Rafael Nadal beats Dominic Thiem to win 11th title at Roland Garros
World number one Rafael Nadal won an 11th French Open title by beating Austria's Dominic Thiem in straight sets
Nadal, 32, won 6-4 6-3 6-2 to earn his 17th Grand Slam, three adrift of Roger Federer's all-time men's record.
The Spaniard edged an intense opening set, tightening his grip in the second.
And he increased the tempo further, consigning Thiem to defeat in his first major final when the Austrian sent a return long.
Nadal is the only second player in history to win the same Grand Slam on 11 occasions after Margaret Court, who won 11 Australian Open titles between 1960 and 1973.
However, it was not all smooth for Nadal, who missed four match points on his own serve before clinching victory when Thiem went long on the fifth.
Nadal dropped his racquet at the baseline in celebration before turning to his box and raising both hands skywards.
The Spaniard had been the hot favourite to win the second Slam of the year, after warming up with three clay-court titles in Monte Carlo, Barcelona and Rome.
The Majorcan has an air of invincibility at Roland Garros, losing only twice in 87 matches since making his debut in 2005, and again he delivered on his favourite stage.
He had breezed through his opening four matches without dropping a set - extending his own personal best to 37 consecutive sets here - though falling short of Bjorn Borg's all-time record of 41 by losing the opener of his quarter-final against Diego Schwartzman.
That was about as disheartening as it got for the world number one.
Against seventh seed Thiem he was at his destructive best, using his athleticism and mental resilience to wear the Austrian down with his relentless shot-making.
Thiem, playing in his first Grand Slam final, simply had few answers to Nadal's brilliance.
Rafael Nadal needed treatment for what looked like cramp in the third set
Nadal had made slow starts to his service games in his semi-final against Juan Martin del Potro and Schwartzman, but imposed himself straight away against Thiem by holding to love in the opening game and backing it up with a break in the next.
Thiem did break back in the third game, but had to fend off more chances for Nadal on his own serve - particularly in a 13-minute sixth game - before the Spaniard struck in the final game of the set.
Nadal also stamped his authority early in the second set, breaking again at the first opportunity, as Thiem started to become frustrated.
The Austrian had a chance to break back for 4-3, but his opponent saw it off with a backhand down the line and closed out the set as the inevitable loomed.
Only one player had ever beaten Nadal from two sets down at a Grand Slam - Italian Fabio Fognini at the 2015 US Open.
Thiem never looked like becoming the second.
Nadal refused to ease off at the start of the third, missing five break points in two long service games for the Austrian, who eventually buckled with a wide forehand to trail 2-1.
Nadal broke again for a 5-2 lead, then served out - after suffering cramp in his left arm and missing those match points - to win in two hours and 42 minutes.
