On the eve of the Australian Open, the electric, sometimes eccentric tennis star has become the sport’s biggest draw, but he’s also its riskiest pitchman.
Karen Khachanov of Russia needed five sets to put Kyrgios away, 7-5, 4-6, 7-5, 6-7, 6-4. He will play Casper Rudd of Norway in the semifinals on Friday.
Medvedev grew frustrated in a four-set loss that ensured neither singles draws will have a repeat winner this year. Kyrgios will play another Russian, No. 27 Karen Khachanov, in the quarterfinals.
In case you missed it: The defending women’s champion, Emma Raducanu, is out, and the defending men’s champion, Daniil Medvedev, is set for a finals-worthy match with Nick Kyrgios.
