(CNN) -- Andy Murray charged into the quarterfinals of the Sony Ericsson Open in Miami with a 6-1 6-0 demolition of Serbian Victor Troicki in just 58 minutes.
Murray needed less than an hour to reach the last eight of the tournament in Miami.
The British number now faces a rematch with Fernando Verdasco, who upset him in the Australian Open in January, after the Spaniard defeated Radek Stepanek 6-2 6-2.
Murray is adamant the defeat will not be preying on his mind as he bids to reach the last four.
The world number four told Sky Sports: "It's not like I'd be going for revenge or whatever, it's just another match. He's obviously played well this year."
Murray hardly broke sweat in his fourth round encounter and added: "I played well today. I concentrated hard and got my tactics spot on. It's nice to get off the court quickly.
"He didn't hit his first serve particularly well and I took confidence from my good start because I hadn't started that well in my last couple of matches.
"I started to hit my shots better and I was pleased with my short slice."
Serbian third seed Novak Djokovic also swept into the last eight with a straight sets win over Czech Tomas Berdych 6-3 6-2.
Djokovic will next face French 10th seed Jo-Wilfried Tsonga, who eliminated seventh-seeded countryman Gilles Simon 6-7 6-3 6-2.
Swiss second seed Roger Federer demolished American Taylor Dent 6-3 6-2 but world number one Rafael Nadal was made to work by Federer's compatriot Stanislas Wawrinka who finally succumbed 7-6 7-6.
American fifth seed Andy Roddick saw off French challenger Gael Monfils 7-6 6-4 and Juan Martin del Potro, the sixth-seeded Argentine, also made the quarterfinals by beating David Ferrer of Spain 6-3 6-2.
Eighth-seeded Svetlana Kuznetsova of Russia was first into the women's semifinals with a 6-4 6-7 6-1 win over Denmark's Caroline Wozniacki.
She was followed by Victoria Azarenka of Belarus who enjoyed a quickfire 6-1 6-0 victory over Australian Samantha Stosur.
Kuznetsova and world number five Vera Zvonareva will lead Russia in the Fed Cup semifinal against Italy in Nova Yardinia, Italy, on April 25-26.
Captain Shamil Tarpishchev also named Nadia Petrova, who is ninth in the world, Anna Chakvetadze, currently 23rd in WTA rankings, Alisa Kleibanova, Anastasia Pavlyuchenkova and Yekaterins Makarova in the squad.
The Czech Republic plays the United States in the other semifinal in Brno.
