It was her father, a coach and former player, who introduced Delfina Brea to padel in Buenos Aires, where she was born in December 1999. As a teenager she moved to Spain. In 2021 she won her first two tournaments with Tamara Icardo, the Santander and Valencia Opens. With Bea González she won 13 titles between 2023 and 2024. In August 2025, after winning the Tarragona P1 with Gemma Triay, she reached number 1 in the FIP ranking. She was the first Argentine player to do so since Cecilia Reiter in 2013. She plays on the right side. She plays with Bullpadel rackets and in 2026 competes with the Vertex 05 Woman, a diamond-shaped racket with a Carbontube frame and the Custom Weight system for adjusting weight and balance.
