Simone Biles claims historic 13th world title but suffers first defeat in Doha

Every time Simone Biles takes to the floor, she makes history.

Last night, she became the first woman to win four world all-around titles.

Today, she took the vault title for a 13th gold medal making her the most successful athlete in the history of the World Artistic Gymnastics Championships, breaking a tie with Belarus' Vitaly Scherbo.

“I really wanted to come out here and redeem myself, and I think I did that tonight,” she said of shaking off the mistakes in yesterday’s all-around final.

But Biles' perfect record in Doha was ended in the uneven bars as she took silver behind Nina Derwael.

This was the American's first global medal in what has long been her weakest event, with Derwael winning Belgium's first artistic gymnastics world title.

Firsts for Biles

Biles may be Olympic vault champion, but she had not won a world title in the event until today.

The 21-year-old, four-time Olympic gold medallist opted not to have another go at 'the Biles' having fallen when she tried to land it yesterday.

But her less difficult vaults still propelled her to the top of the podium, beating Canada’s Shallon Olsen by 0.850 points with Alexa Moreno of Mexico taking bronze.

Biles has now won 18 medals in the 19 world finals she has made, the one blip coming in the 2013 uneven bars.

She finished fourth there, but in Doha she took the silver.

“I’ve come a long way and I’m really pleased with the performance I put out today,” she said. “I really put the work and the effort to bring up that event to the level with the others.”

She could tie Russia’s Svetlana Khorkina on a women's record 20 medals tomorrow in the balance beam and floor exercise finals.

And with Biles telling Olympic Channel earlier on Friday that she plans to compete in next year's World Championships in Stuttgart, Scherbo's total of 23 medals is under threat.

Delight for Derwael

Nina Derwael beat Biles to take gold on the uneven bars with an acrobatic routine.

After taking bronze 12 months ago, the 18-year-old impressed in finishing fourth in yesterday's all-around.

But now she is a world champion.

“It’s just all a dream come true,” Derwael said. “I don’t know what to say, I don’t have any words. It’s just incredible.”

Veteran Chusovitina just out of the medals

Oksana Chusovitina competed in her 14th vault final at the World Championships, aged 43.

She’s only missed the final in two of her 16 appearances.

“I don’t get tired,” she said. “It brings me a lot of pleasure and makes me happy.”

She finished in fourth place, just outside the medals having upgraded her vaults from last weekend’s qualification rounds.

“I have to try more difficult vault because I am preparing for the Olympic Games. That's my goal.”

If Chusovitina makes Tokyo 2020 she would join Canadian rower Lesley Thompson who is currently the only woman to appear at eight Games.

“There is no secret. You have to love what you do,” she said.

Double for Dalaloyan

Russia’s all-around champion Artur Dalaloyan won his second gold of the week in the floor final.

He was the last to go and knew exactly what he needed to take the title away from defending champion Kenzo Shirai.

He delivered a 14.900 to sneak past the Japanese who had scored 14.866 going second.

But the highlight of the floor final came when the Philippines’ Carlos Edriel Yulo grabbed his country’s first-ever medal at the World Artistic Gymnastics Championships.

Yulo said, "I wasn’t expecting this. I’m shocked. I thought I was going to be fifth or sixth."

Whitlock denied, Petrounias delivers

After missing out on the all-around title on a tie-break, China's Xiao Ruoteng came out on top on the pommel horse when he and Great Britain’s Max Whitlock both posted scores of 15.666.

Xiao took the gold by virtue of higher execution marks and denied reigning Olympic champion Whitlock a hat-trick of titles on the pommel horse.

It ends an up-and-down season for the Briton who also failed to win titles on his signature event at both the Commonwealth Games and the European Championships.

With surgery scheduled for Monday, Olympic champion Eleftherios Petrounias almost didn’t compete at these championships.

Instead, he soldiered on through his rings routine to do what Whitlock could not, and claim a third straight world title to go with his Rio 2016 gold.

The Greek said, "I just proved to myself that I can win with a very good mentality, and not tons of training.

"I put all my experience into this competition to win. And it happened.”
