In the Australian Open Tennis Championships at Melbourne, Roger Federer will take on Chung Hyeon while Angelique Kerber and Simona Halep raced into a semi-final showdown. The clinical Swiss ace strode into the last four at Melbourne Park for a 14th time with a clinical 7-6 ,6-3, 6-4 dismantling of old foe Tomas Berdych. He now faces Chung Hyeon on Friday for a place in the final after the unseeded South Korean kept his dream run going by battling past American Tennys Sandgren 6-4, 7-6 , 6-3. Germany's Angelique Kerber swept aside Madison Keys of the United States 6-1, 6-2 and will go into her clash with the world number one. Top seed Simona Halep was equally impressive when she brushed aside sixth seed Karolina Pliskova 6-3, 6-2.
