Righto, that’s us for today. To tidy up, Opelka is serving for the match against Onclin at 5-2 in the fourth, while Blinkova and Saville have just started their decider. Otherwise, though, we’ll see you for the start of day two, roundabout midnight GMT and 11am AEDT.

Zverev says that Pouille, when healthy, is well above his current ranking and has made the last eight of all four majors, something he has never managed. He wishes him well.

Otherwise, Zverev’s brother apparently claimed to have a higher top level … he indicates to the contrary … and the younger brother points out that at 23 titles to one, he fancies his chances. He hates having the player boxes right by the court, not wanting to see his dad and brother so much and noting he had no choice as to who coached him, but acknowledges that the sport moves on.

Pouille makes 0-15, so Zverev batters down aces 16 and 17 then runs around his backhand to smite a forehand winner down the line, raising two match points in the process…

Elsewhere, Opelka leads Onclin 5-1 in the fourth, while Savile is up 6-1 4-5 on Blinkova … no she isn’t! A squash-shotted forehand drops wide, handing Blinkova the break and a decider!

Pouille again goes to the well and holds well, to 15; it’s great to see him on the big stage, happy in himself. But after a little sit-down, Zverev will serve for the match at 6-4 6-4 5-4.

For all the good it does him. A big serve cramps Pouille, who can’t control his return, and soon after it’s 5-3. Zverev is now so good he expects to do whatever he needs to do, with good reason.

Back to Zverev, the swiftness of his holds are an underestimated aspect of his armoury. It grants opponents so little respite before they’re under pressure yet again, and Pouille seems to have spent almost all of this match serving. But he does find a way to deuce as the German seeks to go a game away … the netted forehand hands him a break-back point!

Oh Lucas. He swipes a forehand long, then can’t return a backhand, and Zverev leads 6-4 6-4 4-3, with a break. Two holds and he’s into round two.

Monstrous rally featuring drops, pick-ups, a lob …, and Zverev racing behind it to clobber a backhand winner down the line for 15-30. Ach, and when Pouille thrashes a forehand into the net he’s down to break points, the match almost over if either is converted. Zverev, though, nets a return, then misses a running pass, bring us to deuce. Elsewhere, Opelka now leads Onclin 4-0 in the fifth, while Saville leads Blinkova 6-4 3-4.

Eeeesh, again Zverev rushes through a service-game for 3-3, meaning Pouille must now deliver again. And a terrific lob from Zverev means that, at 15-all, he’s under a bit of pressure…

Pouille, though, isn’t fazed, a sizeable service securing his hold for 0-2 3-2 as we learn the Humbert, the number 14 seed, has beaten Gigante, a qualifier, in three. He meets Habib, the Lebanese qualifer, next.

Yup, Opelka breaks for 1-0 in the fourth then consolidates to love and Onclin is surely not long for this match. But Pouille is still thrashing away … even if, as I type, Zverev closes from 40-0 to 40-30 at 2-2 in the third.

It’s taken him a while, but Opelka is in charge of his match with Onclen now, yet another ace – his 27th of the match – securing set three, the lead 3-6 7-6 6-3. It’s a long way back for the qualifer.

Pouille holds then raises break point, his first of the match; Zverev quickly relieves him of it, then closes out to lead 6-4 6-4 1-1. Back on Court, by the way, we’re on serve in set two, Saville up 6-1 2-2.

Opelka, by the way, is anti-vax, Trump and so on; “Reilly’s problem is that he’s straight up stupid,” said no less an authority than his dad. But he can play tennis and os now serving for a 2-1 lead at 5-3 in the third.

Opelka looks like he’s taking over, a second successive break giving him 4-2 in set three and a 23rd ace raising three consolidation points. He only needs one, a further ace securing 5-2, and it’ll take something for Onclin to bounce back from here.

Five games in a row for Daria Saville, who leads Anna Blinkova 6-1, while Zverev quickly makes 40-0 … then whips an ace down the middle to take the second set. He leads 6-4 -4 and, though Pouille is keeping him honest, there’s doesn’t seem to be much he can do. I guess attacking the forehand is something, but that’s no longer the panacea it once was.

Pouille hangs in there, saving set-point when down advantage before closing out; Zverev must now serve for set two at 6-4 5-4. Problem is, he’s built to do exactly that.

