Women’s No 1 survives soaring temperature to defeat teenager 6-3, 6-0

Melbourne Park enacts extreme heat protocols on way to 45C

Aryna Sabalenka ended the teenage challenge at the Australian Open with an emphatic quarter-final final victory over Iva Jovic.

Having defeated 19-year-old Victoria Mboko in the fourth round, the world No 1 dropped just three games against 18-year-old American Jovic in a 6-3, 6-0 victory.

The scoreline was harsh on the youngster, who was very competitive in the points but time and again came out on the wrong end of games.
