Andy Murray raced into the quarterfinals of the Sony Ericsson Open in Miami with a 6-1 6-0 trouncing of Victor Troicki.

The British number one did not need to be anywhere near his best against the beleaguered Serbian as he wrapped up victory in less than an hour.

The 21-year-old will next face a rematch with Fernando Verdasco, who upset him in the Australian Open in January, after the Spaniard beat Radek Stepanek 6-2 6-2.

Murray had started slowly in his second and third-round matches but he sprung out of the traps today, breaking in Troicki's first service game.

The 23-year-old is at a career-high world ranking of 41 and is set to climb higher following his run in Florida, which included a second-round win over David Nalbandian.

Murray won their only previous meeting in straight sets on his way to the title in St Petersburg last year and the early stages today offered no indication there might be a different result.

Indeed, Troicki was struggling just to win points and two crunching returns from Murray helped him to a second successive break and a 4-0 lead.

The Scot had two points to wrap up a love set but, to his credit, Troicki came up with some big serves to finally get on the board after 27 minutes.

It was only a temporary reprieve, however, as Murray easily served out the set.

Troicki's main problem was his serve, with the Serbian's first-serve percentage down at 25% in the opening set and his second serve an invitation to his opponent.

The second set continued in the same vein with Murray again taking full advantage of Troicki's woes to break in the first game.

The Serbian battled hard to try to hold on to his serve but again he was unsuccessful as Murray eased to a 3-0 lead.

Troicki fought back from 0-40 to 30-40 in his next service game but another short second serve was a present for Murray and he duly served out for an easy victory.

Murray revealed he had gained confidence from his fast start and declared himself content with his performance.

He told Sky Sports: "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."