Opelka is motoring now, a murderous forehand breaking Oncli back in for 1-1 2-2 in a really entertaining match. Tangentially, he’s mentioned in Tumaini’s piece about the latest 90s revival.

Humbert, seeded 14, has just taken the second set to lead Gigante 7-6 7-5; Bucsa has beaten Paquet 6-2 6-2.

On Court, Saville leads Blinkova 3-1, saving break-back point then closing out as for 4-1 I type, while Onclin has consolidated, now leading Opelka 2-1 in the third. Oh and Zverev, forced to go through deuce, holds to lead Pouille 6-4 5-3.

Up break point, Zverev nets a forehand, then up advantage he loops a forehand wide, but Pouille is having to fight his arse off for everything. A gorgeous pick-up, flipped cross, dips over the net, and a big first serve seals another brutally difficult hold. Zverev leads 6-4 4-3.

Pouille, by the way, fought hard for his hold, and is now serving again what seems like seconds later, Zverev holding to love in no time at all to lead 6-4 4-2. Oh, and Onclin is not going away, breaking Opelka at the first time of asking for 1-0 in the third.

Machac, the 26 seed, has beaten Nagal 6-3 6-1 7-5 and meets Opelka or Onclin next; that could be a very interesting match whoever wins on Kia.

Opelka has levelled his match with Onclin at a set apiece and, increasingly, it looks like his serve will be the difference. He was broken early doors, but has found his range now and looks more like the man who beat Djokovic last week.

I think it’s the socks: they really tie Zverev’s outfit together, just not in the way he’s intending. But his serve is a helluva shot, one of the best in the game, and I’ve not a clue how Pouille goes about breaking it. The lead is 6-4 3-2 and, as I type, another inside-out forehand ears him 15-all; pressure…

Opelka retrieves a mini-break with a forehand that clips the net then cracks Onclin on the back and drops in court; they’re now level at 3-3. On Court, meanwhile, Blinkova and Saville are under way, while Pouille is on the board in set two, trailing Zverev 4-6 1-2.

On Kia, Onclin leads Opelka 6-3 6-6; on Court 3, Walton leads Halys 6-4 6-4; and on 1573, Mahac is serving for the match leading Nagal 6-3 6-1 6-5.

It doesn’t feel like Zverev is one of those players who may or may not win a Slam; he could scarcely have got closer, having lost both finals he’s made in five sets. Rather, it feels like a matter of time, and it’d shock no one if this was his tournament: his serve and backhand are insanely fantastic shots, whole his forehand and volleying have improved significantly. He’s a big threat here, and quickly breaks then consolidates, giving this match a feeling of almost over. Zverev leads 6-4 2-0.

Pouille twice gets ahead in the game but Zverev twice closes then, at 30-all, punishes an ace out wide. But we wind up at deuce … so Zverev clobbers down a high-kicking ace, then opens body to wipe a devastating inside-out forehand cross-court for a clean winner. He leads Pouille 6-4.

Next on Court: Anna Blinkova v Daria Saville (WC)

A lovely pick-up volley from Pouille, off his tootsies, saves set point at 3-5 30-40 and Zverev applauds before two quick points force him to serve for 1-0. Meantime on Court, Lehecka is making short work of this breaker, up 5-1 on Tu, the match almost over.

Lehecka holds for 6-1 3-6 6-3 6-6, meaning he and Tu will now play a tiebreak. The home crowd are giving their man plenty of backing.

Oh, and Zverev’s rig is now there for all of us to see. Yeah, I know.

A booming backhand down the line backs up a short slice and Pouille has 0-30 on the Zverev serve. But it’s soon 30-all, a ridiculous serve out wide earns game-point, and an ace means it’s 5-3. The no 2 seed is a hold away from set one.

Lehecka quickly holds for 5-5, while Zverev consolidates and now leads Pouille 4-3 in the first.

It’s getting exciting on Court, where Tu has just held for 5-4 in set four; trailing 1-2, he’s a break away from a decider. Meantime, Onclin looks a really good player, leading Opelka 6-3 3-2 on serve. At 23, he’s plenty of time to develop and a win here should get him off the Challenger circuit.

Hady Habib, a Lebanese quailifier, is through to round two having beaten Yunchaokete Bu in three. That’s nice to see.

Calv Betton, our resident coach, gets in touch with thoughts on Pouille – who, for those unfamiliar, made the semis of this competition in 2019 and once beat Nadal at Flushing Meadow.

