Coco Gauff beat Karolina Muchova 6-3, 6-4 to win the biggest title of her young career at the Cincinnati Open on Sunday and extend her outstanding run of form on North American hard courts ahead of the US Open.
The American teenager, seeded seventh, broke the Czech player three times in the opening set and confidently served out the opener to love in her first WTA 1000 final appearance.
Muchova, who will enter into the top 10 for the first time thanks to her run to the final, was too inconsistent on a hot day in Ohio, badly missing a backhand up the line to hand Gauff the break and a 3-2 second-set lead.
Gauff had some trouble getting over the finish line, failing to convert three match point opportunities while serving at 5-2 thanks to some tentative groundstrokes.
But on her next chance to serve for the title, she did not falter, with Muchova’s return landing wide as Gauff jumped up and down in jubilation.
Gauff, who improved her record to 11-1 since falling in the first round of Wimbledon last month, looks poised to be a real threat when she arrives in New York for the final major of the year, the US Open, which runs Aug. 28 through Sept. 10.
She will be seeded sixth at Flushing Meadows after winning the title in Washington, D.C., making the quarters of the Canadian Open and winning the title on Sunday in a tournament in which she beat world No. 1 and US Open defending champion Iga Swiatek in the semis.
