Chung enjoyed a career-best quarterfinal run in Miami this week, eventually falling to John Isner 6-1, 6-4. In a disappointing end to to his tournament, Chung won just one single point off the American's first serve.

Still, the 21-year-old is currently fourth in the 2018 Race to London, with no other 21-and-under players in the year-to-date Top 10, so he'll definitely be one to keep an eye on as the season progresses.
