Following his win, the American tennis star expressed his joy in achieving the feat at such a young age (22 years), stating that while everyone's journey is different, he is following his own path.“I think everyone has a different path. Everyone's story is written differently. I've kind of done it my way,” Ben Shelton said. “There's been a lot of guys to look up to, just because how young they have been when they have broken through and have had so much success at big tournaments. Tennis seems to be a sport that has young champions all the time, which is not common or normal, it's ultra impressive."