Calv notes that he’s a very good player hitting it nicely off both wings, but has struggled with serious physical and mental health issues in recent times. His lowest point, he said, was playing Challenger doubles in Ilkley, when his partner, Constant Lestienne, got into it with Aiden McHugh, an opponent. He’s finding his way back, though – even if, as I type, Zverev breaks him for 3-2.

Humbert has won his first-set breaker against the qualifier, Gigante – this is a big day for him etc etc – while on Court, we’re on serve in set three, Lehecka leading Tu 6-1 3-6 6-3 2-3.

I’ve now given Don McRae’s Rublev interview a proper read and you should too. It’s great to see him speak so candidly and I’m glad he getting the help he needs.

Onclin has sealed a very impressive set against Opelka, now up 6-3 1-0, while Pouille and Zverev are away with a hold apiece, the latter’s rig catching Tim Henman’s attention. Pic to follow as soon as I have it.

Who doesn’t hope this is Ons’ hour?

Clara Tauson has beaten Linda Noskova, the 29th seed, 5-7 6-3 6-4 and meets Tatiana Maria next; Tomas Mahac (26) leads Sumit Nagal 6-3 6-1; and Humbert is playing a first-set breaker against Gigante.

I should say, while those of us in the UK were sleeping, play on outside courts was interrupted by rain, so various matches – including Jerry Shang v Alejandro Davidovich Fokina – have been rescheduled.

Normal service resumes on Court, Lehecka seeing out set three to lead Tu 6-1 3-6 6-3; Onclin leads Opelka 4-3 with a break; and Zverev, looking frankly dreadful in red headband, top, socks and trainers with burgundy shorts, is knocking up with Pouille.

Rublev is, I’m told, a sound lad. He could, perhaps, do with a little help in not assaulting himself on court, but is a very fine player and the only one on tour with wins over Federer, Nadal, Murray, Djokovic, Sinner and Alcaraz. The problem he has is that he’s very very good but not quite able to beat anyone better than him in a Slam – and unless he improves his volley and slice, he probably never will.

Next on Laver: Lucas Pouille (WC) v Alexander Zverev (2).

Sabalenka is, of course, “super-happy” to be back in Melbourne and wastes no time in thanking the crowd as per protocol. It’s always tough against Stephens, she says, and didn’t play her best but is glad to be through.

Set up to say Melbourne feels like home, she says Melbourne feels like home, then it’s time to talk Tik Tok dances, the music is duly delivered, and Sabalenka leads the crowd in some rudimentary moves, the desire to “go viral” brazenly asserted by the interviewer.

Very quickly, Sabalenka makes 30-0. She knows she’s going to win, and the wahey abandon of her hitting is a joy to behold.

Stephens forces Sabalenka to serve for it at 6-3 5-2. I fear she is up to the task.

Sabalenka holds to 30 and Stephens must now serve to stop in the match at 3-6 1-5. She did well enough at the back end of the first, but hasn’t been able to play well enough for long enough to seriously trouble the champ.

With Kartal now finished, I’m having a look at Reilly Opelka, at 6”11, the tallest player ever to be ranked by the ATP. He’s struggled with injury but beat Djokovic in Brisbane the other day and leads Gauthier Onclin, a qualifier from Belgium, 1-0.

Sabalenka breaks Stephens again to lead 6-3 4-1 and this is almost over; Gaston has beaten Jasika and will face Lehecka or Tu next, the former having righted himself to break at the first time of asking in set three.

A backhand pass down the line and Tu takes set two off Lehecka, levelling the match at 1-6 6-3! He’s playing really nicely now, and this is a proper contest.

Talking of whom, Sabakenka has broken in set two to lead 6-3 2-1; as Michael van Gerwen likes to say, she’s doing the right things at the right times, and however she gets through, we can be pretty certain she will get through.

Kartal is giving Bouzas Maneiro a proper ruckus, but down 5-6 in the second-set breaker, now faces a second match point…

Leylah Fernandez is through, having beaten Yuliia Starodubtseva 7-5 6-4, and meets Bucsa or Paquet next; Gaston leads Jasika 2-1 4-2; and Noskova leads Tauson 1-0 on serve in their decider.

Kartal and Bouzas Maneiro are now playing a second-set breaker; Stephens holds to open set two, now trailing Sabalenka 3-6 1-0.

