The Czech has been excellent at the US Open so far. She started her campaign by cruising past Sorana Cirstea and Linda Noskova in the initial few rounds and then brushed aside Marta Kostyuk in the fourth. She outlasted Kostyuk in a thrilling three-set bout, 6-3, 6-7(0), 6-3.

Naomi Osaka vs Karolina Muchova prediction
Osaka deserves a place in the last eight for her constant efforts this year. She also dropped down a level to play in Saint Malo and work on her rhythm. She's a two-time champion in New York and will now know how to absorb the pressure in the next round.
Muchova, on the contrary, hasn't achieved a significant result at any of the events so far. She's showcased her resilience and match fitness with close wins in the last few rounds. She hopes to recover well before the quarterfinals and present a stern challenge for Osaka.
Muchova's accuracy will go toe-to-toe against Osaka's power in the last eight. Both players are skilled at volleying the tennis ball. Considering their freshness in New York and performances in the previous few rounds, Osaka will be a slight favorite to come out on top.
Pick: Osaka to win in three sets.
