Coco Gauff claimed her third tournament win of the season with victory over Karolina Muchova in the Southern and Western Open final.
The seventh-seeded American teenager produced a strong performance to see off the world number 17 6-3 6-4 in one hour and 56 minutes in Cincinnati.
The 19-year-old's victory will ensure she climbs to number six in the WTA rankings on Monday while Czech Muchova can console herself with a spot in the top 10.
Muchova showed her battling qualities in the second set as she saved three match points when trailing 5-2 and pulled one break back, but Gauff was not to be denied.
