Nadal found an extra gear to cruise to a comfortable 6-1 win in the deciding set.
And De Minaur had the chance to see first hand what it takes to make a top-10 player, with Nadal explaining how he had turned the match around.
“Well, you need to have the mind open and clear to find solutions, and I was not able to win many points on the return during all the second set,” Nadal said. “I needed to change something, and that’s what I did.
“I think I advanced my position around one metre, one metre and a half on the return, on the deuce especially, and I take the first point. And then game change, because then the pressure is on the other side of the court.
“So just tried to change a little bit the dynamic, tried to change a little bit the energy of the match in that moments and tried to make feel the opponent something different that is not going the same way that have been going for the last 30 minutes.
“So that’s what I tried. And today it worked.”
