxed competition," Chen said.

Russia's Aleksandr Bondar and Viktor Minibaev, almost 40 points behind, came closest to the Chinese for the silver, and Germany's first medal of the week went to third-placed Patrick Hausding and Sascha Klein.

The Germans equaled the record of three medals in this event at the worlds, after winning in 2013 in Barcelona and claiming silver in 2011. "We couldn't be more satisfied," Hausding said

Shi and Chang upheld China's winning streak from Sunday. They also led from the first round and produced an almost-perfect forward 2-1/2 somersaults, one twist pike in the fifth for a total of 333.30.

It brought Shi her sixth gold medal in diving at the worlds and her fourth in this event.

Shi said: "First of all, I feel really happy we won this gold medal, and then I would like to mention that my partner is only 15 and (this) was her first (worlds), so I feel very happy for her."

Melissa Citrini Beaulieu and Jennifer Abel finished with an inward 2-1/2 somersaults pike to claim Canada's first medal of the championships, a silver, with 323.43.

Abel claimed a medal in this event at the previous three worlds, and her fourth made her the most decorated non-Chinese athlete in women's 3-meter springboard.

Kristina Ilinykh and Nadezhda Bazhina won the bronze for Russia, its first of the championships and sixth at the time. Bondar and Minibaev made it seven later.

In men's water polo, Canada came from four goals down to draw with Montenegro 8-8, and Croatia beat the United States 12-7. Croatia is the only team to have won a medal at each of the last five worlds. Defending champion Serbia had no problems with a 21-5 rout of South Africa. — AP
