Karolina Pliskova powered her way into the U.S. Open women's quarterfinals, overwhelming American Jennifer Brady 6-1, 6-0 in just 47 minutes.
Two days after fighting off a match point to advance, the No. 1 seed won 22 of 24 points on her first serve and broke her unseeded opponent's serve six times.
The U.S. Open runner-up last year, Pliskova advanced to face either No. 20 CoCo Vandeweghe or unseeded Lucie Safarova.
She raced to a 4-0 lead and never let Brady get into the match in a much better performance than Saturday, when she struggled past No. 27 Zhang Shuai 3-6, 7-5, 6-4.
