World number one Ashleigh Barty warmed up for the US Open by winning the Cincinnati Open with a straight-set victory over Jil Teichmann in the final.
Barty, 25, produced a polished performance to beat the 24-year-old Swiss wildcard 6-3 6-1.
The Australian managed eight aces and 28 winners as she cruised to another commanding victory.
It is a fifth title of the season for Barty, who is favourite to add the US Open title to her Wimbledon crown.
Teichmann, ranked 76th, reached the final by beating three top-12 players in four-time Grand Slam winner Naomi Osaka, fourth seed Karolina Pliskova and Olympic gold medallist Belinda Bencic, but was unable to contend with Barty's power and precision.
