be on Cori “Coco” Gauff — the 15-year-old sensation who has taken this grand slam by storm — as she continues her remarkable fortnight. But she faces one of the pre-tournament favorites in Simona Halep, a former world No.1.
The “Big Three” in the men’s game, Novak Djokovic, Rafael Nadal and Roger Federer, all face tricky ties but it’s the Swiss who has arguably the toughest day.
Eight-time champion Federer is up against talented Italian youngster Matteo Berrettini, seeded 17th at the All England Club, who has already overcome the tests of Diego Schwartzman and Marcos Baghdatis.
Third seed Nadal opens proceedings on Centre Court against Portugal’s Joao Sousa, while defending champion Djokovic plays French 21-year-old Ugo Humbert in the third match on No.1 Court.
Home favorite Johanna Konta — the only Briton remaining in the draw — faces No. 3 seed and former Wimbledon champion Petra Kvitova.
Riske, whose previous best grand slam result was a fourth-round defeat at the 2013 US Open, said she was “proud” of herself for reaching the quarter finals for the first time.
“I’ve been ready to battle every day that I go out there and that’s really shown in all my matches,” she told BBC Sport.
“I couldn’t begin to say what it means to me. To have overcome the matches the way I have is what I’m most excited about. Getting to the quarter-finals is amazing but what’s most exciting for me is the way I’ve been fighting.
“The grass definitely brings out the best in me. Hopefully it will rub off and happen in other places too. I think my game is just well-suited to it.
“I love being at Wimbledon. Today I told my fiance, ‘I don’t want Wimbledon to end’.”
Barty said going out in the fourth round was “nothing to be sad about.”
“For us it’s been an incredible journey to get to this point but it hasn’t changed our approach,” she said.
“Every day I try my best and that’s all I can do. Obviously it’s bittersweet at the moment but nothing but positives from us.”
Serena storms on
The 37-year-old Williams has only played five tournaments this season because of a knee injury, but she insists she is fit and hungry for a first Wimbledon title since 2016.
“I always get excited, I’m a really pumped up player, of course I still want it or else I wouldn’t be here,” she told BBC Sport.
“I’ve had more matches this week than literally the last five months, and now I’m feeling better physically it’s almost relief more than anything.”
Williams is also playing mixed doubles with two-time men’s champion Andy Murray and she says it’s good for her game.
“I think so, I really need the matches and what better a person to play at Wimbledon with than Andy Murray, so I’m really excited.”
