Russian Mikhail Youzhny, 10th seed of the men's singles, was knocked out of the top 16 by quarlifier Milos Raonic from Canada at the Australian Open on Saturday.
The 28-year-old veteran lost to the Australian Open debutant 6-4, 7-5, 4-6, 6-4 in the third round, equalling his performance here last year.
It is the first time for Raonic, ranked 152 in the world, to reach the fourth round at a Grand Slam event in just his second appearance at a major.
