Baby No. 2 is on the way for Petra Kvitova

Just about two months ago, Petra Kvitova was saying goodbye to tennis after losing in the first round of the US Open.

In a few months from now, she'll be saying hello to a new family member.

The recently-retired former world No. 2 announced Thursday that she and husband Jiri Vanek are expecting their second child.

The two-time Wimbledon champion married Vanek, her longtime coach, in 2023, and gave birth to son Petr fittingly during the Wimbledon fortnight last year. After a 2025 comeback for the love of the game rather than for results, the now-35-year-old announced in June that the US Open would be the final tournament of her career, got an emotional send-off at the grass-court Grand Slam that she won twice, and officially bid farewell to the tour after losing to France's Diane Parry in New York.

Little Petr, now 16 months old, played a part is sharing the news about Kvitova's next chapter. She posted a photo of her family of three to Instagram on Thursday, and wrote in the caption in Czech and English: "Our little boy will soon become a big brother."

A popular player amongst her peers during her career, Kvitova received congratulatory messages from players including Belinda Bencic, Sorana Cirstea, Carla Suárez Navarro and Elena Vesnina.

She had confessed ahead of her final tournament that she was "ready to stop," and hoped to have another child in the not-too-distant future after hanging up her racquets. She won just one of the nine matches she played after coming back to the tour.

"“Mentally, I think I can’t do it any more, as well as emotionally and physically. ... You still remember how you played before, how everything was smooth and I was hitting winners and suddenly it’s not there," she said.

“I’m totally ready. I’m not regretting anything. I still love tennis but everything else, waiting for the practices, waiting for the car, waiting for a match, it’s just tiring. And having a son, it’s a totally different life. I just want to spend more time with him as well."
