Marin Cilic dismantled an out-of-sorts Tomas Berdych in straight sets to reach the semi-finals of the US Open.
Cilic, the 14th seed, dominated on his own serve and was aided by a string of Berdych errors to win 6-2 6-4 7-6 (7-4) in two hours and four minutes.
The Croat, 25, into the last four of a major for the second time, now faces five-time champion Roger Federer.
Berdych, the sixth seed from the Czech Republic, said: "It was horrible from the beginning."
The 28-year-old had been broken only four times in the tournament prior to the quarter-finals, but struggled with the windy conditions to surrender his serve in the very first game of the match thanks to two double faults.
A second break was immediately recouped, but when another double fault saw Berdych lose his serve once more, Cilic sealed the set with a third ace.
That would be a sign of things to come for Berdych, as the Cilic serve dominated the second set.
The world number 16, who missed last year's tournament because of a drugs ban, won all but one of the 17 points when he landed his first serve, capitalising on a solitary break earned in the opening game.
Berdych looked to be mounting a fightback - earning a break early in the third - but was angered when the umpire rightly ruled he had failed to return a Cilic backhand before the ball bounced twice.
Following in the footsteps
Marin Cilic is bidding to become only the second man from Croatia to win a Grand Slam singles crown after his coach Goran Ivanisevic, who triumphed at Wimbledon in 2001.
From 30-15 up, Berdych was broken and was unable to make another impact on the Cilic serve, as the Croat took the match on a tie-break to reach his first Grand Slam semi-final since the 2010 Australian Open.
"It was a truly amazing day for me," said Cilic. "It was very gutsy in difficult conditions.
"I adjusted better than Tomas and I could rely on my serve. I played pretty good tactically and I am pretty happy with everything."
"I've had tough times over the last couple of years and I'm really happy that things are working out. I'm enjoying my time on the court."

Quotes of the day
"Are you serious or have you spent too much time in the sun? Have you ever had a racquet in your hand? You should get at least a penalty for such a call like this. It's a terrible call. It's impossible you have two bounces on a shot like this. You never have a clue about tennis." Tomas Berdych gets hot under the collar about the umpire's correct call on a double bounce.
"I think it's something which I was thinking about definitely. I think just needs probably the right time and timing to make it happen. Let's see. I hope for the time is going to come up. Fingers crossed." Once he calmed down, Berdych admitted he may work with Andy Murray's former coach Ivan Lendl.
"It's special, but I'm not thinking all the time I'm in a Grand Slam against Serena." Ekaterina Makarova, who has also reached the women's double semi-finals, is not all consumed by her singles semi against Serena Williams.
"It's so easy now because it's almost a joke for me because I have done little to no winning in the majors. And I thought, 'Take it as a joke. Oh my God, I'm past the fourth round. Woo'. I'd better play doubles just in case I don't make it past the second round. At least I have a back-up plan." Serena Williams takes a relaxed approach to her meeting with Makarova.
"I talk with her more in Spanish than in Italian because she's boyfriend is from Spain. (Martina slaps Flavia.)" The official transcript for Flavia Pennetta and Martina Hingis raises more questions than answers.
"You know Goran, so Goran is everything but not boring." Marin Cilic assures us that coaching has not changed Goran Ivanisevic.
