China's Zhang Shuai booked the third round ticket in her sixth trip to the Wimbledon women's singles after defeating Belgium's Yanina Wickmayer 6-3, 6-2 on Wednesday. Zhang will now take on 14th seed Caroline Wozniacki in her next match. 

Zhang admitted that Wozniacki is "too strong" for her as it's a big challenge to win against the former world number one.

Denmark's Caroline Wozniacki powered past unseeded Russian Veronika Kudermetova 7-6(5) 6-3 to set up a third-round meeting with Zhang.

Wozniacki is tied at 1-1 in her head-to-head record against Zhang, with the Chinese player triumphing in three sets in their most recent meeting at 2016 Indian Wells.

Fairytale

American sensation Coco Gauff continued her magical Wimbledon debut on Wednesday when she became the youngest player since 1991 to reach the third round.

Gauff, just 15 and who had to come through qualifying, had already stunned five-time champion Venus Williams in the first round.

She showed that was no fluke as the world number 313 defeated 2017 semi-finalist Magdalena Rybarikova of Slovakia 6-3, 6-3 under the new Court One roof.

The American schoolgirl is the youngest player in the last 32 since Jennifer Capriati, also 15, went all the way to the semifinals 28 years ago.

"I played well especially on the pressure points," said Gauff.

"I'm just still shocked that I'm even here. I think I can beat anyone. If I don't think I can win the match then I won't even step on the court."

Djokovic through, Wawrinka out

Four-time champion and world number one Djokovic made the last 32 for the 11th successive year as he eased past Denis Kudla of the United States, 6-3, 6-2, 6-2. 

"I'm pleased with my game overall. There were some moments in the match where maybe I could have done better," said the defending champion.

"But overall, a solid performance."

Djokovic goes on to face Hubert Hurkacz for a place in the last 16 having defeated the Pole in straight sets in the first round at Roland Garros in May.

Two-time quarter-finalist Wawrinka, 34, was beaten 7-5, 3-6, 4-6, 6-4, 8-6 by his American opponent, the tallest man in the sport and 13 years his junior.

Opelka fired 23 aces and 59 winners and goes on to face 2016 runner-up Milos Raonic of Canada.

Opelka will be appearing in the third round at a Slam for the first time having never won a grass court match in his career prior to coming to Wimbledon.

Wawrinka won heartfelt applause for giving a line judge a warm embrace after accidentally colliding with her as he sprinted to hit a backhand.

"I was a bit too far to return a serve. I think I went against her, so I was sure she had some pain and was not happy, so I gave her a little hug," said the genial Swiss.
