Anna Kalinskaya, provocative (and provocative) selfie in the bathtub at'1 a.m.

Not only Jannik Sinner starred in Cincinnati nights. Anna Kalinskaya also did well in Ohio, climbing all the way to the quarterfinals of the women’s draw.

The Russian, in the very quarterfinals, however, was called to a mission impossible against the number 3 seeded Iga Swiatek, winner 6-3, 6-4 and qualified for the semifinals.

Kalinskaya, after the quarterfinals ended at a late hour, had been forced to re-energize well past 1 a.m., as evidenced by a story posted on Instagram showing her in a bikini in a pool, probably iced over for faster recovery from her exertion.

Kalinskaya also provoked her followers with the caption “What are you guys doing? ” followed by a laughing smiley face that certainly led to a flood of direct chat messages.
