NEW YORK -- Karolina Pliskova dominated with her serve to roll past 18-year-old Ana Konjuh and into the U.S. Open semifinals.
The 10th-seeded Pliskova won 6-2, 6-2 in just 57 minutes Wednesday, losing only one point on her serve in the first set. She'll face No. 1 Serena Williams or fifth-seeded Simona Halep on Thursday.
The 24-year-old Czech came into the U.S. Open with the distinction of being the only woman in the top 20 to never reach a Grand Slam round of 16.
