Check back here for updates throughout the day.

Top-seeded Ash Barty still alive

No. 1 seed Ashleigh Barty is still alive in the Wimbledon draw despite all the top-10 seeds that fell around her this week.

Barty mowed down Katerina Siniakova, 6-3, 7-5, in a match that lasted 1:37 on Saturday to reach the fourth round.

The Australian Barty, 25, is the 2019 singles champion at the French Open. She has never made it out of the fourth round, reaching that spot in 2019 when she also made it to the quarterfinals of the Australian Open and fourth round of the US Open to bookend the year.

Barty will face Barbora Krejcikova, Siniakova's doubles partner, in the next round. Krejcikova is the reigning French Open champion who Barty called "an incredible challenge."

Federer rattled in third, comes back to advance

Roger Federer kept a late rally by Cameron Norrie at bay, advancing 6-4, 6-4, 5-7, 6-4.

Federer cruised in the early goings for his 104th Wimbledon victory, the most in the Open era. He had chances in the final game, but Norrie kept battling and fought for multiple break points and finally getting through to earn the set and stay in it.

Federer appeared ready to cruise into the second week in straight sets until Norrie came alive in that third and held serve to go up 6-5. Unforced errors by Federer helped Norrie take it, riding four set points and shaking the all-time great.

Norrie went up 30-0 and aced to 2-1, only to have Federer serve his way to a tie game. Norrie double-faulted, then errored to go down 40-0 and Federer mostly rode out the win from there.

It is Federer’s 69th career spot in a round of 16 at a Grand Slam, and his 18th at Wimbledon. Federer noted in the on-court interview after the match that it’s his last Grand Slam before turning 40 on Aug. 8. He's the oldest male player to reach the fourth round at Wimbledon since Ken Rosewall in 1975.

Federer will face No. 23 seed Lorenzo Sonego of Italy in the fourth round next week.

Nick Kyrgios retires with injury

Felix Auger-Aliassime is into the fourth round after Nick Kyrgios retired with injury following the second set, 2-6, 6-1. Kyrgios said ahead of the match that his body was in pain after playing for four consecutive days between singles and mixed doubles with Venus Williams.

The Australian started by match by forgetting his tennis shoes in the locker room and having them brought out to him.

He broke the 20-year-old Canadian early to go up, 3-1, and broke again for 5-2. He took a medal timeout and received a massage on the sidelines with what looked to be an abdominal issue.

He took the first set and the two were tied, 1-1. But Kyrgios, ranked 60th, began looking more in pain, grimacing as he consulted with trainers on the sideline and falling behind, 4-1. After Auger-Aliassime clinched the second set, 6-1, Kyrgios announced he wouldn't continue.

"It’s getting worse and worse – I can’t serve any more,” he told the trainer.

Auger-Aliassime is ranked 19th and making his second ever Wimbledon appearance. He made the third round in 2019. He's never made it past the fourth round of a Grand Slam, reaching that mark at the 2020 US Open and 2021 Australian Open.

Coco Gauff back in Wimbledon's fourth round

It was only two years ago that 15-year-old Coco Gauff became a household name with an astonishing run to the fourth round at Wimbledon.

Gauff, seeded 20th, is back in the fourth round again in her second appearance at the tournament. It wasn't the prettiest of wins, but she took down Kaja Juven, 6-3, 6-3, in early action on Saturday.

"Definitely coming in today, I wasn't as nervous as I was in my second round," Gauff said in the on-court interview.

Gauff took a 4-0 lead in the opening set, but fell down to 5-3 and 0-30 on her own serve against the 20-year-old Slovenian. She got out of it, and again pulled from down 0-1 in the second set to win. It took three tries to earn the match point.

She had five aces and won 71 percent of break points, but also had four double faults.

Gauff has yet to drop a set at Wimbledon this time around and will face Angelique Kerber in the next round on Monday, Kerber won the 2018 Wimbledon and advanced with a 2-6, 6-0, 6-1 win over Aliaksandra Sasanovich.

British teen breaks into second week

Emma Raducanu is on to the second week, joining Gauff as a teenager making an incredible run from lower seed to breakthrough star.

Raducanu, 18, is playing in her first Grand Slam and is the youngest British woman in the Open era to reach the fourth round by virtue of a 6-3, 7-5 win against veteran Sorana Cirstea. She came into the tournament on a wild-card entry and is ranked 338th in the world.

Raducanu won eight straight games for the 3-0 lead in the second set, but couldn't convert three straight break points in the next game and battled to finish. The game last 15 minutes before collecting three match points in the final game and winning on a Cirstea forehand in the net.

Raducanu will face Ajla Tomljanovic of Australia in the fourth round on Monday. Tomljanovic had never made it out of the second round at Wimbledon until this past week. She's never made it past the fourth round of a Grand Slam singles tournament.
