Us open ex tennis champion stephens ousted by russian qualifier

You're referring to the 2022 US Open!

Yes, you're correct. Sloane Stephens, the 2017 US Open champion, was upset by Russian qualifier Anna Kalinskaya in the second round of the 2022 US Open. Kalinskaya won the match 6-4, 6-4, sending a shockwave through the tennis world.

Stephens, who was seeded 26th in the tournament, was expected to have an easier time against the unseeded Kalinskaya. However, the Russian qualifier played a solid match, using her powerful forehand to great effect and taking advantage of Stephens' struggles with her serve.

Kalinskaya's victory marked her first Grand Slam win and sent her into the third round of the US Open, where she ultimately lost to top-seeded Iga Świątek.
