Roger Federer ’very excited’ to play semi-final newcomer at Australian Open

Roger Federer is happy to see Kyle Edmund and Chung Hyeon make their breakthroughs at the Australian Open to bring fresh blood to the sport.
Chung defeated Tennys Sandren 6-4 7-6 (7/5) 6-3 to follow Edmund into the semi-finals at Melbourne Park. It is the first time for 10 years that an unseeded male player has made it to the semi-finals of a slam and the first time since 1999 that there have been two unseeded men through.
