Andy Murray sailed through to the third round of the Western & Southern Open in Cincinnati after a 6-2 6-3 win over Mikhail Youzhny.
The Wimbledon champion was shocked in the last 16 of the Rogers Cup by Ernests Gulbis a week ago but looked much sharper this time as he wrapped up victory in an hour and 10 minutes.
Youzhny, who had defeated Gulbis to set up the contest with Murray, never threatened to make the match competitive, committing a string of unforced errors and dropping serve five times.
"It was an important match for me to get through because obviously I want to try and get as many matches as possible this week before the US Open," Murray told Sky Sports.
"I only got a couple last week so I was a little bit nervous before the start of the match because it was pretty important.
"I didn't make too many mistakes, I just tried to play a solid match and tried to find a way to win and hopefully feel better tomorrow (Thursday)."
He added: "I would have like to have hit a few more winners, I came to the net a few times and missed a couple of volleys.
"But I got myself in good positions, I wasn't going for huge shots, I was just playing high-percentage tennis to try and get the win.
"I'm going to have to try and play a little bit more aggressively and try to hit a few more winners as the matches go on."
Murray, champion in Cincinnati in 2008 and 2011, will next face France's Julien Benneteau as he continues his preparations for the defence of his US Open title.
The opening set against Youzhny was a largely one-sided affair in which Murray raced into a 4-0 lead, although the Russian did hold his own in some long rallies.
The world No 25 did not get on the scoreboard until game five, by which point the damage had already been done and Murray held on comfortably to move a set ahead.
Youzhny continued to struggle on serve at the start of the second and gifted a break to Murray with the latest in a series of wayward forehands.
It was no surprise when the Brit broke again to take a 4-1 lead and, although he was unexpectedly broken back straightaway, he completed the win soon afterwards.
