Serena Williams will continue her quest for a record-equalling 22nd Grand Slam title when she faces Anastasia Pavlyuchenkova in the Wimbledon quarter-finals on Tuesday.
The world No 1 and defending champion won the last nine games in a row to beat Svetlana Kuznetsova in the fourth round.
Pavlyuchenkova, who turned 25 on Sunday, reached her first Wimbledon quarter-final with a straight-sets win over Coco Vandeweghe.
Dominika Cibulkova could be forced to postpone her wedding if she beats Elena Vesnina in their quarter-final.
The 19th seed is scheduled to get married on Saturday, the date of the women's final.
But, speaking after her impressive three-set win over third seed Agnieszka Radwanska, said: "If I win on Tuesday, then we will change it. We will postpone it because it will be a big rush.
"It was just when I was in an ice bath after the match, I said to my team, 'Okay, now it's getting more serious'. It's no problem. We chose this date because I never saw myself as such a great grass-court player."
Australian Open champion Angelique Kerber is yet to drop a set and faces fifth seed Simona Halep in the last eight.
"I'm feeling my tennis is getting better and better every day. This is what counts in the second week of a Grand Slam," said the German.
Kerber beat Misaki Doi in straight sets in the fourth round while Halep came through 6-7 (5-7) 6-4 6-3 against Madison Keys.
Venus Williams, the oldest Wimbledon women's quarter-finalist for 22 years, faces Yaroslava Shvedova, a 6-2 6-4 winner over Czech 28th seed Lucie Safarova.
"Am I surprising myself? The first time you win nobody picks you and the last time you win nobody picks you. You always have to believe in yourself," said 36-year-old Williams.
