Wimbledon 2025: Could Osaka Upset Odds Against Siniaková After Zheng’s Big Wimbledon Shock?

July 02, 2025: Naomi Osaka’s path at Wimbledon 2025 may have seemed to open up after No. 5 seed Zheng Qinwen crashed out in the first round—but in reality, the former world No. 1 now faces a potentially tougher challenge in Katerina Siniakova, the very player who sent Zheng packing.

🎾 Osaka vs. Siniakova: A Clash of Styles

Katerina Siniakova, ranked No. 1 in doubles and once as high as No. 27 in singles, has proven to be a dangerous floater in the draw. Her flat-hitting, grass-friendly game gives her an edge on the surface—and she now holds a 3-1 record against Zheng, including two Wimbledon wins.

“She robs you of time,” said Prakash Amritraj. “She goes hard up the middle and makes you hit uncomfortable balls. She forced a bunch of errors off Zheng’s forehand. Osaka may struggle with that kind of pace.”

Lindsay Davenport, 1999 Wimbledon champ, noted: “Siniakova is a very good grass-court player… But this is a good section of the draw for Osaka if she can make her way through. I’m torn.”
