NEW YORK (AP) — Coco Gauff and Naomi Osaka have started their much-anticipated matchup in the U.S. Open's fourth round on Monday.

Gauff , a 21-year-old from Florida, is the Grand Slam tournament's No. 3 seed. Osaka , a 27-year-old who was born in Japan and moved to the U.S. with her family at age 3, is the No. 23 seed.

They have won a combined three titles at Flushing Meadows.

Monday's winner will make it to this year's quarterfinals and face No. 11 Karolina Muchova or No. 27 Marta Kostyuk.
