Naomi Osaka's bid for a second straight US Open title came to an end Monday.
Ranked No. 1 in the world, Osaka lost 7-5, 6-3 to the 13th-seeded Belinda Bencic.
This marks the second time Bencic has reached the quarterfinals at Flushing Meadows, having previously done so in 2014.
With Osaka out, that leaves No. 5 seed Elina Svitolina as the highest seed remaining in the women's draw.
