After matching Murray for 40 minutes, Kyrgios' challenge faded quickly under sustained pressure from the Scot. Murray, the 2013 champion, is into the last eight without dropping a set. The 29-year-old has now won eight matches in a row on grass, and joins Pete Sampras and John McEnroe in reaching nine consecutive Wimbledon quarter-finals. Murray had beaten Kyrgios at the other three Grand Slams - and he brushed aside any thought this might be the Australian's time with a brilliant display. The world number two was focused throughout, winning 80% of points on the Kyrgios second serve and denying the 21-year-old a single break point. "The first set was very tight. I managed to get the break at 6-5 but it was tight up to that point," Murray told BBC Sport. "The second set was much more comfortable, Nick lost his focus a bit. I was able to dictate a lot of the rallies." Asked about the growing expectation of a second title following top seed Novak Djokovic's defeat on Saturday, Murray added: "Every year I play here it's the same. "I try my best to win my matches and go as deep as possible. "The matches, as you progress, get tougher. Tsonga is next who is a tough grass-court player and I'll have to play very well to win that one." Kyrgios said: "As soon as I lost the first set, I just lost belief. It obviously felt like a mountain to climb after losing the first. "He played pretty well, as well. I don't think he missed too many balls either." It is a measure of how sharp Murray is looking that he won the opening set despite Kyrgios making 30 of 34 first serves - the bedrock of his game. There were flashes of brilliance all over the court from the Australian and a tie-break appeared inevitable after 11 games without a break point, but Murray grabbed the initiative with a brilliant return game. A backhand pass gave the Scot a 0-30 lead before a clever cross-court chip drew a loose volley from Kyrgios, who suddenly found himself staring at three set points. Two were saved with big serves but Murray drilled a cross-court forehand on the third that Kyrgios could only divert into the net. If the first set was a tight, tense contest, the second disappeared in just 26 minutes as Murray maintained the quality of a tournament favourite, while Kyrgios' belief appeared to drain away. Murray was now peppering the baseline with his returns, drawing Kyrgios into rallies, and he made the breakthrough with another pass that the Australian could only net. Two games later and the pair's much-discussed friendship appeared briefly on hold as Murray slowed the quick-fire Kyrgios serving pace, prompting the Australian to thrash a wild forehand out and hand over another break. Murray crunched down his sixth ace to clinch a two-set
summary: Andy Murray saw off the threat of Australian rising star Nick Kyrgios with a clinical performance to reach his ninth Wimbledon quarter-final.
