One year later, Marín suffered another first round defeat at the World Archery Championships' women's individual event in June, losing to Elizabeth Bidaure of the Philippines. She fared little better in the women's team event, the trio of Marín, Elia Canales, and Mónica Galisteo defeating Vietnam in the opening round but faced what "Marca" called the "theoretically unbeatable" South Korea in the second round. Later that month at the 2019 European Games in Minsk, Marín finished thirteenth in the ranking round and was paired with Denmark's Maja Jager in her first elimination match. In a repeat of their semi-final at the 2015 European Games, Jager proved stronger and defeated Marín by six set points to four, Marín failing to maintain her performance from the ranking round.
