Coco Gauff won her match at the French Open and will play in the next round. She once forgot her rackets for a match. Another player, Frances Tiafoe, joked about it because he had done the same thing before. Tiafoe called her "Mrs. Mature," and she said that you need to be grown-up to play tennis well. Gauff will now play against Madison Keys. People think Gauff is mature because she started playing tennis when she was young and won a big tournament when she was 19.
