0-40.
Three set points.
The first is saved.
Zverev 3-6 2-6 6-3 5-3 Carreno Busta*
PCB's game has fallen apart - Zverev is using him like one of those yo-yos where you performed the 'rock the cradle' trick in front of your mates.
0-30.
Zverev 3-6 2-6 6-3 5-3 Carreno Busta*
Zverev holds again to love with a tapped forehand winner after a well-placed serve wide.
He looks very confident now.

It's hardly dream tennis but Zverev is doing just enough. When he gets on the front foot he does have a bit more firepower - he needs to use it more.
*Zverev 3-6 2-6 6-3 4-3 Carreno Busta
Zverev takes the second with an emphatic forehand smash at the net. Are they anything but?

Two break points as PCB drives long.
Here we go again.
Zverev 3-6 2-6 6-3 3-3 Carreno Busta*
The Spaniard then goes for the head as Zverev comes to the net. Something he should have done on a point in the first set.
15s each.

PCB is really going for it with his first serves. Lack of energy for rallies?
He's love 15 after a backhand goes long at the end of a rally.
Zverev 3-6 2-6 6-3 3-3 Carreno Busta*
Zverev holds to 15.
It's the first to blink in this set. I realise they've both already blinked.
*Zverev 3-6 2-6 6-3 2-3 Carreno Busta
The 20th seed holds thanks to a big first serve and forehand error from Zverev which sees the ball ping off the frame.
Zverev 3-6 2-6 6-3 2-2 Carreno Busta*
Another nervy service game before PCB serves an ace - only his third of the match.
But his backhand lacks conviction and we're in for another deuce-a-dong.

This is a massive opportunity for both players and the nerves are high. It's normal and you have to feel for them.

Would these guys be playing much better tennis if there was a crowd?
For some reason the semi-final between Serena Williams and Victoria Azarenka was played with a lot more oomph.
Zverev 3-6 2-6 6-3 2-2 Carreno Busta*
Zverev's double-handed backhand from the baseline drifts out of bounds.
Woeful tbf.
*Zverev 3-6 2-6 6-3 2-1 Carreno Busta
0-40 as Zverev double faults. What?!!!

I don't think what Carreno Busta has just said is repeatable. He's disgusted with himself.
it's not easy when you have a big lead and it looks like you're heading for a fifth set. He's got to hang tough, get his intensity back up and hope Zverev has one of those shocking service games.
*Zverev 3-6 2-6 6-3 2-1 Carreno Busta
This is a certain set for Zverev to draw level. Certain.
*Zverev 3-6 2-6 6-3 2-1 Carreno Busta
A second serve and he's broken Carreno Busta once more as the Spaniard's forehand lands long.
Gutsy from Zverev.
