Some more frustrated cries of “Taylor” from the crowd as he sees three break points come and go in the first game of the third set.
Having not seen a break point in the whole of the second set, he’ll be as annoyed as anyone not to have been able to capitalise on that opportunity.

This would be the monumental comeback of all comebacks if Fritz pulls this off. For all the plaudits for Fritz saying he played well second set, it's been too easy for Sinner. Very disappointed as wanted a decent final. Occasion seems to have got to Fritz.

This is a long, long way back for America's Taylor Fritz who throws his hands up in the air towards his team as if to say "what can I possibly do about this?"
Jannik Sinner is firing.
*Sinner 6-3 6-4 Fritz
Wow.
A big player for the big moment.
Jannik Sinner with a stunning backhand down the line.
Is there any way back from here for Taylor Fritz?

Not an ideal start from Taylor Fritz as he goes long with a forehand before finding the net.
0-30.

The biggest difference between the two players is the movement.
Even if Taylor Fritz can hurt Jannik Sinner with the groundstrokes, Sinner can defend those much better than Fritz can.
