Novak Djokovic completed the career Golden Masters in 2018. He achieved the feat by winning the Cincinnati Masters, the only ATP Masters 1000 tournament missing from his collection at that time.
In the 2018 Cincinnati final, Djokovic defeated Roger Federer 6–4, 6–4. The victory made him the first singles player to win all nine ATP Masters 1000 tournaments during a career. These events are among the most important competitions outside the four Grand Slam tournaments, covering major hard-court, clay-court, and indoor events around the world.
The achievement was especially notable because Djokovic had already won the other eight tournaments, including Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Shanghai, and Paris. His 2018 campaign also included Wimbledon and US Open titles. A common mix-up is confusing the 2018 completion with his second Career Golden Masters, which he completed after winning Cincinnati again in 2020.
