Australian Open officials have applied the extreme heat policy for the first time this week at Melbourne Park as the sport's biggest names wilted in the punishing conditions.
With temperatures consistently above 40 degrees in Melbourne for a third day, tournament referee Wayne McKewen opted to enforce the extreme heat rule today.
Several players wilted in the extreme conditions, with women’s world number 50 Varvara Lepchenko one of many forced to take a medical time out.
