Second seed Roger Federer powered to a 6-4, 6-3, 6-2 win over Roberto Bautista on Tuesday, charging into the quarter-finals of the US Open for the 10th time in 11 years.
The 26-year-old Spaniard was handed the unenviable task of trying to upset the 17-time grand slam winner on Arthur Ashe Stadium court, where the Swiss maestro has a dazzling 25-1 record under the Flushing Meadows floodlights.
It quickly became clear there would be no power shortage on Tuesday as Federer raced to a 5-1 lead in opening set then eased off the gas and coasted to an unflustered win in just under two hours.
Next up for the five-time US Open champion is in-form Frenchman Gael Monfils, who earlier surprised seventh seeded Bulgarian Grigor Dimitrov and has yet to drop a set on his way to the last eight.
Dominant Berdych crushes Austria's Thiem to reach quarters
Czech Tomas Berdych put Austrian youngster Dominic Thiem firmly in his place at the US Open as he romped into the quarter-finals with a 6-1, 6-2, 6-4 victory.
The sixth seed raced through the first set and needed just one hour, 38 minutes to take his place in the last eight at Flushing Meadows for only the second time in his career.
Thiem, who turns 21 on Wednesday, had beaten Ernests Gulbis and Feliciano Lopez on his way to the fourth round of a grand slam for the first time but was outgunned by Berdych in all departments.
"I’m very happy with today's win," Berdych said. "I'd like to point out one thing which was the key, when I was 0-40 down in the first game on serve, and I saved it.
"That was a nice boost in the beginning and from then on I played well. Everything worked today, job done, that's good."
In the quarter-finals, Berdych will play Croatia's Marin Cilic, who earlier edged out Gilles Simon of France in five sets.
