Andy made short work of American Sam Querrey, winning 6-4 6-2 6-4 in one hour and 59 minutes.

Querrey was the man who upset then world number one Novak Djokovic at Wimbledon last summer, but Murray made sure he did not fall victim to another shock after the Serb’s surprise defeat by Denis Istomin on Thursday.

Querrey gave the Brit plenty to think about in the early stages of their third-round match, attacking the net and hurrying the top seed, but a first-serve percentage of just 57% was not enough to keep Murray at bay.

The American missed a fleeting chance with a break point in game eight and Murray immediately took advantage, getting the break himself in the next game with a beautiful lob.

He took a firm grip on the match with a run of six out of seven games, easing through the second set with two more breaks.

There was a flurry of resistance as Querrey reeled off three straight games to lead 3-2 in the third set, but Murray once again turned up the pressure with his return to break for a fifth time on his way to a comprehensive victory.

“Sam, especially in the first set, was hitting a huge ball,” added Murray, who had no problem with the ankle he turned during his previous match.

“There was a key moment at 3-4 when I saved a break point and then managed to break the next game and had the momentum after that.”

Andy will now face Mischa Zverev in round four.
