“I think she’s far away from everybody,” said the third-seeded Karolina Pliskova, who will play Hsieh in the third round on Friday. “The style is just, I don’t know — nobody has it .”

Pliskova has had two tough matches with Hsieh, winning in a third-set tiebreaker in Miami last year, and losing, 7-5, in the third in Dubai this year.

Hsieh’s quirks extend beyond the court, and her interviews can be just as unpredictable as her game.

“Sometimes I do hit very hard, but I like to mix a little bit,” Hsieh said Wednesday. “Depends on my mood, depends on my hair today. Or maybe there’s a handsome guy cheering for me.”

She quickly added in an exaggerated stage whisper: “Shh, don’t write this. My boyfriend might see.”
