American teenager Coco Gauff served superbly to reach her first Grand Slam quarterfinal with a 6-3, 6-1 victory over Ons Jabeur at the French Open on Monday.
Gauff, 17, lost only nine points on her serve.
She also had a quick match in the previous round. Jennifer Brady retired with an injured left foot after Gauff won the opening set.
Gauff will next face Barbora Krejcikova, who also reached her first quarterfinal at a major by beating 2018 French Open runner-up Sloane Stephens 6-2, 6-0.
That win sends Krejcikova into the quarterfinals of a major tournament for the first time.
She saved all three break points faced while Stephens ended up with 26 unforced errors.
Krejcikova won her first WTA title in Strasbourg in the buildup to the French Open. She reached the fourth round at Roland Garros last year.
Stephens won the US Open in 2017 and had her run to the final at the French Open the next year.
