"I have felt OK the last few days and the adrenaline you feel by playing a match numbs any pain you may have", said the British star after seeing off world number 134 Bublik who was making his grass-court debut.
Bublik threw in a tweener - a between-the-legs shot with his back to the net - he threw his body around the court a la Boris Becker and even threw in a few comical grunts that drew laughter from the Centre Court crowd.
Crucially, the Scot said his injury has started to feel better after lengthy treatment and prolonged periods of rest over the last week.
"Once you get out there, I don't feel like I'm coming in trying to defend something". The mercurial Aussie, seeded 20, lost the first two sets of his opening round contest against Frenchman Pierre-Hugues Herbert, better known for his exploits on the doubles court, before calling a halt to the opening round clash. It's just been very sore the last few weeks. "Things can happen obviously when you're playing, players have got injured during tournaments".
Asked if she was excited by the opening day, she told Press Association Sport: "I'm more edgy actually. Considering how I was feeling five, six days ago, it was really positive".
When he arrived in Paris for the French Open, Murray was in a similar state of disarray: his form was in tatters, his confidence was ragged and, to make matters worse, he had a stinking cold.
Rain at the start of the third delayed Murray's passage but by then, he had broken again to snuff out any threat of a comeback.
On clay courts, with my serve, I'm not very well prepared yet. "It's a little bit sore but I was moving really good today".
"He said, "Yeah, I think I'm only on about 10 right now".
I think it was the best decision for me - not to have any compromise.
"It's just a little bit stressful".
Murray saw out the third set and can now prepare for a second round meeting with German entertainer Dustin Brown on Wednesday. We message each other from time to time. He's unpredictable. He's not easy to play against and he's had big wins here in the past. All tickets are already sold and I am sure that this action is going to be exciting. Andy's one of the best players in the first week at Wimbledon, so I don't worry too much for him there.
