She won her sixth consecutive ITF Women's Circuit title at the 2023 Caldas da Rainha Ladies Open, defeating Léolia Jeanjean in the final in straight sets, and set the new Croatian record for the youngest women's player to win six professional singles titles before turning 18.
Having been given a wildcard entry, Marčinko was runner-up at the WTA 125 2024 Montreux Nestlé Open, losing to seventh seed Irina-Camelia Begu in the final in three sets.
