Australian Open: Andy Murray Cruises Into Second Round (VIDEO, PHOTOS)

Andy Murray's form matched the weather as he scorched into the second round of the Australian Open with victory over Japan's Go Soeda.

It was just the fourth seed's third competitive match following back surgery in September but he took only an hour and 27 minutes to win 6-1 6-1 6-3. The result was in contrast to Monday's action when both of Britain's women, Heather Watson and Laura Robson, were knocked out.

The soaring temperature had been the main talking point on day two at Melbourne Park so to win so quickly was a major positive for the three-time runner-up.

The temperature was still above 40C when play began on Hisense Arena just after 5.30pm.

The full extreme heat policy had not been implemented despite the conditions, meaning the roof was open.

Given Murray's lack of match play following back surgery, the energy-sapping heat was certainly something he could have done without.

The Scot has seemed unsure himself how he will fare during best-of-five-set matches, but this was at least a gentle-looking opener.

Soeda, 29, is ranked only 112th in the world - down from a high of 47 in 2012 - and has no grand slam pedigree.

Murray received a huge cheer when he walked onto the court and was even treated to a rendition of Flower of Scotland.

Soeda served two aces in the opening game but from there he began to make errors in the face of consistent play from his opponent.

Murray reeled off five successive games despite playing within himself, although there was nothing wrong with the way he was hitting the ball, as he proved with one rasping forehand winner.

And when Soeda's serve came under pressure again, a double fault handed the set to the Scot.

The good news for both players was the court was completely in shade, which meant they were spared the full heat that had seen one player collapse and another be sick on court.

Murray was clearly a man in a hurry, and he upped the aggression in his play to lead 3-0 in the second, making it nine games in a row.

Soeda stopped the rot with a service hold but Murray broke again with his latest backhand winner and then won his service game to love to take the second set 6-1 after only 49 minutes.

Maintaining a consistent level is likely to be the area of Murray's game that takes the longest to come back following his lengthy lay-off.

The 26-year-old certainly did not play as well at the start of the third set but Soeda could not exert any real pressure on the Murray serve.

And it was no surprise when the Scot broke to lead 4-3, putting aside frustration at missing two break points by taking the third.

That proved the decisive moment as a limp attempted drop shot from Soeda that barely reached the net gave Murray victory on his first match point.

The world number four gave a small leap and punched the air, no doubt delighted to have passed the first test with such flying colours.
