Petra Kvitova slept through Miami’s Ultra Music Festival

MIAMI—The Ultra Music Festival wrapped up its 2023 edition over the weekend, but not before Petra Kvitova made the raucous event into a completely unorthodox white noise machine.

“Last night when I was trying to fall asleep, I heard some good music, and I thought, ‘Ah, this one I know,’ and then I passed out,” she said with a laugh. “I was done! Still, it was probably some good music last night.”

A fierce on-court competitor, Kvitova is beloved by fans for her otherwise placid demeanor, one that often puts her at odds with the wild and crazy cities that light up the WTA tour calendar.

“I think that New York is much crazier than Miami, even with the Ultra Music Festival,” she said after defeating Donna Vekic at the Miami Open for a third time in eight years. “The downtown is pretty crazy right now for those three or four days, but here on site, it feels much easier, much calmer because of the lawn. The space we have here is huge; I feel very free here because it’s very big, even the locker room is a nice size.”

Kvitova has off-set Manhattan’s proverbial hustle and bustle by only commuting to site for match days, and the two-time Wimbledon winner is trying to make similar use of her off-days in spite of South Florida’s searing heat.

“I went to the beach for about an hour on one of my days off, but it’s pretty hot so it’s tough to lie on the sun,” she said. “The sun is nice if you’re taking some energy from it, but too much is too much!”

The former world No. 2 has enjoyed a sunny-enough start to her season, one that kicked into high gear with a “crazy” BNP Paribas Open clash with Jelena Ostapenko. She will next face No. 18 seed Ekaterina Alexandrova for what would be the first Miami Open semifinal of her career.

“I think staying in matches, mentally has been the key,” she said, though she entertained a theory that both Indian Wells and Miami’s access to turf—albeit for exercise—has put her in a Wimbledon mood.
