Which tournament gave Djokovic his first ATP title?

Djokovic won his first ATP title at Amersfoort in 2006, at the Dutch Open on outdoor clay. The 19-year-old Serbian defeated Nicolás Massú 7–6(5), 6–4 in the final on 23 July.

The victory was a major early milestone. Djokovic entered the tournament as the third seed and did not drop a set in the main draw. He defeated Guillermo Coria in the semifinal after Coria retired, then held his nerve against Massú in a tight final-set-opening tiebreak before breaking away in the second set.

Amersfoort is often confused with Umag, another 2006 clay-court tournament won by Stan Wawrinka. Djokovic’s second ATP title came later that year at the Moselle Open in Metz, where he defeated Jürgen Melzer.

The breakthrough helped Djokovic rise from world No. 36 to No. 28 and eventually finish 2006 at No. 16. It came only weeks after his first Grand Slam quarterfinal at Roland Garros and marked the beginning of his climb into the sport’s elite.
