Having brushed aside some of the biggest names in the sport already,... Korea's up-and-coming tennis star Chung Hyeon faces the biggest moment of his life today: an Australian Open semi-final against the man widely considered to be the greatest player in history, Roger Federer.
Park Se-young has more.
His white-rimmed glasses catch the crowd's attention.
Korea's up-and-coming tennis star Chung Hyeon will face World number two Roger Federer in the Australian Open semi-finals on Friday.
Federer has a staggering 19 Grand Slam titles under his belt, ...including five Australian Open titles;
Chung is ranked 58th in the world.
The match comes as Korea is in the grips of the "Chung Hyeon fever" with the nation seeing a huge jump in sales of tennis goods.
The semi-final begins at 5:30 p.m. Friday, Korea time, with the winner facing Croatian Marin Cilic (chee-leech) in Sunday's final.

Chung is the youngest Grand Slam semi-finalist in eight years, …and the lowest-ranked Australian Open semi-finalist in 14 years.
The 21-year-old Korean has earned nearly 711-thousand U.S. dollars in prize money for reaching the semi-finals, …on top of some 40-thousand dollars for reaching the quarter finals. These amount to more than 40 percent of his accumulated prize money before the Australian Open.
If Chung wins the match with Federer, he will become the first Asian player to reach the men's finals in the Australian Open.
