World number two Andy Murray produced a master class in tennis as he cruised past Bulgarian Grigor Dimitrov in the round of 16 of the 2016 US Open on Monday. The Scot, who struggled in his third round clash on Saturday, was back to his imperious best. He thrashed his opponent 6-1, 6-2, 6-2 in a game that lasted just over two hours.

Murray knew that the Bulgarian would come into this game full of confidence with Dimitrov winning the last time they met at the Miami Masters, but he was confident of his game and admitted he played a very good match.

"I played extremely well, tactically I played a good match. It's definitely up there, I played well today, made very few unforced errors and made it tough for Grigor," Murray said, as quoted by BBC.

The 29-year-old who was broken only once in the entire game, delivered the fastest serve of his career at 141mph, which simply blew Dimitrov away. The British number one has now reached the last eight in 22 out of his last 23 Grand Slams.

"I served one at 145 in San Jose but the next day they recalibrated the gun because it was completely wrong. Tonight was the fastest serve I've ever hit. The other one was here at the US Open, 138. I think I was lucky. I only did it once. I'm not expecting to do it again", the world number two added.
