Coco Gauff won her match at the French Open and will play in the next round. Before the match, she forgot her rackets. Another American player, Frances Tiafoe, joked with her because he had done the same thing. He called her "Mrs. Mature," and she said that playing professional tennis makes you grow up fast. Coco will play against Madison Keys next. She also said that people think she is mature because she started playing well in tennis when she was young, like at Wimbledon when she was 15 and when she won her first big title at 19.
