After five hours and 45 minutes, the longest match of Murray's Hall of Famer career, the 35-year-old held his arms aloft 4-6, 6-7 (4), 7-6 (5), 6-3, 7-5 at just after 4am local time!
"Unbelievable that I managed to turn that round," said an exhausted Murray.
"I'm aware I don't look particularly happy when playing but I'm at my happiest on the inside.
"I've always loved competing and always showed my emotions when I've played. I've been criticised a lot for it over the years but thats who I am."
Next up. You couldn't write this script, a 2019 Australian Open rematch with Roberto Bautista Agut.
