Czech eighth seed Karolina Pliskova saved eight break points to beat Ashleigh Barty in straight sets and reach the US Open quarter-finals.
The 2016 finalist broke in the opening game of the first set and the third game of the second to win 6-4 6-4.
But she withstood plenty of pressure from the Australian 18th seed.
Pliskova will face either American 23-time Grand Slam champion Serena Williams or unseeded Estonian Kaia Kanepi for a place in the last four.
“It was very tough even though the score looks easy,” Pliskova said. “I’m very happy to be through.”
