This represents a minor technical refinement but remains below Cesar Cielo's national record of 20.51 set in 2026. Gui Caribe currently ranks 13th all-time in short-course 50m freestyle and is Brazil's second-fastest performer. Leonardo Alcântara, the 21-year-old athlete training at the University of Alabama, created excitement by breaking the South American record in the 800m freestyle with 7:37.47, an improvement of nearly 14 seconds from 7:51.81. Alcântara is the first South American swimmer under 7:40 in this event, surpassing Guilherme Costa's previous record of 7:41.23 from 2026. All results were achieved in 25m short-course meters pools with no reported rule violations under World Aquatics regulations.
