**Osaka Powers into US Open Semi-Finals, Continues Dominant Quarter-Final Streak**

**New York, NY** – Naomi Osaka is back! The two-time US Open champion has stormed into the semi-finals at Flushing Meadows, defeating Czech Republic’s Karolina Muchova 6-4, 7-6 (7-3) in a thrilling quarter-final match. This marks Osaka’s first Grand Slam semi-final appearance since her victory at the 2021 Australian Open and her first since becoming a mother in July 2023.

Osaka, who has never lost a Grand Slam after reaching the quarter-final stage, displayed resilience and determination against the 11th-seeded Muchova. Despite Muchova receiving medical attention for a leg issue during the match, Osaka held her nerve to secure the victory.

“It’s my first time in a semi now [since becoming a mother],” Osaka said after the match. “I was sitting up there watching and hoping I could have the opportunity to play on this court again. This is like my dream is coming true.”

The 27-year-old will now face American Amanda Anisimova, who defeated Iga Swiatek in her quarter-final match. A win against Anisimova would see Osaka make history as the first mother to reach a Grand Slam final since Victoria Azarenka in 2020, which was ultimately won by Osaka. Should she go on to win the US Open, Osaka would become the first player since Kim Clijsters to win a Grand Slam title after giving birth.

Osaka’s recent form has been attributed to her partnership with new coach Tomasz Wiktorowski, known for guiding Iga Swiatek to multiple Grand Slam titles. She reached the final of the Montreal Open last month.

“There’s so much hard work that you guys haven’t seen but I am really grateful to my team and happy to be healthy,” Osaka added.

Tennis fans worldwide eagerly anticipate Osaka’s semi-final clash as she continues her quest for a third US Open title and a place in tennis history.
