Dejected but gracious in defeat, Thiem told Nadal and the Philippe Chatrier court that his extended record for the most men's Grand Slam wins at any tournament was "one of the most awesome things in sport".
Rafael Nadal once again proved why he is called the King of Clay as he extended his record at the French Open on Sunday.
For Thiem, playing in his first Slam final, it was a tremendous letdown for a player who is the only man to have beaten the Spaniard on clay in the last two years.
Rafal Nadal admits he harbours ambitions of catching Roger Federer's Grand Slam haul but insists he's not obsessed in his pursuit of the 36-year-old's trophy total. I played my best match of the tournament, it's unbelievable and I'm very happy'.
- Nadal claimed his sixth French Open to equal the record of Borg, also taking his Slam total into double figures at 10. At the following changeover, he was given a salt pill by a doctor and had his left forearm massaged by a trainer. Not much more of a daunting task than doing so against this particular opponent at the French Open, where Nadal is now 11-0 in finals and 86-2 overall.
Nadal's career title count, which is now fourth on the all-time list, behind Jimmy Connors (109), Federer (97), and Ivan Lendl (94), and ahead of John McEnroe (77), whose tally he equalled and then surpassed with titles this year in Barcelona and Rome, respectively.
Thiem stayed with Nadal in the early going on a cloudy and steamy afternoon; the temperature was 24 degrees Celsius, the humidity approached 70 per cent.
"I still remember when you won here the first time in 2005". Maybe, just maybe, fans could get an entertaining French Open final-something that has been sorely lacking in this era of Nadal's absolute dominance.
Thiem was under the cosh, saving four break points in the first game of the third set before Nadal inevitably broke for 2-1. After guzzling water during that break, Nadal felt better and was back to playing his unmistakable brand of almost unbeatable clay-court tennis.
Thiem was still on the back foot in the third set, being forced to save four break points in the first game.
Whatever the problem, his dominance remained and a love game took him to 4-2 before he eventually sealed victory on a fifth match point when the Austrian fired another backhand long.
He became the first player to hold three major titles on three different surfaces at the same time when he won the Australian Open with a five-set success against Federer again.

However, it was not all smooth sailing for Nadal on Sunday, as he started suffering cramps on his left hand in the third set. After Nadal held there for 5-4, Thiem basically handed over the next game - and the set - by making four mistakes in a row.
