The Slovenian got the upperhand in the first-set tie-break.
Nadal 6-3 6-4 4-2 Chung*
Double fault from Chung. The world number 170 then hauls an awkward bouncing ball towards the Statue of Liberty and Nadal is up 15-30.
Nadal 6-3 6-4 4-2 Chung*
Thunderous serving from Rafael Nadal. The Spaniard hammers his way to 30-0, then creams a huge forehand beyond a stranded Chung Hyeon and holds after the South Korean palms the next one into the tramlines.

That will be the most satisfying winner of the match! That was spectacular.
There are really promising signs for Chung if he can stay fit and injury-free for the rest of the season.

Good hold by Chung Hyeon to stave off the double break after going 0-30 down.

Nadal 6-3 6-4 3-1 Chung*
Better! Neat volleyed winner that skips off the line from Chung Hyeon to level this service game up at 30-30. But Rafael Nadal is still screeching and leaping into every point.
Chung keeps it alive, and then draws huge cheers with a cross-court winner. Nice.

Chung's coach puts his hand over his mouth like 'eurgh, that hurts'.
Nadal 6-3 6-4 3-1 Chung*
Chung tickles a forehand into the tape and then spins away in disgust. He scuttles forward to meet a Nadal short ball, but will be even more agitated after slapping that one into the tape.
0-30.
Nadal 6-3 6-4 3-1 Chung*
The three-time champ doesn't need any gimmes, but he gets another when Chung Hyeon yanks a backhand into the tramlines.
Rafael Nadal opts to take the next point on his own terms by battering a backhand winner down the line and then polishes off the hold to back up his break.
*Nadal 6-3 6-4 2-1 Chung
Wowsa. How has Rafael Nadal scooped that forehand up and over the net with such venom? What a winner from the world number two. That's crazy good. 15-0.
Cabal & Farah 5-7 4-3 Evans & Norrie*
Britain's Dan Evans and Cameron Norrie have been broken in this second set... but they are not out of it!
The pair immediately break back and if they can hold, we'll be back on serve. They still lead by a set.
*Nadal 6-3 6-4 2-1 Chung
Chung Hyeon fires a forehand across court, but it's out and that's an early break in the third set for Rafael Nadal

Nadal 6-3 6-4 1-1 Chung*
Oh, this is frustrating for Chung Hyeon. Every other shot is sloppy, and a forehand into the tramlines gifts Rafael Nadal a second break point attempt.
Nadal 6-3 6-4 1-1 Chung*
Well saved by the South Korean, leaping into a forehand winner. Deuce it is.
Nadal 6-3 6-4 1-1 Chung*

Chung, once again, goes for too much. But his coach will be telling him to keep doing that. He has to make something happen. That kind of aggression will pay off.
Nadal 6-3 6-4 1-1 Chung*
That's better. Sending Rafael Nadal scampering out wide and then slapping down a winner on the reverse side.
Another well-worked point makes it 30-15 as the South Korean finishes with a sliced volley across court, only to pump his next effort into the tape.
Nadal 6-3 6-4 1-1 Chung*
Looking a bit fatigued, Chung Hyeon. Understandably so after coming through qualifying and then playing two five-setters to get here.
Rafael Nadal eases to the hold.
*Nadal 6-3 6-4 0-1 Chung
Rafael Nadal dishes out towels to ball boys and girls like he's a primary school teacher taking his class on their first swimming lesson.
Chung Hyeon sweeps a groundstroke into the tramlines and then challenges, incorrectly.
Nadal accelerates to 30-0.
*Zverev 6-7 (4-7) 2-3 Bedene
German sixth seed Alexander Zverev still has work to do. He's a set and a break down in the second but we're still on serve.
