This is the 6th time, he has dropped one or less than one set at French Open.
Sunday's win was Nadal's 17th major trophy, only putting him three behind Roger Federer.
But Nadal roared into the 2017 Australian Open final, losing to Federer, then captured his record 10th French Open crown in June previous year, setting the stage for another title run in the Flushing Meadows fortnight at the US Open in September.
Wawrinka, who has had to deal with a double knee surgery, has been playing intermittently in the 2018 season as he aims to get back into top gear.
The mayor said the plaque will be displayed in a yet-to-be-decided sports facility, and praised Nadal as both a human being and a champion.
Nadal will look to capture his 18th Grand Slam title next month at Wimbledon. "If you told seven or eight years ago that I will be here at 32 years old having this trophy with me again, I will tell you that is something nearly impossible, but here we are".
An already daunting task for Thiem, the Austrian seventh seed, got even harder when Nadal broke him in his first service game. Could he shock the world and defeat Nadal at Roland Garros? Nadal, 31, becomes the first man in history to win the same major 10 times. "I played a great match against a great player", said Nadal. I had a long and mentally tough clay court season because I played nearly all possible matches after coming from an injury. "You could nearly see the hand start cramping up as the fingers go stiff - it's a frightful feeling", Croft said.
"So I am not much anxious about the future".
Simona Halep is hoping her tough journey to a first Grand Slam title, that culminated with her lifting a historic Roland Garros trophy on Saturday can inspire the younger generation in Romania.
Nadal spent several months away from the tour after sustaining an injury at this years Australian Open and could, like Federer, decide that his long-term interests are best-served by sparing his body further punishment. Nadal -5.5 games is available on the Exchange at [1.68] and given the fact that Nadal has tended to dominate Thiem on non-quick clay, this should be a very likely outcome if Nadal wins the final.
But the biggest news from the ATP Rankings was the massive fall of multiple Grand Slam champions Andy Murray and Stan Wawrinka.
He led by two sets plus a break early in the third when the middle finger on his racket-wielding left hand was cramping so badly he couldn't straighten it. A clay court specialist who had made the semi-finals at Paris over the last two years, and the final this time around; someone who had beaten Nadal on clay three times in the past, though never in a five-setter.
