But with Serena Williams not playing the 2017 Wimbledon (due to her pregnancy), this is a good chance to take a look at the rest of the playing field. The surface benefits her booming ground strokes, one of the strengths that Coco Vandeweghe of the US couldn't blunt in yesterday's 6-3, 6-3 defeat.
Konta, meanwhile, became the first British player to reach the women's singles semi-finals since Virginia Wade in 1978 by beating Simona Halep.
In the pregnancy absence of younger sister Serena, a revived Williams is back to where she is so accustomed to being, albeit not for almost a decade - eight years removed from her last final - and two decades since her debut at the All England Club.
"It was for sure the best match for a long time for me", Kerber said in defeat.
In a potentially classic semi-final on Thursday, Konta faces American star Venus.
Williams, who is 37 years old, made her Wimbledon debut a few months before Ostapenko was born.
On Centre Court, Williams won all her nine service games, faced only two break points, crackled with 24 winners (to 12 for Konjuh) and made only 13 unforced errors in a performance that was reasonably close to airtight.
Meanwhile Garbine Muguruza, the 14th seeded Spaniard, knocked out battling veteran Svetlana Kuznetsova of Russian Federation 6-4, 6-4 in another quarterfinal clash.
The 2015 Wimbledon finalist Muguruza, seeded No.14, is now set to play against the victor between Slovak Magdalena Rybarikova and American Coco Vandeweghe. Ranked number 304 in the world at the time, she was the lowest-ever-ranked player to beat two Top 10 players in the same event (it has since been bettered by Kim Clijsters in 2009).
"I love the last day you play, you're still improving".
"I definitely feel that age is not a factor with her", Konta said about Williams.
Kim Clijsters won her doubles match with Rennae Stubbs, while former men's champion Richard Krajicek was celebrating again alongside Mark Petchey. Angelique Kerber's loss means she'll relinquish the No. 1 ranking.
The American superstar advanced to her 10th semi-final on London's hallowed grass courts with a record-equalling 86th victory at the All England Club on Tuesday. You're not going to play flawless every round.
"I had a really tough time", Rybarikova said, "and right now, I'm here, and everything paid off".
Williams dominated Wimbledon for nearly a decade between 2000 and 2009, winning five titles and finishing runner-up in another three finals. I think I'm again on a good way to playing again tennis, yeah, on a high level. I am so happy and grateful.
