Karolina Pliskova has accomplished what 10 others have tried and failed to do over the past month: beat Naomi Osaka.

The hard-serving Czech spoiled the party in front of a decidedly pro-Osaka crowd in Tokyo on Sunday, taking the Toray Pan Pacific Open title with a 6-4, 6-4 win over her Japanese opponent.

Pliskova's win ends an incredible September run by Osaka that saw her take the U.S. Open and roar through the Pan Pacific draw without dropping a set as the buzz over her grand slam win reverberated across the country.
