Canadian Dante Leon goes after submission grappling world title in Bangkok
The 29-year-old from Harrow, Ont., who now calls Toledo, Ohio, home, faces American champion Tye Ruotolo for the One Championship welterweight submission grappling title in the co-main event of One Fight Night 31 at Lumpinee Stadium in Bangkok.
'This is the most important match of my career … Achieving that title, achieving that status would definitely be a life-changing thing,' Leon said in an interview.
The Muay Thai main event is an all-Thailand affair pitting Kongthoranee Sor Sommai against former One bantamweight champion Nong-O Hama.
Leon and Ruotolo have met twice before, with Leon winning a decision in 2020 and Ruotolo winning by submission in the 2021 rematch.
'I think any insight from those matches should be kind of taken with a grain of salt,' said Leon. 'There's been quite a bit of time between the matches.'
Both men have distinguished grappling records.
The 22-year-old Ruotolo took up BJJ at the age of three with twin brother Kade, who holds One's lightweight (170-pound) submission grappling title. In 2019, 16-year-old Tye became the youngest athlete to make it to the semifinals of the prestigious ADCC (Abu Dhabi Combat Club) World Championship.
In 2022, he became the youngest-ever IBJJF (International Brazilian Jiu-Jitsu Federation) world champion.
Leon is a two-time IBJJF no-gi world champion and was named Grappling Insider's Male Grappler of the Year in 2023. Last year at the ADCC World Championships, he defeated ADCC world champions Mica Galvao and Giancarlo Bodoni en route to bronze in the absolute (open) division.
Leon won his One Championship debut on Dec. 6, making short work of Brazilian Bruno (Puccibull) Pucci on the undercard of One Fight Night 26: Lee vs. Rasulov. He earned a US$50,000 bonus for his performance.
He then defeated Norway's Tommy Langaker via decision on Jan. 10, also in Bangkok. Leon has not competed since, focusing instead on preparing for Ruotolo.
Ruotolo, who is coming off a knee injury that has sidelined him since July, has won all seven previous One Championship bouts. His bouts last an average of two minutes and one second.
He claimed the 185-pound title in November 2023, winning a unanimous decision over Russia's Magomed Abdulkadirov. Ruotolo has defended the championship twice, submitting Australian Izaak Michell in April 2024 and earning a decision over South Africa's Jozef Chen in July.
Ruotolo calls Leon a threat 'in every department.'
One Championship submission grappling bouts consist of a single 10-minute round with victory achieved by a submission, verbal tapout, stoppage initiated by either the referee (due to imminent danger) or an athlete's cornerman stoppage.
The judges decide the outcome if it goes the distance.
In order to make prime time in North America, the card starts at 8 a.m. local time in Thailand with Leon expecting to compete around 11 a.m. He says that is not an issue given he normally trains around that time.
Born in Harrow in southwestern Ontario, Leon grew up playing hockey but switched to BJJ at 12 years old at the behest of his mother after learning he wanted to spend less time on the ice.
Leon turned down golf and piano lessons before his father suggested jiu-jitsu.
His BJJ training eventually took him to Toledo where he now has his two gyms.
'Each day that I get to do it, each day that I get to wake up and train, prepare for competition, teach my students is a blessing,' he said of jiu-jitsu. 'I really do enjoy it.'

But he acknowledges it's a sport that takes its toll.
'Jiu-jitsu is not something that's great for your body health-wise,' he said. 'Especially at a high level when you train a lot, I think it's something that can really break your body down … My training has a lot of layers. There's a lot to do with the jiu-jitsu side and the wrestling, and the preparation for my skill development.
'And then there's also a lot of strength and conditioning and plyometric work that can kind of fill the gaps and strengthen me so that I can do jiu-jitsu more frequently and do it for a longer time.'

It's Ledecky vs. McIntosh in the 800 freestyle, the centerpiece of the world championships
SINGAPORE (AP) — It's Katie Ledecky against Summer McIntosh in the final of the 800-meter freestyle, probably the most anticipated race at the swimming world championships in Singapore. The race is one of six finals on Saturday, but it overshadows everything else on Day 7. The championships wrap up on Sunday. Ledecky of the United States holds the world record (8 minutes, 04.12 seconds) set earlier this year. The 28-year-old American has dominated the distance for a decade and has already won gold in the 1,500 in Singapore. She also has a bronze in the 400. Ledecky, 28, has won nine Olympic gold medals — the most decorated female in history — and her first gold was in 2012 in the London Olympics in the 800. McIntosh is an 18-year-old Canadian. She's already won three golds in Singapore and she swam just a second off Ledecky's time earlier this year. If anyone is to dethrone Ledecky, it's McIntosh. This would be McIntosh's fourth gold as she goes for five individual golds in the worlds, a feat only achieved the legendary American swimmer Michael Phelps. The other five finals are: the women's 50 butterfly; the men's 50 free; the women's 200 backstroke; the men's 100 butterfly; and mixed 4×100 freestyle relay. The Americans and Australians have each won five gold medals through six days. The Americans lead in overall medals with 20, although their performance has been lackluster and slowed after much of the team came down with a case of 'acute gastroenteritis' in training camp in Thailand. __ AP sports:

