Argentina’s Agostina Hein has been the biggest standout in South American swimming in recent times. On the second day of finals at the Pan Pacific Championships in Irvine, she finished third in the women’s 400 IM, behind world-record holder Summer McIntosh of Canada and Australia’s Jenna Forrester. Her time of 4:32.54 set a new South American record in the event, improving on her own 4:34.34 from the 2025 World Junior Championships, where she won gold.
She has been absolutely on fire in 2026, breaking South American records in the 800 freestyle and 200 IM, as well as Argentine records in the 200 and 400 freestyle and 100 butterfly. In the 400 freestyle, she came just 0.13 seconds short of the South American record held by Brazilian Olympic finalist Maria Fernanda Costa.
At just 18 years old, she is undoubtedly the biggest prospect in South American swimming in recent years. She made her international breakthrough at the 2023 World Junior Championships, when, at just 15 years old and competing against swimmers up to three years older, she won the bronze medal in the 800 freestyle.
When she broke her first South American record, in the 400 IM at the 2025 World Junior Championships, she surpassed the long-standing record of compatriot Georgina Bardach, who had set the previous mark of 4:37.51 en route to the bronze medal at the 2004 Olympic Games in Athens.
At the time, Hein’s performance attracted significant attention because it would have been fast enough to win the bronze medal at the 2024 Olympic Games. Her 4:32.54 at the Pan Pacific Championships goes even further: it would have earned her the silver medal in Paris two years ago.
The expectations surrounding the swimmer are justified. Historically, South America has won far more Olympic swimming medals with men than with women in pool swimming. There have been 19 men’s medals (15 for Brazil, 2 for Suriname, 1 for Argentina and 1 for Venezuela), compared with just two women’s medals — both won by Argentine swimmers: Jeanette Campbell’s silver in the 100 freestyle in 1936 and Georgina Bardach’s bronze in the 400 IM in 2004.
Hein currently ranks 21st all-time in the 400 IM. The highest-ranked active South American swimmer in the all-time rankings is Brazil’s Etiene Medeiros, who is 14th in the 50 backstroke. Medeiros was the 2017 world champion, spent more than three years retired, and returned to competition this year with the goal of making the 2028 Olympic team. She won the Brazilian Nationals in May in 28.43, still 1.29 seconds off her personal best. She still has a long way to go if she is to seriously contend for an Olympic medal two years from now.
Next is Brazil’s Maria Fernanda Costa in the 400 freestyle, ranked 26th all-time, which is relatively close to Hein’s position. However, Costa’s 4:02.86 remains some distance from the sub-four-minute times needed to realistically contend for an Olympic medal in an event featuring swimmers such as Summer McIntosh, Katie Ledecky, Lani Pallister and Erika Fairweather. Hein’s 4:32.54, as mentioned above, would have put her on the podium at both the 2024 Olympics and the 2025 World Championships. In 2025, she finished sixth in the world rankings, and she currently sits fourth in 2026, behind Summer McIntosh, Yu Zidi and Jenna Forrester.
Hein has worked with her coach, Sebastian Moreno, for years, and her progression leaves little doubt: she is the leading female swimmer in South America today and the one with the greatest potential for international success.
