The Cincinnati tournament has come a long way from its humble roots, first played at the Avondale Athletic Club more than a century ago, to the grand-scale ATP Masters 1000 event held at the Lindner Family Tennis Center today. Past champions include such all-time greats as Ivan Lendl, Stefan Edberg, Pete Sampras, Rafael Nadal, Roger Federer and Novak Djokovic. In 2018, Djokovic triumphed in Cincinnati to become the first player to win all nine ATP Masters 1000 crowns and complete the Career Golden Masters.
