 Roger Federer moved into the fourth round of a Grand Slam tournament for the 69th time on Saturday, overcoming a raucous home crowd and the last British man in the draw Cameron Norrie in an entertaining 6-4, 6-4, 5-7, 6-4 win at Wimbledon.

Federer kept his dream alive of a record-extending ninth singles title.

On the women's side, Australia's world No.1 Ashleigh Barty looked a bit more fluent after two inconsistent performances in moving into the last 16.  

The 25-year-old's 6-3, 7-5 win over Katerina Siniakova reassured her fans she can win the title on the 50th anniversary of fellow indigenous Australian Evonne Goolagong Cawley's first Wimbledon crown.

Victory pitches her into a fourth round clash with French Open champion Barbora Krejcikova.

Krejcikova has been under the radar but battled through to the Last 16 beating Anastasija Sevastova of Latvia 7-6 (7-5), 3-6, 7-5.

Federer said this Wimbledon held special significance for him.

"I hope there is a little bit more left in me as this one is special for it is the last slam before I hit the big 40," said Federer, the third-oldest man to reach the Last 16 in the Open era.

Norrie follows two-time champion Andy Murray and British No.1 Dan Evans in exiting in the third round.

Federer's half of the draw looks more treacherous than defending champion Novak Djokovic's with two of the younger generation - Russia's Daniil Medvedev and Germany's Alexander Zverev - potentially lurking further down the line.

Second seed Medvedev showed his mettle as for the first time in his career he came from two sets down to beat 2017 Wimbledon finalist Marin Cilic.

Zverev ended big-serving Taylor Fritz's impressive campaign - 6-7 (3/7), 6-4, 6-3, 7-6 (7/4) - given he exited the French Open in a wheelchair due to a knee injury.

Barty remained poker-faced even when she served for the match and once again her serve was found wanting as Siniakova broke her.

However, she made no mistake the second time she served for it and did a gentle fist pump to celebrate it.

Should Barty reach the quarterfinals for the first time, she will face a tough rival in either Coco Gauff or 2018 champion Angelique Kerber.
