Chung shows off smooth skills in frame challenge

Here's a challenge you can try at home. Hyeon Chung won Tennis TV's "Frame Game" by bouncing a ball off the edge of his racquet an impressive 50 times without dropping it.

In doing so he blew away the competition, with Karen Khachanov getting 32:

And Jeremy Chardy racking up 28:

While Chung's win seems impressive, Rafael Nadal's 2014 Wimbledon attempt puts them all to shame with a whopping 406:

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.
