NEW YORK — Naomi Osaka returned to the U.S. Open quarterfinals by taking advantage of some early jitters for Anett Kontaveit and showing no ill effects from a recent left hamstring problem.
The fourth-seeded Osaka never faced a break point and beat the 14th-seeded Kontaveit 6-3, 6-4 in Arthur Ashe Stadium.
Osaka owns two Grand Slam titles, including Flushing Meadows in 2018. She lost in the fourth round a year ago.
Kontaveit won the match’s first point, but followed that with a pair of double-faults, followed by a pair of backhand errors to get broken.
And Osaka was on her way, winning 35 of 45 service points.
The 22-year-old from Japan improved to 5-0 head-to-head against Kontaveit and now faces unseeded Shelby Rogers of the United States in the quarterfinals.
Rogers has won all three matches she’s played against Osaka.

The Greek player will next face Maryna Zanevska of Belgium after she eased past Dalma Galfi 6-1, 6-3.
Fourth-seeded Sloane Stephens of the United States, the 2017 U.S. Open champion, lost to Danka Kovinic 7-5, 2-6, 7-5.
Kovinic will face Jasmine Paolini in the quarterfinals after the Italian defeated compatriot Elisabetta Cocciaretto 4-6, 6-3, 6-4.
