Andy Murray reached the Paris Masters last eight with a 6-2 6-2 win against 2003 US Open champion Andy Roddick.
The British number one powered through the first set in 31 minutes before dominating his American opponent again in the second to seal the victory
For world number three Murray, it was a 27th win his last 28 appearances and extend his unbeaten run to 18 matches.
He next faces Tomas Berdych or Janko Tipsarevic, with Novak Djokovic and Roger Federer also playing on Thursday.
The only downside to Murray's win was a leg problem that forced him to call for the trainer early in the first set.
"Another thorough beating for Roddick, who must be sick of the sight of Murray. It was another thrashing, humbling, all those kind of words. The forehand was the real highlight for Murray. When he's in cruise control, he unwinds on that wing and it's great to watch. The half-volley winner from the baseline in the second set was the pick. Another classy performance."
"I felt my hamstring, similar to last week, and I just wanted to get it checked out," said the 24-year-old.
"I'll have to monitor it. Everyone has niggles at this stage of the season and you have to deal with them. I felt it early on, it might have been to do with the early start. Maybe I didn't warm up as well as I normally would."
Murray set the tone when he broke Roddick's serve in the first game before holding for 2-0 and then producing a stunning backhand en route to another break for 5-2.
The first set was secured with a sensational winner and things went from bad to worse for Roddick when Murray immediately broke his serve at the start of the second.
Roddick vented his frustration by smashing his racket and arguing with umpire Mohamed Lahyani, earning a code violation for racquet abuse, and Murray won the next two games for a 4-0 lead.
The 29-year-old from Texas managed to pick up a couple of games, but it was too little, too late as Murray unleashed his sixth and seventh aces to seal an emphatic triumph.
Murray was delighted with the manner in which he dispatched Roddick, despite the 0930 GMT start time.
"He's been number one in world, a Grand Slam champion, one of the best players in the last 10 years and always difficult to play against," continued the world number three.
"I started the match really well and got up an early break. He's a player who can build pressure by serving well and goes after you in return games, but because I made a good start I was able to dominate.
"The hardest thing about starting so early is that half and hour to 45 minutes before the match I was having to get pasta and fish down me.
"But you just wake up a bit earlier - it's one of the things with tennis, you never know when you're going to play. I have had to get used to it the more years I've been on tour, but it was a bit early today."
