South Korean tennis star Chung Hyeon has made it to the quarter-finals of the Japan Open.
He beat former U.S. Open Champion Marin Cilic by two sets to one in the last sixteen round on Thursday.
This was the first time in three attempts that Chung has defeated the former world number three.
Chung's quarter-final match against 2017 Tokyo champion David Goffin is taking place as we speak.
