Canada's Denis Shapovalov overcame a slow start to be crowned boys' champion.
Shapovalov defeated Australia's Alex De Minaur in three sets after a bold comeback, winning 4-6, 6-1, 6-3.
In the first set Shapovalov showed his raw ability and power with big ground strokes, especially on the forehand. However, he had a number of double faults and unforced errors. De Minaur was the more consistent player: he never looked to be in trouble and played a more mature and measured game.
After losing the first set, Shapovalov started the second set much more positively and seemed to overcome his nervousness, winning the first four games.
Although De Minaur was composed he couldn't keep up with the aggressive Canadian. De Minaur said: "I won the first set but I still didn't think I played well. He gave away a couple of cheap games and I did the bare minimum to get over the line in that first set. Then he lifted up his game and I didn't. He found his rhythm and was hitting big balls, and I was just trying to find the middle of the racket.
Shapovalov won the second set 6-1 and said: "In the second set I found my confidence. I remember it was deuce and I had a backhand pass and I just ripped it as hard as I could. I told myself I'm gonna go for it, I don't care if I miss, I'm gonna go for my shots."
After three championship points, De Minaur hit a double fault and Shapovalov fell to the ground as the new champion.
Despite the defeat, De Minaur was still able to take positives from the match: "It was a new experience for me, and I enjoyed it. The support was unbelievable and I've got to thank everyone who came out and supported and I'm sorry I couldn't get over the line. I'm very disappointed, but obviously it's been a great week." He is now planning to take a holiday and spend a couple days on the beach in Spain.
Shapovalov also played in the boys' doubles final with fellow Canadian Felix Auger-Aliassime, but lost 6-4, 4-6, 2-6 to Kenneth Raisma and Stefanos Tsitsipas.
He paid tribute to Auger-Aliassime. "We keep pushing on each other's levels. That's one of the reasons we're doing so well at the moment."
The American pair Usue Maitane Arconada and Claire Liu were crowned champions of the girls' doubles with a 6-2, 6-3 victory over Mariam Bolkvadze and Caty McNally.
