Andy Murray routs Andy Roddick at Paris Masters

World number three Andy Murray powered into the quarter-finals of the Paris Masters with a comprehensive 6-2 6-2 win over Andy Roddick.

The 24-year-old Scot dominated throughout to record his 27th win his last 28 matches and extend his unbeaten run to 18 matches.

Murray comfortably claimed the first set in 31 minutes before easing through the second to clinch an impressive win.

The British number one set the tone when he broke Roddick's serve in the first game before holding his own serve.

He continued to apply pressure on the American's serve and produced a stunning backhand to earn three break points in game seven, and duly converted one to go 5-2 up.

Murray wrapped up the first set in style with a sensational winner as Roddick seemed to have few answers to the one-way traffic.

Things went from bad to worse for the American when Murray immediately broke his serve in the second set before holding serve in the second game.

Roddick vented his frustration to umpire Mohamed Lahyani by destroying his racket, earning a code violation for racket abuse as a result, as Murray won the next two games to take a 4-0 lead in the second set.

The 29-year-old from Texas then dug in and held serve to get himself on the scoreboard, but Murray hit back immediately with a hold to love to put himself on the brink of victory.

Roddick finally tested Murray en route to claiming his fourth game but it was too little, too late as Murray unleashed his sixth and seventh aces of the day to seal an emphatic straight-sets triumph.

Murray revealed his tactic was to get on top of Roddick and disrupt his powerful serve from the start.

"He's been one of the best players in the last 10 years and is always difficult to play against but I started the match very well and got up an early break," Murray told Sky Sports 2.

"He can build pressure by serving very well and tends to go more for the return games and today because I got off to that good start I was always in the lead and able to dictate the way the match went."

The Scot denied he was carrying an injury after he was forced to call for the trainer during the first set and insisted it was likely to be due to the early start.

"I just felt my hamstring similar to last week and I just wanted to get it checked out so it's something I will have to monitor.

"I think everyone has niggles at this stage of the season and you just have to try and get though them and make sure you're not doing any long-term damage but it felt fine afterwards.

"It might have been something to do with the early start and maybe I wasn't quite as warmed up as much as I would have been if I'd have played later."

The world number three also revealed the early start was a minor disruption to his preparations.

"The hardest thing is 45 mins to an hour before going on court I have to get pasta and fish down and fish at that time of the morning isn't great.

"That's why tennis is a bit challenging because you never know when you could play.

"It's something you get used to the more years you're on the tour but it's probably the earliest start I've had in six or seven years."
