2025 Brazilian World Championship Trials: Sam Short & Guilherme Costa Nail 400 Free

2025 MARIA LENK TROPHY/BRAZILIAN SWIMMING CHAMPIONSHIPS

Day one of the 2025 Maria Lenk Trophy/Brazilian Swimming Championships began with a head-turning performance by visiting Australian swimmer Sam Short in the men’s 400m freestyle.

After posting an impressive time of 3:47.84 in this morning’s heats, the Aussie Olympic finalist punched a result of 3:44.16 to handily grab the gold.

21-year-old Short beat the field by a comfortable margin, with Guilherme Costa next to the wall in 3:45.35 followed by Stephan Steverink who rounded out the podium in 3:47.21.

Short’s result this evening was within range of the Aussie’s season-best, a time of 3:43.84 from the Pro Swim Series in Sacramento earlier this month to rank #3 in the world.

Costa and Short finished alongside one another in this event at the 2024 Olympic Games. Short clocked a time of 3:42.64 to place 4th while Costa claimed 5th place in 3:42.76, a new national record.

While Short will need to repeat this caliber of performance at the Australian World Trials in June, Costa and Steverink accomplished their mission of qualifying for this summer’s World Championships with their outings here. They both cleared the World Aquatics ‘A’ standard of 3:48.15 needed for Singapore, with Costa now ranking 5th in the world.

The Brazilian women also found success in the 400m free with day one’s final seeing two athletes qualify for the World Championships.

Maria Fernanda Costa, the reigning Brazilian national record holder in this event, produced a gold medal-worthy time of 4:06.30.

Although the 22-year-old led wire-to-wire, she had to fight hard to keep Gabrielle Roncatto behind her. Roncatto was with her stroke-for-stroke, ultimately touching in a speedy 4:06.53 to finish only .23 later.

Aline Da Silva Rodrigues rounded out the podium in 4:11.26.

Both Costa and Roncatto dipped under the ‘A’ standard of 4:10.23 by a large margin, solidifying their spots on the Brazilian Worlds roster. The former now represents the fourth-fastest woman on the planet, while the latter checks in as the sixth-swiftest.

Kayky Mota came painstakingly close to qualifying for Worlds en route to taking the men’s 100m fly event.

Mota, who turned 26 years of age on April 22nd, stopped the clock at a time of 51.81, comprised of a 24.22 opener and a back half of 27.59.

That was within range of the former University of Tennessee’s lifetime best of 51.41 notched during the semi-finals at the 2023 World Championships but fell short of the ‘A’ standard of 51.77 by only .04.

Also getting close to the QT was runner-up Gui Caribe. Caribe earned silver in 51.86 (24.55/27.31), establishing a new lifetime best in the process.

Bronze went to Lucio Flavio Paula who registered 52.52.

Additional Notes

  • University of Michigan Wolverine Stephanie Balduccini struck gold in the women’s 100m fly, posting a time of 58.94 as the sole swimmer to delve under the 59-second barrier. Balduccini split 27.95/30.99 to get the job done ahead of Beatriz Bezerra who grabbed silver in 59.64. Gabriela Albiero, formerly from the University of Louisville, also landed on the podium in 59.92 for bronze. The women were chasing an ‘A’ standard of 58.33, although Balduccini’s result destroyed her previous career-quickest mark of 59.27 from the 2022 edition of this competition. She’s now her nation’s 6th-best performer of all time.
  • Gabrielle Assis Da Silva got to the wall first in the women’s 100m breast, putting up a time of 1:08.62 to beat the pack by over a second. Her outing sliced .25 off her previous PB of 1:08.87 logged last year.
  • The men’s 100m breast saw Caio Pumputis turn in a time of 1:01.13 for gold, although he needed to be at least as rapid as 59.75 to make the World Championships standard.

I need to see more from short in order to be concinced he has a chance against Martens, I predict Martens goes 3:39.3 at worlds and right now I can’t see short breaking 3:41, still a very solid time but I doubt it will win.

You need to see more swimming in general. Germans usually go way slower at big meets than at their trials. The stockholm open is also a traditionally a super fast meet. No one will break 3.40 at worlds.

What happened with Brazilian breaststroke? Once regarded as top talented world champions with Felipe Lima, Felipe França, João Jr, Henrique Barbosa..now they can’t even break 1:01 to win nationals!
