Pliskova and Gibbs have faced off twice before — in Seoul, South Korea, in 2014 and in Sydney, Australia, in 2015. This is the first time Pliskova triumphed.
Pliskova will need to reach the final to have a chance at retaining her No. 1 ranking.
■ Another seeded player will not be continuing here. Jennifer Brady upset No. 23-seeded Barbora Strycova in dominant fashion on the Grandstand.
“I came out with lots of energy and I played her before, so I knew what to expect,” Brady said of the 6-1, 6-1 victory in an on-court interview. “I think I learned her game style and the way she competes. I knew it was going to be a tough match, so I brought my A game and I’m happy I played well.”
Brady, who entered the Open ranked No. 91, lost to Strycova in Stuttgart, Germany, in April. Strycova had 25 unforced errors and only six winners in the match.
■ Fourth-seeded Elina Svitolina continued her quest to leave the Open with the WTA’s No. 1 ranking, beating Evgeniya Rodina of Russia, 6-4, 6-4, at Arthur Ashe Stadium.
Svitolina is one of six women in contention to finish the Open ranked No. 1.
After the match, she said that even though earning that spot would be nice, it was not at the forefront of her mind while she is playing.
“I don’t think about those things,” Svitolina said on the broadcast after her match. “Of course, for each player, to reach No. 1 in the world is a massive deal and it’s great, but I really want to go far in this tournament and take it one match at a time.”
■ Struggling with what appeared to be a back injury, 15th-seeded Tomas Berdych lost to Alexandr Dolgopolov, 3-6, 6-1, 7-6 (5), 6-2.
Matches to Watch on Thursday
How to watch: You can stream matches here (streaming began at 11 a.m., Eastern time). TV coverage begins on ESPN2 at 1 p.m.
No. 15 Madison Keys vs. Tatjana Maria
Not before 5:30 p.m., Louis Armstrong Stadium
Keys has reached the fourth round here in each of the last two years and faces the 61st-ranked Maria of Germany as she aims to make it back to the second week. The two met at Wimbledon in 2015, and Keys won in straight sets. Look for her to replicate that result, as her power game matches up well with Maria’s one-handed backhand.
No. 8 Svetlana Kuznetsova vs. Kurumi Nara
Fourth match, Grandstand
Kuznetsova won the United States Open in 2004 and was a finalist three years later. But she has not advanced past the third round here since 2013. Nara was only 13 when Kuznetsova picked up her Open trophy. The two have met once before, when Nara was a teenager, and Kuznetsova won handily. Kuznetsova rallied to win a grueling first-round match against Marketa Vondrousova on Wednesday and needed treatment on her left wrist.
No. 3 Roger Federer vs. Mikhail Youzhny
Third match, Ashe Stadium
After being pushed to five sets against Frances Tiafoe in his first-round match, Federer looks to get back on track against a familiar opponent. In 16 matches over 15 years, Youzhny has never beaten Federer. Unless the 17th time is the charm, this match will serve mostly as a barometer of Federer’s form: Was his stiffness on Tuesday night a result of his back, his form or just Tiafoe’s quality?
No. 6 Dominic Thiem vs. Taylor Fritz
Third match, Louis Armstrong Stadium
Fritz, 19, won his first United States Open main-draw match on Wednesday, and his reward was a matchup against Thiem. The two have never met, and although they are separated by 100 spots in the rankings, stylistically the matchup could make for great tennis. If Fritz can get his teeth into the match and get the crowd behind him, it will be worth a look as the day wraps up. Fritz also has a good-luck charm at the Open: his seven-month-old son, Jordan.

■ Fourth-seeded Alexander Zverev, the highest seed on the bottom half of the men’s singles draw, crashed out of the tournament with a four-set loss in the second round to a fellow 20-year-old, Borna Coric.
■ No. 14-seeded Nick Kyrgios, another young star, flamed out in the first round, struggling with a shoulder injury in a loss to John Millman, ranked 235th.
■ As some rising young stars fell, another grew brighter: 18-year-old Denis Shapovalov ousted eighth-seeded Jo-Wilfried Tsonga in the second round.
■ Maria Sharapova’s Grand Slam comeback continued with a win over Timea Babos, and now she has a wide-open draw, too. No. 16 Anastasija Sevastova is the highest remaining seed in Sharapova’s quarter of the draw.
