The 29-year-old Spaniard, the oldest of the men’s quarterfinalists, had looked down and out when his Canadian opponent served him a bagel in the fourth set.
However, after getting some treatment to his lower back, 2017 semifinalist Carreno Busta fought back gamely to seal the deciding set in a match that lasted over four hours.
The 20th seed, who is eyeing a place in his maiden Grand Slam final, will face Alexander Zverev in the last four after the German took down Borna Coric 1-6, 7-6 (5), 7-6 (1), 6-3 earlier on Tuesday.
