Sinner ends 10-time champion Djokovic's unbeaten streak in Australian Open semifinals

Sensational Sinner! This kid is amazing. His returns to break Djokevic were outstanding.

Hopefully Sinner lifts the trophy on Sunday to usher in a brand new era!

I've never seen Djoko in such poor form, not at a slam. And Sinner played brilliantly, as he does recently. With only 1 set dropped the entire AO, he has a great chance in the final.

Looking forward to a great battle next, Medvedev-Zverev

Well done Sinner but indeed Djoker got out of the gates slow. Probably the day session didn't help him read the tough Sinner serve and amazing 1st serve %.

Give Zverev the slight edge but Medvedev in form. Sinner will be the favorite Sunday regardless.

Congrats to Sinner! Djoko is not as good when having to play day matches and he didn't play well here, which reminded me of his day semi-final against Nishikori at the US open many years ago.

Congratulations to Sinner. And congratulations to Novak Goatovic for staying number one player in the world at 36 years of age! Amazing!

Djokovic should now be looking at a future behind the mic, his glory days are behind now, as the next generation jostle for position at the top.

Djokovic should now be looking at a future behind the mic, 

Not sure all ex-players should be "behind the mic". Jim Courier is outstanding, as is the "Superbrat" McEnroe. Kyrgios not so great. I guess Novak could be decent on Serbian TV, however.

Peter, you are talking about the No. 1 player in the world, who had a bad day and lost a semifinal at a grand slam. If that's a reason for retiring, then there would be no players left on the pro circuit.

Awesome job Sinner, I think he has only lost one set this whole tournament. Medvedev vs Sinner is going to be a great Final. The cherry on top is no Joker, absolutely can't stand that guy, fantastic player but apart from that can't stand him. I miss Federer.

Well played Jannik Sinner.
