He entered the tournament knowing that his wife, Kim Sears, was around eight months pregnant. If he wasn't preoccupied with the upcoming birth of his first child -- due in the second week of February -- tennis certainly wasn't the lone thing in the 28-year-old's thoughts.
Then almost exactly a week ago, his father-in-law and Sears' father Nigel collapsed while coaching Ana Ivanovic as Murray competed on an adjacent court.
He raced to the hospital after the victory over Joao Sousa and again the next morning, throwing his tennis routine into chaos. He almost pulled out of the year's first major.
Sears, thankfully, was well enough to return home to the UK.
So Murray stuck it out and got what he wanted Friday: A spot in Sunday's showpiece.
Whether he can finally oust Novak Djokovic in a huge match -- the Serb won six of their seven meetings in 2015 and has toppled Murray in three Australian Open finals -- is another matter.
"I have a very good shot on Sunday if I play my best tennis," Murray told reporters. "I need to do it for long enough to have a chance. I'm aware of that. I don't think many people are expecting me to win on Sunday.
"I have to just believe in myself, have a solid game plan, and hopefully execute it and play well."
Murray will first need to absorb and recover from the four-hour semifinal against Raonic, who was so close to becoming the first Canadian man to make a grand slam singles final.
A right leg injury to Raonic visibly hampered the 25-year-old and Murray, who prides himself on his fitness, ruthlessly took advantage. Raonic was left visibly deflated.
"Probably the most heartbroken I felt on court," Raonic told reporters.
"It's infuriating for the tournament to end on this note and to have to face this knot in my stomach," he added on Instagram. "But it's not the end. Not by any means. I am better than that and I will overcome the challenges my body presents to me, I work far too damn hard and commit every waking moment to tennis."
So instead of making history for Canada, Murray and older brother Jamie have become the first siblings to land in the men's singles final and doubles final, respectively, at the same grand slam in the Open Era.
Murray's left-handed sibling, along with Brazil's Bruno Soares, will, somewhat ironically, get a Canadian in the final in veteran Daniel Nestor. Nestor's partner is the Czech Radek Stepanek.
Raonic is known as the "missile" due to his devastating serve, which thus puts him at the head of the queue when considering the game's next generation of stars. His ground game has also improved, reflected by his success over the last fortnight in reaching a second grand slam semifinal.
It was clear he was intent to be the aggressor against Murray. Overall Raonic struck 72 winners. Murray had 38.
But raggedness accompanied the aggression and Raonic made 78 unforced errors compared to Murray's 28.
The leg injury, which Raonic said began t
