David Law
Commentator on BBC Radio 5 Live and BBC SoundsTaylor Fritz was rocked in the first set. It's all well and good to have a plan but then you have got to feel the shots of your opponents and I don't think he liked what he felt.
This is the best I have seen Jannik Sinner look in the tournament.

Sinner the favourite on paper, but not sure you can put a value on the cauldron like atmosphere the American fans will create for Fritz. I'm sure whatever happens tennis will be the winner!

*Sinner 4-3 Fritz
Annabel Croft
Former British number one on BBC Radio 5 Live and BBC Sounds
Image source, Getty ImagesThat was quite brilliant from Jannik Sinner.
He has just stepped it up a gear. He is finding out what Taylor Fritz has to offer and I feel like he is very comfortable with the pace of the match, how he is striking the ball from the back of the court, how he is defending and turning those defensive positions into attack.
Fritz keeps turning around to his camp. Tactically what can he do? He's not going to beat him from the back of the court.

Head says Sinner in 4 and Heart says Fritz in 5. I think if Sinner hits his full level, then he wins. But if Fritz executes his gameplan and Sinner's level dips, then it could be an epic. I think I need a fence to sit on and watch this. Good luck both.

Jannik Sinner isn't getting this all his own as the opening two games suggested might be the case, but he gets the hold.
