Murray eases into last eight in Dubai
The Scot looked rusty against Michael Berrer yesterday, shading a three-set contest in his first match on the ATP Tour since the Australian Open.
But he was far sharper against the world number 185, unleashing his full array of shots to wrap up the match in 82 minutes.
Swiss player Chiudinelli did not pose any problems on paper, and looked a distinct second-best in the opening set.
Murray showed plenty of attacking intent and hit some ferocious groundstrokes, breaking in the fourth game of the match and never looking like surrendering that advantage.
Despite the deficit, Chiudinelli proved a sterner challenge in the second set, taking Murray deeper on his own serve, and holding early on with relative comfort.
The Scot almost picked him off to break at 3-3, only to miss a break point and make a meal of a drop shot, with Chiudinelli executing the same shot with panache the very next point to take a close game.
But with Murray sensing an opportunity at the business end of the set, the Swiss could not hold him off again. With a combination of stout defensive work and vicious forehand winners, the 24-year-old earned the break to serve for the match.
Murray had not conceded a break point all match, and was clinical once again to reach the quarter-finals in Dubai for the third time in his career.
Berdych said his head-to-head record against the Scot, which he leads 3-1, counts for little.
"The statistics are one thing, and what's going to happen on court is the other one," said the world number seven.
