NEW YORK (AP) — Here’s how new all of this is to Coco Gauff: She didn’t quite realize she only has to play every other day at the U.S. Open.

“I’m still used to playing juniors,” the American said with a chuckle, “so I forgot about the day off.”

She’s still just 15. She’s competing in just her second Grand Slam tournament. And yet she’s definitely showing she can perform like someone much older and more experienced.

With her parents jumping out of their front-row seats over and over again, and a raucous partisan crowd backing her at Louis Armstrong Stadium, Gauff trailed by a set and a break, then again by a break in the third set, before coming up big down the stretch to get past Anastasia Potapova of Russia 3-6, 6-2, 6-4 in her debut at Flushing Meadows.
