Brazilian teenager Joao Fonseca has won the second set to move a step closer to a huge victory on Margaret Court Arena, holding serve to love to see it out with no issues whatsoever.
It's a long, long way back now for Rublev, who has not lost in the first round at Melbourne Park since 2019.
The Russian ninth seed is under real threat of becoming the first major casualty in the men's draw, with talented 18-year-old qualifier Fonseca eyeing a remarkable result on his Slam debut.

That's exactly what I was asking for from Katie Boulter.
She has to fight right now, just like we saw her fiance doing on the Rod Laver Arena, so she needs to use the crowd and the shift in energy to turn important moments in the match around.
Results come down to fighting spirit at times.

Katie Boulter just can't catch a break at the moment as Rebecca Marino fires a cross-court forehand that just about pinches the line. Back to deuce.
*Boulter 6-4 3-6 0-0 Marino
A massive roar from Katie Boulter as she clings on, fighting against the pure power behind Rebecca Marino's forehand until the Canadian finally overcooks it.
But the Briton throws her hand up in frustration as she pushes a simple return into the net. Deuce.
*Boulter 6-4 3-6 0-0 Marino
The British number one needs a good start here, and she gets it. Katie Boulter looks refreshed as she returns to court and she wins the first point of the third set with a brilliant forehand winner.
But it's all downhill from there. First, it's a double fault and then she finds the net. 15-30.

Right now, we have got one player that is hitting with freedom and we have got one player that is doubting herself.
Katie Boulter is not playing with the usual freedom that we are used to seeing her play with.
*Boulter 6-4 3-6 0-0 Marino
Katie Boulter is going to need every bit of support she can get. It might be all square, but the momentum is most definitely with Rebecca Marino.
Maybe the sight of her fiancé Alex de Minaur will be the boost she needs!
Van de Zandschulp 1-6 5-7 4-6 De Minaur
First-round winner Alex de Minaur has been speaking courtside about his engagement to Katie Boulter.
The world number eight said: "Thank you everyone - 2024 was a special year and it ended in the best possible way.
"I'm very happy that it happened but, saying that, she is playing right now so I better get out there and watch her!"
*Boulter 6-4 3-6 0-0 Marino
No messing about. Rebecca Marino wins the set at the first time of asking, blazing a forehand winner past her higher-ranked opponent.
We go to a decider.

The crowd are trying to get behind Katie Boulter, and there's a roar of support as the ball bounces off the net cord for the Briton to smash down a volley.
Her luck ends there as Rebecca Marino earns herself two set points.
Boulter 6-4 3-5 Marino*
Phew. A big second serve helps Katie Boulter secure the hold and pile the pressure back on Rebecca Marino, who now has the chance to serve out the second set and force a decider.
*Boulter 6-4 2-5 Marino
Rebecca Marino takes control from the off, forcing Katie Boulter to slice her way through the point before landing the crucial blow.
The 22nd seed Briton claws her way back on the next two points, but she can't pull clear of the Canadian. 30-30.
Van de Zandschulp 1-6 5-7 4-6 De Minaur
Alex de Minaur has beaten Botic van de Zandschulp in straight sets.
De Minaur never really needed to come out of second gear, as he covered the whole court with ease, and his Dutch opponent just made too many unforced errors on the night.
It is the Australian's sixth consecutive first-round win at Melbourne Park.

Katie Boulter won both of her previous meetings with Rebecca Marino in straight sets, but it looks like things won't be quite as simple here.
After some quickfire net play, Boulter goes for the lob but Marino reacts quickly before following up the return with a passing shot at the net.
The Briton gets the better of the next point, but after dominating play from the baseline she goes long as Marino moves one step closer to wrapping up the second set.

Alex de Minaur has finally broken Botic van de Zandschulp's serve in the third set, and will serve for the match on Rod Laver Arena.
The Dutchman hit two double faults to practically hand the Australian a 5-4 advantage and put him within touching distance of the second round.
The home favourite is within touching distance now...
Boulter 6-4 2-4 Marino*
A net cord favours Rebecca Marino and Katie Boulter's momentum falters, but only briefly as she gets the hold over the line.
She's not looking happy, though, as she shouts angrily towards her coaching team.
*Boulter 6-4 1-4 Marino
Brilliant from Katie Boulter, who sends Rebecca Marino one way, then the other, before dispatching a forehand winner into the empty court left behind.
And she's not stopping there. The British number one finds each corner of the court with pinpoint precision to open up a 40-0 lead.
