Rafael Nadal was at his awe-inspiring best as he crushed Austrian Dominic Thiem to snatch a record-extending 11th French Open title with a 6-4 6-3 6-2 victory.

The Spanish world No 1 took his Roland Garros record to 86-2 as he captured his 17th Grand Slam title by demolishing the seventh seed, who was hoping to become the second Austrian to win the French Open.

In 11 finals in Paris, Nadal has only lost six sets as he matched the all-time record of most singles titles won at the same grand slam event set by Margaret Court at the Australian Open during the 1960s and 70s.

Sunday’s result marks the sixth consecutive slam won by either Nadal or 20-time major champion Roger Federer.

The muscular Spaniard had won all 10 of his previous Roland Garros finals and although Thiem was the only man to have beaten him on clay over the past two seasons, the Austrian never threatened the clay-court master on Sunday.

“I think today I played my best match of the tournament,” Nadal said.

“It was very important. Dominic is an opponent who is very aggressive, very difficult to play, with big shots.”

Nadal called on the trainer to get his forearms massaged twice in the final set but even that problem failed to improve Thiem’s chances of emulating fellow Austrian Thomas Muster’s 1995 triumph.

“It’s amazing now, I can’t describe my feelings,” Nadal told the crowd.

“It’s not even a dream to win here 11 times, because its impossible to think of something like this.”

Thiem was quick to praise his opponent’s incredible achievement.

“What you did and what you are doing is one of the most outstanding things an athlete ever achieved in sport, to win this tournament 11 times,” he said.

“Congrats. It’s amazing. Bravo.”

Nadal got off to a dream start, pocketing the first six points of the match as he broke Thiem in the second game to open up a 2-0 lead.

Thiem broke back immediately as he continued to go for his shots, and he saw off a break point to hold for 2-2.

Nadal, however, turned the screw in the 10th game and Thiem seemed to grow nervous, sending a forehand long to hand his opponent the opening set.

The top seed went 2-0 ahead in the second set as he wore Thiem down in lung-burning rallies, leaving the Austrian screaming in frustration.

Thiem found some life and threatened with a break point in the seventh game, but Nadal broke his pace with a drop shot and finished it off with a passing shot, holding for 5-2.

He bagged the second set when Thiem sent a backhand long.

Thiem was still on the back foot in the third set, being forced to save four break points in the first game. He dropped serve in the third and Nadal held for 3-1 after taking a time-out because of a sore hand.

He then had his forearm massaged at the changeover before resuming his demolition job. Nadal had another massage at 5-2 and ended Thiem’s ordeal on his fifth match point when the Austrian returned long.
