Federer brushes aside heat concerns

Australian Open organisers defended their heat policy on Friday as Roger Federer downplayed the oven-like conditions on court, saying players should be fit enough to deal with it.

The comments follow suffocating weather at Melbourne Park over the past two days, with some players struggling to cope as temperatures hit 40 degrees Celsius.

Novak Djokovic on Thursday described the conditions as "brutal", complaining it was hard to breathe and they were "right on the limit".

Organisers only activate the extreme heat policy and halt play or close roofs when the temperature exceeds 40 Celsius and the wet bulb globe temperature index hits 32.5 Celsius.

Tournament director Craig Tiley said the Australian Open was one of the only events in the world to actually have a heat policy.

"The policy is from consultation with the players, and remember in most places, be it the Middle East or others parts where it is very warm, they don't have a heat policy," he said.

"Throughout the site we have ice misters, there's plenty of water. For the players there's ice vests, there's longer periods of rest and they of course have shade on their chairs," he added.

"These are professional athletes. We are at the end of the day an outdoor event. We want it to stay an outdoor event as long as possible but at the same time ensuring that the health and wellbeing of players is taken care of."

Federer escaped the worst on Thursday, playing a night match on Rod Laver Arena, but said he had endured searing Australian temperatures plenty of times and experienced worse.

"If you want to get to the top, you've got to play in all conditions," he said.

"We know it can be very hot here in Australia. I remember the days when we had four days of 40 degrees in a row a few years back. Now we got two.

"It's definitely a challenge," he added. "It's hard to prepare for that in some ways. But you know when you come down here that can happen.

"Sure, I was watching the other players suffer. As long as nothing bad happens, it's all good."

On Friday, France's Alize Cornet had her blood pressure and pulse monitored by a doctor on court during a medical timeout.

She said she thought she was going to faint, labelling conditions "dangerous for the health of the player".

But she added: "I would never give up. I would need to be crawling on the court before I give up."

Federer said it was a tough call to make on whether to halt play or not.

"What do you do? You stop all matches?," he asked.

"The lucky guys on the big courts, they get to play under the roof. The other guys get postponed till the next day? Is that great? That's not great either."

He added that all the players knew these conditions could happen, and it was a level playing field.
