Serena Williams' Wimbledon tournament rolls on, as the women's quarterfinals will be without a top-10 player for the first time in the Open era.
As the No. 25 seed, Williams is in the Wimbledon quarterfinals for the 13th time. She jumped to a 3-0 lead in both sets and wrapped up the win in 62 minutes.
"It was tougher than the scoreline," Williams said. "I knew we were both moms, and I'm not sure how often that's happened, if ever. So it's really cool. You can be a mom, you can still play tennis, and you can still be great."
Rodina, who upset 10th-seeded Madison Keys in the previous round, broke back for 3-2 in the second set but was broken to love straight away.
No. 7 Karolina Pliskova, the last of the top-10 women, lost 6-3, 7-6 (1) to Kiki Bertens. Pliskova had been the only female player in the top 10 to reach the fourth round, the fewest in a Grand Slam event in the Open era following a slew of upsets in the first week. Her loss marks the first time in the Open era that any major has featured a quarterfinal round without a top-10 seed on either the men's or women's side, according to ESPN Stats & Information.
Bertens, who reached the Wimbledon quarterfinals for the first time, hit seven aces and saved eight of the 10 break points she faced. She next faces 13th-seeded Julia Goerges, who beat Donna Vekic of Croatia 6-3, 6-2 to secure her first Grand Slam quarterfinal appearance.
Following Pliskova's exit, No. 11 Angelique Kerber is the highest remaining seed in the women's draw. She advanced Monday with a 6-3, 7-6 (5) victory over Belinda Bencic and will next face Daria Kasatkina of Russia.
Williams is looking for her eighth Wimbledon title and has established herself as the big favorite once again, with the top-10 seeds all eliminated.
Leading 5-4 and two points away from taking the first set at 0-30 on Hsieh's serve, Cibulkova struck a backhand onto the baseline that was called out.
Hsieh returned the ball over the net and into the court as Cibulkova immediately challenged. After the review confirmed the ball landed on the line, umpire Juan Zhang of China awarded the point to Cibulkova.
Hsieh protested, leading the match referee to come on to discuss the decision with the umpire as calls of "replay the point" came from a bemused crowd on Court 18.
After seven minutes, the decision was finally changed and the point replayed. The reprieve was only momentary for Hsieh, as Cibulkova regained her composure to break and take the first set 6-4.
"It never happened to me that the umpire changed the decision," Cibulkova said. "It was really ridiculous for me. It was [a] really bad decision from the supervisor and from the umpire."
Cibulkova advanced to her third Wimbledon quarterfinal, following runs in 2011 and 2016.
The 2017 French Open champion lost her first two service games and was down 5-2 in the opening set before rallying to force a tiebreaker against her Belarussian opponent.
The 12th-seeded Ostapenko was aggressive throughout, hitting 28 winners -- 13 coming off her backhand.
Ostapenko also reached the quarterfinals last year in her best Wimbledon showing, losing to eventual runner-up Venus Williams.
The 21-year-old Latvian, the youngest player remaining in the women's draw, next faces Cibulkova.
"You never know what to expect from her [Ostapenko]," Cibulkova said. "In this tournament, she seems to be in the right mood."
