Carlos Alcaraz fulfilled his potential as a future Grand Slam champion and world number one by winning the US Open title.
He won his first major title.
The 19-year-old is the youngest man to win a Grand Slam.
If he had won, he would have been the new world number one.
The first teenager to climb to the top of the rankings in the 49-year history of the rankings is Alcaraz.
After hitting a routine forehand long on his first championship point, Alcaraz took his second with a service winner out wide and immediately fell down in celebration.
After saving two set points in the third, Alcaraz ran up to his team in the stands and danced with them in a huddle before returning to his seat.
Since I was a child, I dreamed of being number one in the world and a champion of a Grand Slam.
I've worked very hard for it. It is truly special.
Alcaraz has been tipped for greatness since he was a child.
He has developed under the guidance of former world number one Juan Carlos Ferrero and has taken his game to a new level this season.
One of the biggest stages in the sport has been reached by Alcaraz.
Over the past fortnight he has shown his talent and heart to win over legions of new fans, demonstrating why he is considered by many the player best placed to replace Nadal, Novak, and Roger at the top of the men's game in the future.
Since Pete Sampras won here in 1990, the youngest US Open men's finalist has been Alcaraz.
He looked unburdened by the weight of history over the course of the three hour win.
The pair played to a high level throughout the match, with Alcaraz playing the bigger points better in front of a large crowd.
The difference in the first set was a single early break, which gave a strong platform to Alcaraz, who had won his previous 21 matches at a major after taking the first set.
Alcaraz had to fight in the third set after he showed signs of frustration.
Alcaraz, who had won three epic five-set matches in a row to reach the final, looked to be lacking energy on certain shots, but his opponent stopped him going ahead.
The Spaniard broke for a 4-2 lead and went on to win the match.
There's more to come.
