The two-time Grand Slam champion made it through to the fourth round for the sixth time after an overpowering 6-4 6-2 6-3 victory, but also nuanced hitting against Kyrgios, who was hampered by an ailing right forearm.
After the early morning match on Court Suzanne Lenglen the 20-year-old Canberra star has some complimentary words for Murray, who is yet to drop a set in any of the pair’s three meetings.
“Murray is one of the best defenders in the game at the moment,” said the world No 30.
“He’s a freak athlete. He’s strong, I think that’s how he gets his advantage when he plays.
“He gets to so many balls, mixes it up well, great feel and great slice.
“He can get rhythm on his serve and return. He’s got many things that are good.”
Kyrgios’ elbow had been troubling him before Roland Garros after he was forced to retire during a match against Dominic Thiem in Nice earlier this month.
He plans to play the Topshelf Open in Holland and then Queen’s before Wimbledon, but he admits his fitness is an issue.
“Today I wasn’t near 100 per cent,” Kyrgios said.
“It’s surprising, really. I have done so much and it’s pretty heartbreaking going out there and something like that holding you back.”
