Naomi Osaka has never failed to win a Grand Slam after reaching the quarter-finals

Two-time US Open champion Naomi Osaka says her "dream is coming true" as she made her return to the semi-finals in New York with victory over Karolina Muchova.

Playing her first Grand Slam quarter-final since she won the 2021 Australian Open, Japan's Osaka held her nerve to beat the Czech 11th seed 6-4 7-6 (7-3) on Arthur Ashe Stadium.

Getting back to the last four of a major is another impressive milestone for Osaka, who did not play for 14 months around the the birth of daughter Shai in July 2023.

"It's my first time in a semi now [since becoming a mother]," Osaka said.
