Teenage sensation Coco Gauff battled through the opening round at the US Open on her main-draw debut in New York.
Gauff, 15, overcame fellow teenager Anastasia Potapova 3-6 6-2 6-4 at Louis Armstrong Stadium on Tuesday.
The American rose to stardom at Wimbledon earlier this year, making the fourth round at the All England Club.
Gauff's main-draw debut at her home major went to plan, but only after a nervy start against the 18-year-old Russian.
The teenagers each committed 16 unforced errors in the opening set before Gauff steadied, eventually moving through in two hours, one minute.
