Tokyo Olympics: Sky Brown becomes GB's youngest ever medallist with skateboard bronze - as nation improves medal tally

Sky Brown, 13, has won a bronze medal in the women's skateboard event - making her Great Britain's youngest ever medallist - as Katarina Johnson-Thompson found herself out of contention for a medal in the heptathlon.

The teenage skateboarder had qualified in second place for the final at the Ariake Urban Park, with a best score of 57.40.

After falling in her first two runs of the final, she nailed her last attempt with a score of 56.47 to finish behind Japanese pair Sakura Yosozumi, 19, and Kokona Hiraki aged 12.

Yosozumi topped the podium with a score of 60.09, while Hiraki's 59.04 proved enough for her to claim silver - eclipsing Brown to become the youngest Olympic medallist in 85 years.

It comes as Katarina Johnson-Thompson withdrew from the women's heptathlon after suffering an injury to her right calf during the 200-metres.

The 28-year-old from Liverpool was a firm favourite for gold. This morning, she was fifth overall after three events and headed into the 200-metres in a strong position.

But she pulled up short and went down after the first bend. She refused treatment and completed the race with a slow jog but was disqualified because she left the lane.

There was speculation that Johnson-Thompson was suffering from an old Achilles injury in her left leg which she needed surgery for last December. However, this was denied by UK athletics.

Earlier this morning, Team GB's Ben Whittaker won a boxing silver medal in the light heavyweight final.

The 24-year-old from Wolverhampton lost to Cuba's Arlen Lopez in the gold medal 81kg final at Tokyo 2020.

He spoke of his disappointment, telling the BBC: "You don't win silver, you lose gold. I'm very disappointed with myself, I didn't perform well. Of course, [Lopez] is a class operator - two-time Olympic gold medallist now but I'm very disappointed. I feel like a failure.

"You're in this game to win gold, not win silver. I'm very upset, but this feeling will stick with me now. I don't want to feel like this again."

Nevertheless, Whittaker has been hailed as a hero at home in Wolverhampton with the mayor Greg Brackenridge promising the boxer "a day with the mayoral chains".

It follows an interview with the boxer in which he revealed a desire to become mayor of the city.

Mr Brackenridge said his phone has not stopped ringing since Whittaker's comment after his quarter-final fight.

He added: "I think he has earned a day with the mayoral chains."

And earlier this morning, fellow Briton Frazer Clarke, 29, secured a bronze medal after losing to Bakhodir Jalolov of Uzbekistan in the semi-finals of the men's super heavyweight boxing.

Sky Brown replaces Sarah Hardcastle as Britain's youngest summer Games medallist. The swimmer was aged 15 years and 113 days when she won silver and bronze in Los Angeles.

She also overtakes silver medal-winning figure skater Cecilia Colledge, who turned 15 just a couple of months before the 1936 Garmisch-Partenkirchen Games.

After her heats, Brown told the BBC: "That was insane. It is crazy. It is crazy to be here, and skating with all the girls has been really fun.

"Everyone has been ripping. It is awesome to be here. I didn't think about the scores. But I am really stoked on that score - very stoked.

Brown's achievement is all the more remarkable for the fractured skull and broken bones she suffered during a horrific fall in training last year.

The teenager posted a video clip of the fall on her Instagram account, which has approaching one million followers, along with the message: "I'm excited to come back even stronger and even tougher. My heart wants to go so hard right now."

CEO of Skateboard GB James Hope-Gill told Sky's Kay Burley: "One of the messages Sky wants to give is it doesn't matter how old you are, how big or small, girl or boy, go for your dreams. If you work hard and are committed you can achieve anything."

Brown, who was born in Miyazaki, Japan, to a Japanese mother and British father, competed at the US Open in 2016 at the age of eight, and first chose to compete for Great Britain in 2018.

She warmed up for the Games by winning gold in the prestigious X Games last month, although neither of her key Olympic challengers, Okamoto and Hiraki, were present.

Hiraki was first up of the major contenders in qualifying amid the hottest day of the Games so far, with the temperature tipping 32C with 90% humidity.

Elsewhere, Great Britain failed to retain their Olympic women's hockey title following defeat by the Netherlands in the semi-finals.

Reigning world champions the Netherlands secured a 5-1 victory and will go for gold on Friday, while GB will go for bronze.

Italy broke its own world record in beating Denmark to win the gold medal in men's team pursuit at the Tokyo Olympics.

And in athletics, the USA's Sydney McLaughlin broke her own world record to take gold in the women's 400m hurdles.

Britain's Katarina Johnson-Thompson sits fifth overall after three events in the heptathlon.
