Novak Djokovic defeated Roger Federer in the 2018 Cincinnati final to complete the Career Golden Masters.
Djokovic won the final 6–4, 6–4, earning his first Cincinnati Masters title. That victory made him the first men’s singles player to win every one of the nine ATP Masters 1000 tournaments during his career.
The achievement was especially significant because Cincinnati had been the one Masters 1000 event Djokovic had never won. He had previously reached several finals there, including losses to Federer, but finally completed the collection in their 2018 championship match.
The result is sometimes confused with Djokovic’s 2013 Monte-Carlo victory over Rafael Nadal, which gave him titles at eight of the nine Masters events. The Cincinnati win five years later supplied the missing ninth title. Federer was the runner-up, not Stan Wawrinka, Grigor Dimitrov or Marin Čilić.
