Another top women’s seed is done at the U.S. Open.

After the No. 1 player in the world Iga Swiatek — the defending champion — was bounced on Sunday night and top-seeded American Jessica Pegula, seeded third, was sent home on Monday morning, No. 7 seed Ons Jabeur was upset in the Round of 16.

The Tunisian star fell in straight sets to No. 23 seed Qinwen Zheng at Louis Armstrong Stadium, 2-6, 4-6.
