Zheng, 19, entered the U.S. Open ranking 39th in the world. She started this season from world No.143, and had an impressive run at Roland Garros (in May) stunning Grand Slam with winner Simona Halep of Romania and French veteran Alize Cornet to reach the last 16 in what was her second Grand Slam campaign.

Zheng will meet Anastasia Potapova from Russia in the second round.

Yuan, 23, will meet either Elise Mertens of Belgium or Romania's Irina-Camelia Begu in the next round after her first victory in a Grand Slam main draw.

In the men's singles, Rafael Nadal shook off doubts on him after his loss in Cincinnati and moved past Australian Rinky Hijikata 4-6, 6-2, 6-3, 6-3 to set up the next round with Italian Fabio Fognini. Fellow Spaniard Carlos Alcaraz also advanced as Sebastian Baez of Argentina retired due to a leg injury in their first round matchup.
