For a fifth time in her career, Madison Keys is through to the fourth round at Wimbledon.

The 12th-seeded American eased to a 6-4, 6-3 win over No.18 seed Marta Kostyuk at the All England Club on Friday to book a date with No.7 seed and French Open finalist Jasmine Paolini in the last 16.

Keys' win added to a strong early morning for American women, as Emma Navarro advanced to her first fourth round at Wimbledon with a 2-6, 6-3, 6-4 win over Bad Homburg champion Diana Shnaider, snapping the 20-year-old's eight-match grass-court winning streak. Shnaider had beaten Navarro in two prior three-setters this year. No.2 seed Coco Gauff made it a perfect 3-0 for U.S. women in the bottom half when she beat British qualifier Sonay Kartal later.

Keys is now 2-0 against Kostyuk in their careers, and both meetings have come in the third round of Wimbledon. Last year, Keys won 6-4, 6-1, and she was almost as comprehensive in the reprise. Keys lost serve just once -- in her first service game -- and never again faced break point in 1 hour of 12 minutes of play on Court 12.

"Going into it I knew that she can play an incredibly high level. So you always have to be aware of that, and you have to expect her to play her best," Keys said afterwards.

"I don't think she would think that she played her absolute best today, but I also think that I kept trying from the start to put a lot of pressure on her to try to keep some of the momentum that I kind of got. I think I played her here last year, so kind of knew how she played on grass, which is always helpful.

"But I think I knew walking out there that I was going to have to play a good level because she's a great player, and her level can be incredibly high. I think knowing that, I just had to really kind of from the very start be really solid and just kind of see how things played out."

More key numbers from Keys' win included: 

5: Keys is now through to the fourth round at Wimbledon for a fifth time in 10 career main draws at the tournament.

7: The 29-year-old American now owns 64 wins over Top 20 places, seven of which have come this year. Keys is 7-3 against other Top 20 players in 2024.
