The Latest: Venus Williams into fourth round of US Open
Venus Williams, of the United States, returns a shot from Maria Sakkari, of Greece, during the third round of the U.S. Open tennis tournament, Friday, Sept. 1, 2017, in New York.
The Latest on the U.S. Open, the year's last Grand Slam tennis tournament (all times local):
Venus Williams is into the fourth round of another major after beating Maria Sakkari of Greece 6-3, 6-4.
The No. 9 seed reached the second week for the seventh straight major, the longest active streak in women's tennis. It's the first time since 2010 that she reached the fourth round in every major.
However, Williams was eliminated earlier Friday from a chance at the No. 1 ranking when Garbine Muguruza reached the round of 16.
Third-seeded Garbine Muguruza needed a little over an hour to move into the U.S. Open fourth round.
Muguruza, this year's Wimbledon champion, defeated 31st-seeded Magdalena Rybarikova of Slovakia 6-1, 6-1. The Spaniard has yet to lose a set at Flushing Meadows this year and has dropped only nine games.
Next up for Muguruza is two-time Wimbledon champion Petra Kvitova, the No. 13 seed, who beat 18th-seeded Caroline Garcia 6-0, 6-4.
Canadian teenager Denis Shapovalov is the youngest man to reach the U.S. Open's fourth round since Michael Chang was 17 in 1989.
The 18-year-old Shapovalov advanced to the round of 16 at a major tournament for the first time when Kyle Edmund of Britain stopped playing because of a neck injury.
Sloane Stephens of the United States, returns a shot from Ashleigh Barty, of Australia, during the third round of the U.S. Open tennis tournament, Friday, Sept. 1, 2017 in New York.
Sloane Stephens is into the U.S. Open's fourth round, something she last did in 2013.
The 24-year-old American won for the 11th time in her past 13 matches as she continues her comeback from foot surgery, beating Ashleigh Barty of Australia 6-2, 6-4.
Stephens went 11 months without entering a tournament because of an injured left foot. She returned to the tour at Wimbledon in July.
Before reaching consecutive semifinals at hard-court tournaments in Toronto and Cincinnati in August, Stephens was ranked 934th.
She came to Flushing Meadows at No. 83rd and will keep rising.
Not too long ago, Stephens appeared to be a rising star in tennis, making at least the fourth round at six consecutive Grand Slam tournaments, including a semifinal run at the 2013 Australian Open.
Now she is into the second week at a major for the first time since the 2015 French Open.
Past U.S. Open champion Marin Cilic made 80 unforced errors and was beaten in the third round by 29th-seeded Diego Schwartzman of Argentina 4-6, 7-5, 7-5, 6-4.
Cilic won the 2014 title at Flushing Meadows. His loss means there will be a first-time Grand Slam finalist this year from the bottom half of the draw. Only one man left on that side of the bracket has even made it as far as the semifinals at a Grand Slam tournament.
Marin Cilic of Croatia returns a shot from Diego Schwartzman of Argentina, during the third round of the U.S. Open tennis tournament, Friday, Sept. 1, 2017 in New York.
Schwartzman is into the fourth round at a major for the first time.
The only past Grand Slam champion in the lower half of the U.S. Open's men's draw is in trouble.
Marin Cilic, who won the title at Flushing Meadows in 2014, is trailing 29th-seeded Diego Schwartzman of Argentina 4-6, 7-5, 7-5 in the third round.
They are on the side of the bracket that originally had three-time major champion Andy Murray, but he withdrew two days before the tournament started because of a hip injury.
Pablo Carreno Busta reached the fourth round at the U.S. Open for the first time by easily eliminating qualifier Nicolas Mahut 6-3, 6-4, 6-3.
Carreno Busta compiled an impressive disparity of 32 winners to only 13 unforced errors Friday.
The 12th-seeded Spaniard has only once been as far as the quarterfinals at a Grand Slam tournament, at the French Open in June.
Mahut, ranked 115th, is best known for losing the longest match in tennis history, 70-68 in the fifth set against John Isner at Wimbledon in 2010.
Two-time Wimbledon champion Petra Kvitova moved into the U.S. Open's fourth round with a 6-0, 6-4 victory over 18th-seeded Caroline Garcia of France.
It was only the 19th match of the year for Kvitova, who missed the first half of the season after she was cut on her left hand — the one she holds her racket with — during an attack by a knife-wielding intruder at her home in the Czech Republic in December. Garcia, in contrast, has played 52 matches in 2017.
The 13th-seeded Kvitova is in the fourth round at Flushing Meadows for the third time in a row. She lost at that stage to eventual champion Angelique Kerber a year ago.
Kvitova never faced a break point Friday and raced through the first set in 26 minutes. Garcia finally grabbed a game to begin the second set, which was more competitive until Kvitova broke for a 4-3 edge.
Five women still remain in contention for the No. 1 ranking as the U.S. Open's third round begins.
Venus Williams and Garbine Muguruza are among them and try to reach the fourth round by winning Friday.
Two of the others, current No. 1 Karolina Pliskova and Elina Svitolina, will play Saturday.
The fifth, Simona Halep, lost in the first round to Maria Sharapova.
Action is underway on Day 5, with two-time Wimbledon champion Petra Kvitova facing 18th-seeded Caroline Garcia in Arthur Ashe Stadium. Later, Williams meets Maria Sakkari, and Muguruza plays No. 31 Magdalena Rybarikova.
Sharapova plays at night against American wild-card entry Sofia Kenin.