Ex-Olympic champ Rowdy Gaines calls for changes at USA Swimming as team struggles in Singapore
SINGAPORE (AP) — Rowdy Gaines, a three-time Olympic gold medalist, minces few words when he broadcasts swimming for the American network NBC. And he didn't hold back in an interview with The Associated Press over the shaky state of American swimming. He's calling for big-time changes as the Americans struggle at the world championships in Singapore. The American team isn't winning as much as expected or dominating, it's battling a case of 'acute gastroenteritis' picked up at training camp in Thailand before arriving in Singapore, and the governing body — USA Swimming — has been without a CEO for a year. Gaines called the body 'rudderless.' 'Can you imagine any corporation going for a year without a CEO?' Gaines asked. Underwhelming Americans The Americans were also underwhelming a year ago at the Paris Olympics. They led the medal table, but won only eight gold medals, the lowest total since the 1988 Seoul Olympics. 'We're far from killing it,' said Gaines in a telephone interview from the United States. 'It's a major struggle and we can't hide our heads in the sand and say this is just a blip.' Gaines said he's been texting frequently with Greg Meehan, the national team director who was appointed four months ago. Meehan is also the head coach in Singapore. The American haven't said how many swimmers have fallen ill, but in an interview Meehan said 'the overwhelming majority of the team has gone through something' at the championship.' 'Greg and I have been going back and forth in a very good way, very positive,' Gaines said. He called Meehan a good choice and said he's had too little time to turn things around. Gaines also pointed out that the focus is the 2028 Olympics in Los Angeles. These world championships, less so. 'I think he's (Meehan) going to be great,' Gaines said. 'He's got that calm reserve. He had great success at Stanford. He's coached some of the best swimmers ever. I think he's a good choice, he's just walking into a bit of a landmine.' Thailand training camp Like many, Gaines questioned why the Americans picked Thailand as a training camp site and noted that global swimming now has dozens of countries that can beat the Americans, and many of their elite athletes train in the States. Those include the two stars in Singapore: Frenchman Léon Marchand and Canadian Summer McIntosh. Marchand trains at the University of Texas at Austin, and McIntosh will be there this fall and join Bob Bowman's training group. Bowman is, of course, the former coach of American swimming legend Michael Phelps. 'You can blame it on the illness, you can blame it on the inexperience — most of these kids have never been in this situation — and you can blame it on logistics,' Gaines said. 'Thailand doesn't make sense to me in the first place.' He also put some blame on what he called the 'state of today's athletes.' 'I think in some cases there's an entitlement for a lot of these kids, they feel like — 'I should be in the finals of the world championships. And I can still do the peripheral stuff and not worry about making it all the way'.' 'I think there needs to be a more focused attitude on the task at hand,' he added. Post-Olympic blahs Gaines also noted that many swimmers struggle the year after the Olympics. They just finished a four-year cycle, so where is the motivation to start over again? 'It just beats you up because mentally and physically you are focused on four straight years, and the post-Olympic year can beat some people up. The post-Olympics is a real thing for all athletes whether you're from China or the United States.' On the positive side, he talked up the future of 10 to 15 young American male swimmers including Luca Urlando, the winner of the 200-butterfly and the only American man to win gold over the first five days. The championships end Sunday. 'The women are already very good,' Gaines added. Gaines said much of the problem is that USA Swimming has gone for a year without a leader. Tim Hinchey resigned as the CEO a year ago. He was replaced by Chrissi Rawak, who stepped down after just a few days. 'I do think changes need to be made, there needs to be a complete reset,' Gaines said 'But I don't think the sky is falling. But there needs to be some great leadership. Whoever they hire as CEO needs to be the leader that is sorely needed.' __ AP sports:

The last Canadian falls in Toronto, with Gabriel Diallo finding his game on the fritz
In 2021, after losing in the third round at Wimbledon and further free-falling out of the top 40, Taylor Fritz was on his way back to the hotel with his girlfriend when he grabbed her phone and banged off a note to himself: 'No one in the world is playing more below their potential than you. You're f—-ing good but snap out of it man.'' Fast forward four years and a game rebuilt around knee surgery and the 27-year-old is No. 4 in the world in men's tennis. Though no American man has won a singles title at the All England Lawn and Tennis Club since Pete Sampras a quarter-century ago, Fritz made it to the semifinal last month, where defending champion Carlos Alcaraz knocked him out in four sets.
