Murray, a wildcard for the competition in Spain, won 2-6 7-5 7-6. (7-3).
In the last eight, the British number three will compete against the American Sebastian Korda.
Murray remarked, “I believe I served better in the second and third sets, but I also just battled really hard.”
“In the first set, I wasn’t at my best, Pedro served well throughout the first set and a half, and I had a lot of trouble breaking his serve.
I made a slight adjustment to how I was returning, gave myself more chances to break, and worked hard to recover from break deficits twice in the third set.
Murray, a former world number one, is participating in his first competition since the Laver Cup in September.
He had to fight hard for this victory since Cachin, rated 61st in the world, converted two of his three break points in the opening set despite him missing five of his own.
Murray got better in the second set before losing his service twice in the third, but he broke back each time and won the crucial tie-break.
Following the postponement of the ATP Tour’s China leg due to continued Covid-19 restrictions. Gijon is one of the six one-year sanctioned events playing this season.
