Daniel Merida Aguilar

Daniel Merida Aguilar is the Madrid-born right-hander who arrived on the main tour the hard way — junior pedigree first, then a long apprenticeship on the ITF and Challenger circuit. He reached the boys' singles quarterfinal at the 2021 French Open, where he lost to 13th seed and eventual champion Luca Van Assche. He turned pro that same year and spent his early twenties banking points one week at a time rather than skipping the queue.

The game is clay-first and built on grind, in the classic Spanish mold carried onto faster surfaces. Over his career at ATP level, he holds a record of 5-1 on clay against 0-1 on hard. The serve is functional rather than a weapon — he averages roughly 2.5 aces per match — so the profit comes from the return, extended rallies and a heavy court coverage that wears opponents down. The vulnerability is the second serve, where he wins under half his points and holds at around a 75% clip.

The breakthrough came in 2025-26. He won his first Challenger title at Pozoblanco, beating Sun Fajing in the final, then a second in Tenerife over Francesco Maestrelli. The defining run was Bucharest: he qualified, then upset second seed Adrian Mannarino and third seed Fábián Marozsán for his first top-100 wins before losing to Mariano Navone in the final. He followed it by qualifying for his home Madrid Open, beating Marco Trungelliti in the first round and 26th seed Corentin Moutet in the second.

That climb pushed him to a career-high of No. 82, reached on 8 June 2026. The most recent test was the slam stage: at the French Open he ran into Ben Shelton, who beat him 6-3, 6-3, 6-4 on May 25. The beat now is consolidation — turning a top-100 debut into a top-100 residency.
