Top-ranked Ash Barty won her fifth title of the season, taking eight of the last nine games from wild card Jil Teichmann for a 6-3, 6-1 victory in the Western & Southern Open final on Sunday.
Barty, who won her first Wimbledon title in July before getting upset in the first round at the Tokyo Olympics, now has plenty of momentum heading into the U.S. Open, which starts August 30 in New York.
Teichmann had a surprising run to the final, upsetting second-ranked Naomi Osaka, Olympic gold medalist Belinda Bencic and fourth-ranked Karolina Pliskova.
"This is where you belong," Barty said to Teichmann during the post-match ceremony. "You played exceptional tennis this week."
Barty, of Australia, broke Teichmann's serve to take a 5-3 lead in the first set, then won the next six games.
"It's been an awesome week," Barty said. "I felt like, each match, I got better and better in most parts of my game. I was just excited to get some matches under my belt in some tough conditions, and I think it put us in good stead going to New York."
In the second set, the Swiss player received medical attention on her heavily taped right foot during a changeover.
"I was very happy with my week," Teichmann said. "Obviously, today, I wanted to win, but Ash was just too good. I felt like I was there in the first set, but then she got a little break and it was gone. She played some good points. Then, in the second set, she stepped up her level. Ash was just too good."
Men's Olympic gold medalist Alexander Zverev had a relatively easy time in the Cincinnati men's final, winning the first four games en route to a 6-2, 6-3 victory over seventh-ranked Andrey Rublev.
