Coco Gauff is back into the second week of Wimbledon.
The 17-year-old American matched her breakout result from 2019 by reaching the fourth round with a 6-3, 6-3 win over Kaja Juvan on Centre Court. Gauff finished with 21 winners and broke her opponent five times.
Gauff will face former Wimbledon champion Angelique Kerber on Monday.
Kerber turned her third-round match around completely after a rain delay to beat Aliaksandra Sasnovich 2-6, 6-0, 6-1.
Kerber trailed 5-1 in the first set when play was halted for about 90 minutes but dominated her Belarusian opponent when the match resumed.
Kerber is the only former women's champion left in the draw. Sasnovich advanced from the first round when Serena Williams had to retire with an injury in the first set.
She will face French Open champion Barbora Krejcikova on Monday, a matchup she called "an incredible challenge."
Barty won the French Open in 2019, the same year she reached the fourth round at Wimbledon.
Also Saturday, Emma Raducanu became the youngest British woman to reach the fourth round of Wimbledon in the Open era.
The 18-year-old Raducanu converted her third match point to beat veteran Sorana Cirstea 6-3, 7-5 on No. 1 Court. She is playing in her first Grand Slam tournament.
Raducanu won eight straight games to take a 3-0 lead in the second set, then struggled to put away Cirstea. She failed to convert three straight break points in the next game, then was broken and missed another five break points at 4-3.
She needed another three attempts in the final game before Cirstea netted a forehand to end the match.
