Agostina Hein has spent the latter half of 2025 knocking down national records all over the place. This weekend, she returned to her hometown of Buenos Aires for a victory lap, notching yet another Argentine benchmark.
The last hoorah for the 17-year-old Hein came in the 100 fly, somewhat of an off event. She rocked a 58.82 to knock down her own previous 59.36 mark. She is the lone woman from her country under 1:00.
The Argentine Open marks the 6th meet in the past 6 months that an Argentine record has fallen at the hands of Hein. This encompasses all but one of the meets that the teenager competed in during this time period (the José Finkel Trophy in October was the lone exception).

Apart from her 100 fly, Hein also got less than a tenth from two of her other national records. In the 200 IM, the albiceleste golden girl stopped the clock in 2:12.19 en route to victory. This is .07 away from the 2:12.12 mark she won the Junior Pan American Games with earlier in the season.
Next up, Hein took care of business in the 200 free with a 1:59.49, only .04 off her own 1:59.49 national mark.
Hein also won the 100 free (55.92), 400 IM (4:39.89), and 400 free (4:07.78).
14-year-old Laila Chain turned heads with a 1:02.55 100 back victory and scoring runner-up to Hein in 200 IM (2:19.21).
Macarena Ceballos, who broke her own breaststroke 50 breaststroke national record at 30 years old earlier this year, swept the discipline this weekend with 31.66/1:07.76/2:32.15 outings.
On the men’s side, notable performances included Lucas Ezequiel Alba’s 7:52.90 800 free, which fell just three tenths off the 12-year-old national record.
Junior Pan American Games gold medalist Ulises Cazau pulled off a speedy 23.74/52.30/2:04.05 butterfly triple.
