Coco Gauff, a 15-year-old American tennis prodigy, and Naomi Osaka, the world’s No. 1 player, will face each other in a tournament for the first time when they meet in the third round of the United States Open on Saturday.
The high-profile match is likely to be played in Arthur Ashe Stadium, the largest permanent tennis stadium in the world with its five tiers of seating and capacity for nearly 24,000 spectators.
But Osaka and Gauff have been crossing paths in much smaller and quieter venues for some time.
