MELBOURNE, Australia (AP) — Jessica Pegula cruised into the fourth round of the Australian Open on Friday with a 6-0, 6-2 win over Marta Kostyuk.
The third-seeded Pegula, a quarterfinalist the past two years at Melbourne Park, needed 65 minutes for victory as the American set up a round-of-16 match against Barbora Krejcikova, the 2021 French Open champion.
"I thought I just didn't give away a lot of free points," Pegula said. "I was playing aggressive when I had to but also smart. Happy to be through to the next round."
Last year's finalist Danielle Collins of the U.S. was beaten 6-2, 5-7, 6-2 by Wimbledon champion Elena Rybakina. Coco Gauff was playing Bernarda Pera later on Friday.
Krejcikova was the first player to advance to the fourth round after a 6-2, 6-3 win over Anhelina Kalinina to open play Friday at Rod Laver Arena.
The 20th-seeded Czech player won the first five games of the match and dominated her Ukrainian opponent. Krejcikova has not dropped a set in three matches.
In men's play, Stefanos Tsitsipas will take on Jannik Sinner in the fourth round.
Third-seeded Tsitsipas saved a set point in the second set but beat Tallon Griekspoor 6-2, 7-6 (5), 6-3 to reach the last 16 at Melbourne Park for the third time in four years.
