Serena Williams... progress to the next round.Serena Williams... progress to the next round.

Tournament favourites Novak Djokovic and Serena Williams raced into the third round of the Australian Open and out of the heat yesterday as controversy over play continuing in scorching temperatures rumbled on for a second day.

Cloud cover and a gusty wind helped keep temperatures just below the peak of 42.2 degrees Celsius they reached on Tuesday, when Canadian Frank Dancevic passed out and accused organisers of forcing players to play in “inhumane” conditions.

Ivan Dodig became the 10th player to retire in the first three days of the tournament, though, when he was unable to complete his match against Bosnian Damir Dzumhur on one of the exposed outer courts at Melbourne Park.

“Today, 30 minutes after the match I could not walk,” Croatian Dodig told reporters.

“There were 10 people around me. I was thinking I could maybe even die here. I think we deserve that somebody listens to the voice of the players.”

Djokovic needed 107 minutes to take the second step on the path he hopes will take him to a fourth successive title by thrashing Argentine Leonardo Mayer 6-0 6-4 6-4 on Rod Laver Arena.

Williams also hot-footed it into the third round with a 6-1 6-2 demolition of Vesna Dolonc before revealing her own visualisation technique for keeping cool.

“I just pretend I’m in Hawaii riding a wave, that’s all I can do,” she said after setting up an encounter with Daniela Hantuchova who survived a gruelling battle against Karolina Pliskova, winning 12-10 in the deciding set.

Djokovic retired from a match against Andy Roddick in another Melbourne heatwave five years ago but proved against Mayer that he is an altogether stronger player than in 2009.

“You don’t want to spend too much time in the heat. You want to try to win as quick as possible,” the second seed, who next faces Denis Istomin, told reporters.

“I prepared myself mentally for that. It’s not just physically.”

Williams was her usual mix of elegance in her dress and brutality in her play as she dismissed Dolonc in just over an hour on the same court.

She has seen off at least a couple of generations of younger women looking to knock her off the top of the game and 16-year-old Swiss Belinda Bencic is tipped to be in the vanguard of the next wave.

The qualifier started poorly in her match against Li Na but after losing the first seven games, rallied to force the second set into a tiebreak before losing 6-0 7-6.

Two former grand slam champions, Ana Ivanovic and Samantha Stosur, had straightforward victories to set up a third round meeting tomorrow, when temperatures could hit 44 degrees Celsius.

Tomas Berdych, dressed in what looked like a blue and white striped Argentina soccer shirt was the first man into the third round when he hammered Frenchman Kenny De Schepper 6-4 6-1 6-3.

Berdych said conditions were the hottest he had played in and suggested that if the threshold for stopping matches had not been reached, it was probably set too high.
