Sinner 7-6 (7-2) 6-2 0-0 Shelton
Ben Shelton could do with a bit of good luck, but I don't think seagull droppings are what he had in mind. Fortunately, it just about misses him.
And there's no letting up from Jannik Sinner, who wraps up the set with a bruising ace.
The top seed is one set away from a second straight final in Melbourne.

A fist pump and a word of encouragement from Bryan Shelton towards his son as Jannik Sinner loops a lob long.
And there's a massive 129mph ace to see the 21st seed through and delay a third set for at least another while.

Where does Ben Shelton go from here?
I don't think his game plan is that far off really. He has been mixing it up, doing this and that, but I think he probably got into too many rallies at the end of the first set and the beginning of this second set.
He tried to unsettle Jannik Sinner, but he was always going to settle bit-by-bit so that's even more of a reason to mix up the play.
When was the last volley we saw from Shelton?

Sinner is one game away from wrapping up this second set.

Jannik Sinner has to dig deep to get that serve back over, but he's left himself flat-footed and unable to move to meet a forehand winner from Ben Shelton, whose serve proves too much again for the Italian on the next point.
The young American is on the board in this second set and he ends a five-game winning streak for Sinner.

That's a bad, bad miss. Ben Shelton is gifting Jannik Sinner these breaks.
If he can cut out those unforced errors, Shelton would be causing Sinner all sorts of problems but at the moment it's all looking rather simple for the world number one.

Jannik Sinner hits like Novak Djokovic but with a bit more power - is that even possible?
It is like Novak's hits with another 10 percent on it.
We will have to ask Alex de Minaur how he is feeling after playing against him.
