Coco Gauff just won her first match at the US Open and now will play Timea Babos in her second round match. She’s only 15 and won 3 matches at Wimbledon, but can she go even further at the US Open?
Coco won her three matches at Wimbledon against opponents not ranked in the top 30. When she lost it was in straight sets to Simona Halep, the No. 7 in the world at the time. I can’t deny that it is very impressive what she did, but when it comes to the top players, she struggles.
So, by my theory the run will end earlier because if she makes the third round, she will most likely play Naomi Osaka, the No. 1 in the world. Coco tends to struggle with her serve and forehand and playing Osaka, she will capitalize on those mistakes.

Once her experience and IQ increases, she will handle those matches better and start to make more runs, more money, and more trophies.
