Roger Federer has backed tournament officials to leave the Rod Laver Arena roof open despite searing temperatures at the Australian Open.
With the temperature hovering around 40 degrees Celsius for much of day two, there was speculation play would be suspended on the outside courts and the roof closed on the main courts.
But play continued and the roof at Rod Laver Arena remained open as Federer cruised past Australian James Duckworth 6-4 6-4 6-2 and he was glad the roof wasn't closed.
"I think it should always stay open, honestly. That's my opinion," he said.
"I thought it was very dry, just hot, you know, stinging sort of sun.
"I guess also it depends on who you play, if you're playing a big server, clearly faster conditions. If you're getting into rallies, I guess you'll feel the heat a bit more.
"Depending on where you come from it has a bigger effect on you, this type of heat, then maybe humid heat. So it's very personal, and it can become just a very mental thing, you know, and you just can't accept that it's hot.
"Just deal with it, because it's the same for both. That's basically it."
Federer's win on Tuesday was not his best performance as he struggled for consistency from the back of the court against a player he had never met before, although he did serve incredibly well throughout the match and faced just one break point.
"It was okay. It was not much rhythm out there. It was a matter of getting the job done and not getting broken," he said.
"So it was a solid match from start to finish, yeah. Could have maybe won a few more break points here and there, but who cares now?"
Sixth seed Federer is playing the Australian Open at his lowest ranking since 2003 as he enters the twilight of his glittering career.
But despite being written off by most, Federer could not be happier with his preparation for the year ahead and is up for the challenge.
"Feel good. I'm excited," he said.
"I'm looking into the future. I have worked hard, put in the hard work, so from that standpoint there's no regrets right there.
"I feel good, and it's about for me, I want to prove to myself that I can bring it every match. I'm really excited. It's a tough draw, but I'm open for it and I'm ready to go.
"I'm happy I managed to beat the heat easily today, and I've entered the tournament, which is most important, first week as a whole. Hopefully I can move on from there."
