Nadal is now the first player in the Open Era, male or female, to win 11 titles at three different tournaments, having also completed La Undécima at Monte Carlo and Barcelona in April this year.
Nadal's 11th title takes his grand slam tally to 17 and even at 32, despite the miles in his legs, who is going to stop him making it 12 in a year's time?
"Along with Nadal, he is literally still the world of men's tennis, and to not play a Grand Slam on a surface that we play for two months, on which everybody has grown up on, to not come to the showpiece of claycourt tennis, it hurts the tournament, it hurts professional tennis, it hurts men's tennis".
Either Federer or Nadal has captured each of the last six Grand Slam championships.
Nadal endured a nervy conclusion to the final, however, when he needed treatment in the fourth game of the third set for a finger injury before sealing victory on a fifth match point when Thiem fired a backhand long. At the following changeover, he was given a salt pill by a doctor and had his left forearm massaged by a trainer.

But it ultimately proved a futile mission as, just like in all but two of Nadal's previous 87 matches here, the incredible Spaniard proved invincible, winning 6-4 6-3 6-2. The Argentine ended Nadal's run of 37 consecutive sets in a rain-delayed quarter-final before the Spaniard won the contest upon the resumption on Thursday under glorious blue skies.
"I am sure you will win here in the next couple of years", Nadal told Thiem afterward. And of course, with it being on clay, Nadal is an overwhelming favorite.
But from the moment Nadal broke serve in the 10th game to win the opening set Thiem's belief ebbed away.
But the Austrian freed his shoulders and broke back in the third game with a forehand victor - pumping his fists in the direction of coach Gunter Bresnik.
It was more of the same in the second, as Nadal won the opening three games in quick time to take a commanding lead he would never relinquish.
Why? Nadal was 95-0 when capturing the opener on clay in the best of five format.
There was still fight in Thiem, though, and he had a break point when Nadal served at 4-2 ― a game in which the Spaniard was warned for taking too long to serve.
