Britain's Andy Murray produced a late-night masterclass to nullify the threat of big-serving Milos Raonic and book his place in the US Open last eight.
Murray outclassed his 21-year-old opponent 6-4 6-4 6-2 in exactly two hours to reach his eighth consecutive Grand Slam quarter-final.
He enthralled the Arthur Ashe Stadium crowd and won just before rain arrived, having not faced any break points.
The Scot, 26, will face 12th seed Marin Cilic of Croatia on Wednesday.
"I used a lot of variation tonight," said Murray. "Milos has a huge game. I got lucky a couple of times but hit my passing shots very well.
"I had only played him one time before and you start to see things after a few games. I was just trying to react as quickly as possible.
"Sometimes the serves fly past you, sometimes you get a racquet on them and tonight I got a racquet on them. I tried to stay focused for every point and did a good job of that."
Murray looked exhausted in Saturday's third-round win over Feliciano Lopez, but any concerns about his condition were swiftly banished.
Raonic had won their only previous meeting - at April's Barcelona Open - and came into the match with 89 aces in the tournament.
Yet despite facing a flurry of huge deliveries early on, Murray soon got his eye in and registered a break point in game seven.
Raonic averted the danger on that occasion, but Murray struck at the next time of asking with a drop shot, before serving out an opening set in which he made only two unforced errors.
The British number one was turning defence into attack almost at will, while dominating from both the baseline and at the net.
Murray's superiority was illustrated in game two of the second set when he chased down a well-placed lob, swivelled and laced a crisp forehand winner past a stationary Raonic.
The breakthrough arrived in game five as Raonic aggressively saved two break points only to net a backhand on the third.
Murray swiftly extended his advantage and continued to impose himself in set three with a number of stunning passing shots.
After again finding the net on break point, Raonic looked a beaten man and Murray struck once more for 5-2 before comfortably serving out.
