Qualifying for the main draw with a win over Julia Boserup, her tournament began with a win over Mutua Madrid Open semifinalist Louisa Chirico, and took a dramatic turn in a second-round thriller against No.16 seed Kiki Bertens.
Playing well into the night thanks to rain delays, Ozaki outlasted Bertens in three tough sets to reach the third round. Keeping up that momentum, she pulled off one last upset against Julia Goerges, this time in straight sets.
Those wins earned her the right to battle World No.1 Angelique Kerber in the round of 16, where she ultimately fell in two.
Still, it was a banner week for the the 23-year-old, and looking to build on her new career-high ranking of No.72, Ozaki is your Breakthrough Player of the Month!
