Three of the four singles finalists at the 2026 Cincinnati Open were American.
The women’s final was entirely American, with Coco Gauff defeating Jessica Pegula. The men’s final included American Frances Tiafoe, who faced France’s Arthur Fils. Together, those four finalists meant that three represented the United States.
This was a notable result for American tennis because both singles finals included U.S. players. Gauff won the women’s title, while Tiafoe finished runner-up in the men’s event.
The tournament’s official review highlighted the figure as one of the major stories of the 2026 edition. It also placed the result in the context of a large combined field, with 322 matches played across the men’s and women’s competitions.
