Only four men and four women are left in the U.S. Open singles draw, and the crowds at Arthur Ashe Stadium continue to draw A-Listers. Case in point: Last night, actress Christine Baranski was among those watching Naomi Osaka defeat Karolína Muchová and Jannik Sinner triumph over fellow countryman Lorenzo Musetti.

After Osaka won her quarterfinal match, the camera panned to Baranski applauding. As one fan posted on X, “Naomi Osaka just reached the pinnacle of human achievement (she did something cool and the camera cut to Christine Baranski clapping for her).”
For the evening, Baranski wore a Thom Browne nautical toile blazer over a black silk button down. She accessorized with large hoop earrings, a pearl necklace, and a pendant necklace.

Last night appeared to be just Baranski’s second time attending the U.S. Open; she was also pictured at the tournament in 2014, attending the men’s finals where Marin Čilić defeated Kei Nishikori.
