Murray was looking to build momentum leading up to the first major of the year after impressing in his opening win against James Duckworth.
"It's been really hard".
"So I'm happy I'm back out here again".
"I want to try and enjoy playing tennis as much as I can, I don't know how long it's going to last, but we'll see".
He appeared stiff and rusty to start the match but managed to chase down Duckworth's chips and drop shots and moved across court well, twice manufacturing forehand winners from defensive positions on important points.
Murray is dealing with regular pain but said it didn't hamper his shot-making or movement during the match.
"I don't feel apprehensive about my hip today, whereas when I was playing again in kind of June, July previous year, my hip was pretty sore", he said. Today I felt like I saw the ball better versus, say, the middle of a year ago. "And some people think that we as tennis players, we play too much, but also our body gets used to competing week in, week out and playing lots of matches and that kind of becomes our norm".
Andy Murray cut short his season last September after suffering pain in his hip following surgery.
"I think for a first match of the new year after quite a long break it was all right", the 31-year-old said.
"The first three games took about half an hour, so there was very little in it, especially in that first set at the beginning", Konta said. "After all I suffered past year in terms of injuries, I don't want to do mistakes in terms of playing without being 100 percent".
He has been replaced in the draw by lucky loser Taro Daniel of Japan, who will play Jo-Wilfried Tsonga on Thursday.
U.S. Open champion Naomi Osaka said she felt nervous but kept her cool to beat big-hitting Australian teenager Destanee Aiava 6-3, 6-2 to reach the quarterfinals in a positive opener to her season. His opponent was Russian player, Daniil Medvedev, who beat him 7-5, 6-2.
Chardy came back from losing the first set to beat Australian Nick Kyrgios 6-7 (5/7), 6-2, 6-3.
Medvedev was always likely to prove a stronger test of his credentials with the Australian Open just two weeks away, and so it proved as the young Russian overpowered the three-time Grand Slam victor.
"The most important thing is to keep moving forward", she said.
"I was just trying to hang in there in the second set".
