Igaświątek came from the set and extended the French Open victory on an injury to Elena Rivakina, winning 1-6, 6-3, 7-5 on Sunday.
Three-time defending champion świątek has now recorded 25 consecutive main draw wins for Roland Garos, with Chris Ebert being the only woman in the open era, turning 29.
She was forced to work hard against former world No. 3 Rybakina.
Rivakina, who scored a 5-0 lead before closing the opening set in just 35 minutes, scored the first eight points of the second set, taking full control of the four-round contest.
However, świątek met in the second part of the match, winning the sixth Grand Slam title and locking out Rivakina to continue his fifth hunt at the French Open.

“I was feeling pretty bad (at the start of the match) so I was accepting that I could lose it,” świątek later told reporters. “But that didn’t change the fact that I wanted to fight for it anyway.”
World No. 5 will play 13th seed Elina Svitolina in the quarterfinals after the Ukrainian defeated last year’s runner-up Jasmine Paolini on Sunday.
świątek, who won the straight set in the opening of the three rounds of the tournament, faced her first real test against Rivakina at this year’s French Open. She saved 10 breakpoints during the match and edged only frontally at the final stage of the decision set.
It was not a skilled victory for the Polish planet, it was brave. She made seven uncharacteristic double faults during the match. This includes three games in one game in the second set.
However, in the context of her title defense, this kind of victory may feel more important than the many everyday victory she had in Paris.
“I think that kind of victory is necessary… you can win under pressure. Even if it’s not going in the right direction, you can still win to spin the match and win,” świątek said.
“It’s certainly a great confirmation for me. Obviously, it’s great to have full control over the game, but it’s not always possible for great players.
Another defending champion, Carlos Alcaraz, overcomes his challenging opponent to reach the quarterfinals, beating America’s 13th Seed Ben Shelton 7-6 (8), 6-3, 4-6, 6-4.

Alcaraz had to save three set points to avoid passing the early lead to Shelton. And he faced six breakpoints in the first game of the second set.
Shelton had a faint glow of hope when he won the third set, but the Spaniards fought back in the fourth, showing once again his advantage over Clay to secure his 100th victory on the surface.
Entering the tournament behind his victory in Monte Carlo and Rome, Alcaraz is about to win his fifth Grand Slam title and capture the second in the French Open. On Tuesday, he faces America’s Tommy Paul and wins a spot in the Final Four.
