British number one Johanna Konta continued her US Open preparation with a first-round win over Germany's Laura Siegemund at the Connecticut Open.
Konta, now ranked 46th, won 6-2 7-5 against the world number 146.
The Briton lost four points on serve in the opening set but had to dig deeper in the second before breaking to lead 6-5 and serving out the win.
She is the only British woman with direct entry into main draw of the US Open, which begins on 27 August.
Konta, 27, was the seventh seed at Flushing Meadows last year, but lost to unseeded Serb Aleksandra Krunic in the first round and has dropped down the rankings since.
