PARIS -- A day after Serena Williams was eliminated from the French Open, 17-year-old Coco Gauff showed the future in tennis for American women is bright.
Gauff served superbly to reach her first Grand Slam quarterfinal with a 6-3, 6-1 victory over Ons Jabeur on Monday.
Gauff lost only nine points on her serve and was also highly effective at the net, winning 13 of 17 points when she came forward -- which was especially impressive against a player who is known for her shot-making skills.
"I feel like this has been the most consistent tennis I have played at this level," Gauff said. "Hopefully I can keep that going."
Gauff also had a quick match in the previous round, when Jennifer Brady retired with an injured left foot after Gauff won the opening set.
Jabeur said Gauff is a contender to raise the trophy -- either this year or in the future.
"If she's not going to win it now, she's probably going to win another time," the Tunisian said.
It wouldn't be the first time Gauff claims a title at Roland Garros, having won the girls' singles title in 2018.
"She's young, she's amazing, she's coming up. She's going to be the next star," Krejcikova said of Gauff.
Seeded fourth, Kenin was the runner-up at Roland Garros last October and was seeking her second major title.
Sakkari, seeded 17th, advanced to her first career Grand Slam quarterfinal and earned her sixth win against a top-20 player this year.
Another quarterfinal will be Sakkari against defending champion Iga Swiatek, at No. 8 the highest-seeded player left in the women's draw. She eliminated Marta Kostyuk 6-3, 6-4 and has won 22 consecutive sets at Roland Garros.
Gauff, Krejcikova and Sakkari are three of the six women making Grand Slam quarterfinal debuts, the most at any major in the professional era.
Kenin lost serve six times and had 32 unforced errors to 15 for the steady Sakkari.
Gauff already announced herself as a contender to become the next great American player when she made a run to the fourth round at Wimbledon as a 15-year-old qualifier two years ago. Now, having gone one step further, she became the youngest American to reach a Grand Slam quarterfinal since Venus Williams did it at 17 at the 1997 US Open.
"I'm only going to be 17 once, so you might as well talk about it while I'm 17," Gauff said.
Gauff has not dropped a set in Paris this year. She won both the singles and doubles titles at a warmup tournament in Parma before coming to Paris. That came after a run to the semifinals of the Italian Open.
In all, she's on a career-best nine-match winning streak.
"Parma gave me a lot of confidence, especially on the clay," Gauff said. "It taught me a lot about how to close out matches and deal with the pressure on important points."
It's been a breakthrough year in singles for Krejcikova, 25, who won her first WTA title in Strasbourg in the buildup to the French Open. Her victory over Stephens on Court Suzanne Lenglen extended her current winning run to nine matches.
Until now, Krejcikova was mainly known for her doubles accomplishments. She is a former No. 1 in the specialty and has won two Grand Slam titles with teammate Katerina Siniakova. They play in the doubles quarterfinals Tuesday.
Stephens committed 26 unforced errors against Krejcikova.
