After an upset of ginormous proportions against World No. 3 Coco Gauff, four-time Grand Slam champion Naomi Osaka returns to her favorite den. The Japanese superstar locks horns with two-time semifinalist Karolina Muchova in the 2025 US Open quarterfinals on Wednesday. The two players have fought tooth and nail in some classics over the years, and the clash in New York is going to be nothing short of the same. With the help of BetMGM, we will preview this last eight battle on Arthur Ashe Stadium.

Karolina Muchova vs Naomi Osaka Match Preview

World No. 13 Karolina Muchova is the official marathon woman of the 2025 US Open. Unlike Naomi Osaka, the Czech sensation has been mightily challenged in every encounter thus far. It has been a stop-start season for the 29-year-old, with consecutive semifinals in Linz and Dubai being her headliner achievements this year. The Roland Garros runner-up from 2023, Muchova has a win-loss record of 20-12 so far. She has beaten Venus Williams, Sorana Cirstea, Linda Noskova and Marta Kostyuk en route to the last eight.

According to her own admission, saving match points against Samsonova in the Montreal Round of 64 flipped the switch for Naomi Osaka. The two-time US Open champion went on to reach the final on Canadian soil, before regaining Grand Slam form at Flushing Meadows. Apart from this, Osaka also won the WTA-125 in Saint-Malo and reached the final in Auckland to start her season. The World No. 24 has won over 76% points on first serve throughout the competition. She has beaten Greet Minnen, Hailey Baptiste, Daria Kasatkina and Coco Gauff to reach the quarterfinals.

Just two months after giving birth to her daughter Shai, Naomi Osaka was in the stands to watch Coco Gauff at the 2023 US Open.

Karolina Muchova vs Naomi Osaka US Open 2025 Prediction

Having played four consecutive three setters, fatigue is naturally set to kick in for Muchova. The 29-year-old was also battling back issues against Kostyuk, which could play a role. However, she is one of the few players who can match Osaka from the baseline. The former US Open champ is striking the ball more fiercely than ever. More than anything, it was her tactically astute game-style and positive mindset that carried her over the line against Gauff. Having won their most recent contest, we expect Osaka to repeat the heroics.

Prediction: Naomi Osaka in three sets.

Naomi Osaka and Karolina Muchova will face each other in the US Open QF.

Their head to head is 2-2.

Naomi won their most recent meeting earlier this year at the Australian Open.

But Karolina won when they played at this event last year.
