Nadal gains De Minaur revenge in Madrid
Nadal's farewell tour has pitted him against De Minaur twice in as many weeks but this time the result was reversed as the 22-time Grand Slam champion advanced to a third-round meeting with Argentina's Pedro Cachin.
In front of a capacity crowd that included the King of Spain, French football icon Zinedine Zidane, and Real Madrid winger Vinicius Junior, Nadal dug deep to dismiss the world number 11, despite admitting ahead of the tournament he was still struggling with numerous physical issues.
It was an impressive performance from the 37-year-old but he immediately dismissed the idea it was anywhere near his vintage form.
"No, not yet. It needs time," said Nadal on court.
"I think for moments had been a good level of tennis, I've been able to do some positive things, but on and off. To play over two hours means a lot to me and the atmosphere here is just a joke.
"I really believe that tennis hasn't been an issue for the last two years, more the physical issues. If I'm able to play weeks in a row, then I can see how competitive I can be. That's not the case yet. Just step by step and let's see how I recover."
Five-time Madrid champion Nadal inched ahead 2-0 early on but lost his advantage in controversial manner as chair umpire Fergus Murphy refused to let the Spaniard challenge a ball from De Minaur that was incorrectly deemed in.
Murphy said that Nadal hadn't clearly indicated his intention to challenge while Nadal argued that he had completely stopped and circled the mark with his racquet, which he believed was enough to trigger a challenge.
Despite Nadal's protests, and his request to speak to the supervisor, Murphy would not relent and De Minaur's long ball was deemed in as the Australian went on to break back and draw level.
The pair traded breaks once more before entering a tiebreak, which Nadal sped to a 6-2 lead. De Minaur saved four consecutive set points but Nadal converted his fifth opportunity to take the opening set after one hour and 16 minutes of play.
The second frame began with a break of serve that went Nadal's way and he was soon up 3-1.
De Minaur battled hard but couldn't create any break point opportunities on Nadal's serve and the match ended on a double fault from the Australian, his 33rd unforced error of the contest.