On Court, Tu is making a better first of the second set, forcing break points at 1-6 2-1 … and pumping his fist at the crowd when he eventually converts! He’s serving beautifully now too, so there’s every chance he consolidates.

Sabalenka serves out to 30 and, well though Stephens rebounded from going down 0-4, she’s now down 3-6. It’s a long way back from here and the sense is that the champ can do whatever she has to do in order to win.

Kartal fights through deuce for her hold, now trailing Bouzas Maniero 1-6 5-5, while Sabalenka is dialled back in, outlasting Stephens to eventually break again. She’ll now serve for set at 5-3 and it’s hard to see her faltering.

Sabalenka wins a net exchange for 15-40 and two break points, so Stephens chucks in a couple of moon-balls to buy time and is rewarded when the champ nets, quickly making deuce. Meantime Kartal, down match point, forces Bouzas Maneiro to hit an extra ball, it goes out, and she too makes deuce.

Oh, Kartal has broken! Bouzas Maneiro has struggled a little with the match on her racket and has plenty of work to do if she’s to close it out, leading 6-1 5-4.

Yeah, Bouzas Maneiro has rediscovered herself, breaking Kartal and now serving for the match at 6-1 5-3. As for Sabalenka, I imagine she lost a little focus after finding the start so easy and concurrently Stephens, the first set apparently gone, was able to relax into things under no pressure.

Now then! Down 15-40, Sabalenka comes in, her approach short … and Stephens flows a forehand pass past her! We’re back on serve at 4-3 to the champ! Do we got ourselves a ball-game? We got ourselves a ball-game!

Stephens is into this now, holding for 2-4, while Kartal, whose serving style is not unlike Jo Durie’s, racket coming almost from behind head, has broken Bouzas Maneiro again and now serves at 1-6 3-4.

Next on Cain: Ugo Humbert (14) v Matteo Gigante (Q)

…and Sabalenka overhits a forehand! Stephens, now playing more aggressively, is on the board at 1-4 and, while it may be too late to save this set, if she’s settled for the second, this isn’t over.

On Court, meanwhile, Lehecka has just clinched a 6-1 set one against Tu and Kartal has taken back a break to trail Bouzas Maneiro 1-6 2-4.

Talking of Andreeeva, here she is talking to Tumaini Carayol.

I can’t wait to see how she develops but, seeded to meet Saba in round four, she might be on borrowed time. That, contest, though, would be a treat – and most likely a lot closer than our current one. Sabalenka breaks again for 4-0, but Stephens quickly earns 15-40…

Of course this is our evening sesh, meaning we’ve already had a full day’s play already. I was, as you might imagine, kipping for that, but looking through what’s gone down, a few highlights;

• Arthur Fils, seeded 20, came through in four.

• Mirra Andreeva, seeded 14 and aged 17, dealt with Bouzkova 3 and 3.

• Ruud, seeded 6, beat Munar in five.

• Nishikori, aged 54, beat Monteiro in five.

Kartal has been broken at the start of set two, now trailing Bouzas Maneiro 1-6 0-3, while Lehecka is up 4-1 on Tu. Oh, and as I type, Sabalenka rushes through her consolidation for 3-0. If ever you wonder what equilibrium looks like – and, let’s face it, we’re all of us searching – this is it.

Stephens, a Grand Slam champ – she won the US Open in 2017 – and a beautiful mover, hasn’t won a match since Wimbledon and is barely in the top 100 these days. Sabalenka will know that a fast start will make her hard to catch and she quickly earns a love-hold then a break to 30. Gliding about isn’t that useful when the ball’s coming back at the speed of light. Sabalenka 2-0 Stephens

On Court, Lehecka and Li Tu are away, tied at 1-1 in the first; on Laver, Sabalenka is ready to serve and … play.

On Court 5, Bouzas Maneiro has taken the first set off GB’s Kartal 6-1 and played very nicely in so doing.

It’s not easy to work out a way Sabalenka doesn’t win this title for a third year in a row. She’s in her absolute prime – not just as a player but as a person, so settled in her life and so confident on court that it’s moving to behold. Life comes so naturally to her these days, she can make light of the sluggish balls with her frankly unprecedented power, and no one looks good enough to stop her. We shall see!

Here come Sabalenka and Stephens…
