Wimbledon CNN  — 

Even a late change of location Wednesday couldn’t halt the momentum of Cori Gauff, the teenager making history virtually every time she steps onto Wimbledon’s fabled grass.

Already the youngest ever to emerge from qualifying and youngest since 1991 to win a match in the main draw when she beat idol Venus Williams, the 15-year-old American became the first player to win a full match under the oldest grand slam’s new Court One roof.

It was another straight-set victory, too, 6-3 6-3 over Magdalena Rybarikova.

The 30-year-old Slovak’s ranking might have slipped to 139th in the world, but in 2017, she found herself in the last four at Wimbledon.

“I don’t even know how I played, if I played better or not,” Gauff said. “I like to say maybe I played a little better.”

“Amazing” was how the USTA’s general manager of player development, Martin Blackman, summed up her performance.

“After she had a huge win like she had in the first round, to come back with that much poise against a woman who got to the semis here two years ago and who is very good on grass, it’s just remarkable,” Blackman said.

Will Gauff emulate Jennifer Capriati’s semifinal achievement of 28 years ago?

We’ll know more over the coming days but one thing is already certain: Wimbledon fans are head over heels for the player nicknamed “Coco.”

That doesn’t surprise Blackman.

“She’s such a gracious young lady, great sportsmanship,” he said. “We saw a couple of times when Rybarikova hit great shots that Coco kind of clapped with her racket, really classy. But I think they just love seeing a young woman like that who is so gifted, such a great competitor.”

Cries of “Come on, Cori” broke the silence between points, and a hush descended when Gauff slipped and did the splits late in the second set.

A thumbs up, to their relief, confirmed that she was OK.

New fan favorite

And when Rybarikova double-faulted to bring up a first match point at 5-3 in the second, the decibel level rose with cheers – and applauding on double faults usually contravenes tennis etiquette.

Gauff smiled and waved to her new adoring public as she left the court about 9.15 p.m. local time, probably not far off her usual bedtime.

“That smile at the end said everything,” Blackman said.

It was an ‘A’ performance from Gauff, who took a science test during her qualifying run while reaching the main draw.

She was due to face Rybarikova on Court Two – still a big stage, especially for two unseeded players – but organizers shifted the contest to the second show court when matches on Court 2 ran late.

Perhaps memories of defeating Williams in the same arena two days ago boosted Gauff.

She looked at home in only her second ever Grand Slam outing.

Many a player before her has struggled to follow up massive victories, but Gauff seems a character hard to ruffle.

It’s difficult to believe, then, that she found it difficult to focus against Rybarikova.

“I could lie and say I felt normal,” Gauff said. “It was honestly so hard just with social media and everything trying to focus on [Wednesday’s match] because people are still posting about Venus.

“I wasn’t expecting any of this. A lot of celebrities were [direct messaging], posting me. I’m kind of starstruck.”

As news filtered across the grounds that an extra match would be played on Court One, a 40% full stadium became around 80% by the time the first set ended.

People are taking note.
