Revenge won't motivate Murray

Andy Murray insists he will not be gunning for revenge when he meets Fernando Verdasco in the quarter-finals of the Sony Ericsson Open in Miami.

The British number one cruised into the last eight with a 6-1 6-0 demolition of Victor Troicki, while Verdasco was similarly impressive in defeating Radek Stepanek 6-2 6-2.

Murray won all of his first five meetings against the Spaniard but the sixth came in the fourth round of the Australian Open in January and this time Verdasco edged a five-setter.

The British number one was the form player at the start of the season and had been tipped to win his first grand slam in Melbourne.

But, despite that disappointment, Murray is adamant the defeat will not be preying on his mind as he bids to reach the semi-finals.

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."

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

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

Murray won their only previous meeting in straight sets on his way to the title in St Petersburg last year and the early stages 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.

The 21-year-old revealed he had gained confidence from his fast start and declared himself content with his performance.

He said: "I played well. 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."
