It was a pretty evenly matched set, although Djokovic's increased first serve percentage is ultimately what made the difference.

Good news about the ball boy who was helped by Britain's Jodie Burrage earlier in the day.
According to the All England Club the youngster is "fine".
Burrage, who gave him water and sweets, was asked about the incident in her news conference and she said: "He just said he was feeling really faint. He couldn't actually really talk. It was quite distressing to see.
"I just reacted how I think anyone would. Yeah, he was not in a good spot. I just tried to help him out as much as possible."
Djokovic 6-3 3-6 6-3 Kwon
An ace down the T, and the third set is Novak Djokovic's!
One more and his work for the day is done.

Kwon misses a first serve...
...and he's hit off court by Djokovic on the ground strokes!
Djokovic breaks and he'll serve for the set.
Djokovic 6-3 3-6 4-3 Kwon*
Is this the moment for Novak Djokovic?
He produces a wonderful return to go 15-30 up and then redirects a rally to draw the error out Kwon and work his way to two break points.
Djokovic 6-3 3-6 4-3 Kwon*
Djokovic goes somersaulting to his left as he attempts to reach a passing shot from Kwon and lands heavily on his side. Ouch.
He brushes himself off and, thankfully, seems to be OK, before getting on the board courtesy of a Kwon double fault.

Is Novak Djokovic going to carry on playing this averagely and with this lack of intensity that we don't expect to see from him? Can Kwon Soon-woo keep this level? If either of those things change then Djokovic will come out on top.
Djokovic 6-3 3-6 4-3 Kwon*
A lovely ace out wide from Djokovic helps him to 30-0, although it has landed in by the tiniest of margins.
He doesn't look overly thrilled with things but some nice foot movement ensures that he tidies up a hold and keeps the lead in this third set.
Struff 6-4 Alcaraz
Jan-Lennard Struff executes a delightful serve and volley to bring up set point and an ace seals the deal.
Fifth seed Carlos Alcaraz is a set down.
The overnight campers and early risers were back in their thousands as the Wimbledon queue returned in full force over the weekend and into Monday morning.
Those at the front of the day one queue began arriving early on Saturday evening - about 40 hours before the gates to the grounds opened - with the line officially beginning at 14:00 BST on Sunday afternoon.
Behind them, people from around the world, from first-timers to seasoned queuing pros, collected their queue card which confirms their position and pitched up their tents.
"It's a strange comeback - but the good vibes are still the same," says Danilo, from Italy, who queued for Wimbledon for the first time in 2019.
*Djokovic 6-3 3-6 3-3 Kwon
The pressure is right back on Novak Djokovic as a loose forehand from the defending champion hands Kwon Soon-woo a hold to 15.
Struff 5-4 Alcaraz
Fifth seed Carlos Alcaraz is fighting to stay in the first set on Court One.
Germany's Jan-Lennard Struff is serving for a one-set lead and is currently 30-15 up.
Djokovic 6-3 3-6 3-2 Kwon*
British summertime. There's no beating it.

What do we know about Kwon Soon-woo?
The 24-year-old reached a career-high ranking of 52 after winning his maiden ATP title win in September at Nur-Sultan.
His best run at a Grand Slam was a third round appearance at the French Open last year, and he recorded his best result at Wimbledon in 2021 by reaching the second round.
Kwon has never managed to beat a top-10 opponent in seven previous attempts, and he managed to win just four games in his only previous meeting with Djokovic. Undoubtedly, this is going a heck of a lot better so far...
Djokovic 6-3 3-6 3-2 Kwon*
There's a wry grin on Djokovic's face as he drops the ball right onto the baseline to get the advantage and he finds a nice change of direction to come through a tough service game.
