At which tournament did Rafael Nadal win his first ATP singles title?

Rafael Nadal won his first ATP singles title at the Prokom Open.

The event was the 2004 Idea Prokom Open, played on outdoor clay courts in Sopot, Poland, from 9 to 15 August 2004. Nadal was 18 years old and defeated Argentina’s José Acasuso 6–3, 6–4 in the final. That victory made him an ATP Tour singles champion for the first time.

The tournament was later known as the Warsaw Open, but “Prokom Open” is the historically correct name for the 2004 edition. This naming history can cause confusion, especially because tournaments often change sponsors, locations, or branding over time. The event was part of the 2004 ATP Tour’s International Series.

Nadal’s first ATP title came before his breakthrough at Roland-Garros in 2005, when he won the French Open at age 19. The Prokom victory therefore marks an important early step rather than one of his later, more famous clay-court milestones. The Swedish Open, China Open, and Qatar Open were not the tournament where he claimed his first ATP singles crown.
