Into his 25th major semi-final, Nadal is the only the fifth man in history to reach 10 semis at a single grand slam event.
The Serb then also held all four Majors and became the first man to break the US$100 million (S$138m) prize money barrier.
"It looked in the third set like he just didn't want to be out there, couldn't compete any more, and that's shocking for a guy that's won as much as he has and prides himself on competition", added McEnroe.
"It was just not there for me today". He wound up with almost twice as many unforced errors, 35, as winners, 18. His backhand was particularly problematic. I lost that crucial break in the beginning of the second, and he started serving better, backing it up with the first shot. Djokovic was left on his knees, and soon he would be out of the tournament entirely. Their last meeting on that surface was in last year's French Open semifinals, a four-set win for Murray.
Still, how unlikely was this result?
After the defeat, Djokovic was accused of "tanking" by several analysts and commentators covering the 2017 French Open. "I don't know how many games I lost this year, but I really don't care about this".
Top-ranked Andy Murray was bemused by the chair umpire's decision to give him a time violation when he was preparing to serve during his French Open quarterfinal win against Kei Nishikori. "I have lived on that wave of excitement, I guess, 'til the U.S. Open or so".

As if by stealth, Dominic Thiem moved into the quarter-finals of the French Open on Sunday with another quietly devastating performance.
The Djokovic-Thiem victor will face Rafael Nadal in the semifinals.
"Thiem is a tough player", he said. No. 7 Marin Cilic.
Carreno Busta received treatment for an abdominal problem at the end of the first set before calling it a day with Nadal leading 6-2 2-0.
Perhaps Carreno Busta's almost four-and-a-half hour win over 2016 Wimbledon finalist Milos Raonic in the fourth round took a toll. I won in Barcelona and Madrid and I lost to him in Rome. I'm as motivated as any other player on the tour.
