The defending champion deposits the Australian tennis championship early ... and the end of the Egyptian champion's career

US world number four and defending champion Sophia Kenin called the Australian Open today, with a bitter defeat by Estonian Kaya Kanebi in the second round, while Australian top seed Ashley Barty crossed into the third round.

Kenin, 22, has struggled since arriving in Melbourne to live up to expectations, but Kanebe stripped her of the title in the second round when she was defeated by two straight sets 6-3 6-2.

On the other hand, Egyptian Mayar Sharif called the championship after special performances, against Slovenian Kaya Jovan 6-3, 7-6, and 6-3.

On the other hand, at the men's level, the Greek fifth seed, Stephanos Tsitsipas, survived a five-set marathon with Australian Thanassi Koukinakis, keeping his hopes for his first major title.
