This is a massive night for Botic van de Zandschulp, huge crowds and under the roof at the Australian Open. He's going to be bang up for this.
Novak Djokovic will be really pleased that there is a roof over his head and he's playing indoors in these conditions.
A hold of serve for the Dutchman levels things up at the start of the first set.

Van de Zandschulp 0-0 Djokovic*
Confirmation that the roof will be closed for the start of this match on Rod Laver Arena.
Novak Djokovic, a 10-time champion at the Australian Open and currently sitting on 399 match wins at Grand Slams, won the toss and will serve first.
Swiatek 1-0 Kalinskaya*
A brisk start from Iga Swiatek, holding to love and nailing three of her four first serves.
*Swiatek 0-0 Kalinskaya
Iga Swiatek and Anna Kalinskaya are about to get their third-round tie under way under the roof on Margaret Court Arena.
World number two Swiatek will serve first against the 31st seed. She was broken early in both sets in her previous match, remember...
Van de Zandschulp v Djokovic
Image source, Getty ImagesNot many players head into a meeting with Novak Djokovic knowing they've won their most recent match against the Serb, but that's the case for Botic van de Zandschulp.
The 30-year-old defeated the 24-time Grand Slam champion in three sets in Indian Wells last year.
Their head-to-head record reads one win apiece, with Djokovic victorious in Astana in 2022.
Van de Zandschulp has also already caused a couple of upsets in Melbourne, downing 27th seed Brandon Nakashima in four sets in the men's singles first round and combining with Dutch partner Tallon Griekspoor to eliminate the 11th seeds at the same stage in the men's doubles.
Swiatek v Kalinskaya
Image source, ReutersSecond seed Iga Swiatek - first up on Margaret Court Arena - has made a mixed start to her quest to complete the career Grand Slam.
She produced an error-strewn outing against Yuan Yue in round one and admitted she had "stuff to work on" following a performance with "many ups and downs".
She was much happier following her 6-2 6-3 win over Marie Bouzkova, experiencing "more freedom" in her game, but concerns about her serve persist, with the 24-year-old Pole broken early in both sets.
However, she's through to the third round without dropping a set and having reached at least the quarter-finals in her past five major outings, she'll be confident of extending her stay in Melbourne.
Challenging Swiatek for a spot in round four is 31st seed Anna Kalinskaya, who has also come through her opening two matches in straight sets.
The 27-year-old reached the Australian Open quarter-finals in 2024 - one of only two appearances beyond the fourth round in her Grand Slam singles career - but lost both of her meetings with Swiatek last season.
Van de Zandschulp v Djokovic
Image source, Getty ImagesKicking off the evening session on Rod Laver Arena is fourth seed Novak Djokovic, who faces Dutch world number 75 Botic van de Zandschulp for a spot in round four.
Djokovic is no stranger to reaching the second week in Melbourne - he's a 10-time champion after all and his most recent exit from the tournament before the fourth round came in 2017.
Van de Zandschulp has only reached the fourth round at a Grand Slam once (Wimbledon 2022) and has matched his previous best showing at the Australian Open (2022) by reaching round three.
Fritz 7-6 (7-5) 2-6 0-0 Wawrinka*
Image source, ReutersStan Wawrinka has taken the second set, breaking Taylor Fritz in the second and eighth games and also saving two break points on his own serve.
Game on!
We'll be keeping you across that game but now it's time to switch our attention to the show courts where Novak Djokovic and Iga Swiatek are coming up against Botic van de Zandschulp and Anna Kalinskaya, respectively.
*Fritz 7-6 (7-5) 2-5 Wawrinka
Stan Wawrinka saves two break points to preserve his lead.
Taylor Fritz will serve to stay in the second set.

Former British number one on BBC Radio 5 Sports Extra
Stan Wawrinka seems to be playing with so much freedom on the court.
He's announced that this is going to be his last season on the tour and that backhand is absolutely firing as well as it ever has.
We should enjoy it while he's still thumping it for winners down the line because it's quite a sight to behold.
The crowd noise is lifting him, he's given them what they're cheering for and he's inspired.

Play is further delayed on the outside courts, with the earliest possible restart pushed back to 08:15 GMT.

*Fritz 7-6 (7-5) 0-3 Wawrinka
Well, well. Stan Wawrinka has made an early breakthrough in the second set against ninth seed Taylor Fritz.
The 40-year-old failed to convert either of his two break points in the opening set but struck at the first opportunity in the second, breaking Fritz in his opening service game.
Wawrinka has consolidated the break with a hold to 15 and leads 3-0.
Image source, Getty ImagesWorld number one Carlos Alcaraz dropped just seven games in a routine win over Corentin Moutet on Friday while women's top seed Aryna Sabalenka also came through in straight sets against Anastasia Potapova, although she was taken to two tie-breaks.
Home favourite Alex de Minaur, the sixth seed, came through in straight sets against Frances Tiafoe, 25th seed Learner Tien downed Nuno Borges and fellow American Tommy Paul was 6-1 6-1 up when his opponent Alejandro Davidovich retired.
However, 13th seed Andrey Rublev - a former quarter-finalist in Melbourne - fell in straight sets to Argentina's 18th seed Francisco Cerundolo while Cameron Norrie lost to third seed Alexander Zverev in four to end British hopes in the singles.
Daniil Medvedev had to come from two sets down to defeat Hungary's Fabian Marozsan.
Canadian rising star Victoria Mboko and third seed Coco Gauff also went the distance. Seventeenth seed Mkobo beat 14th seed Clara Tauson 7-6 (7-5) 5-7 6-3 while Gauff roared back from losing the opening set to defeat Hailey Baptiste.
American teenager Iva Jovic stunned seventh seed Jasmine Paolini, winning in straight sets.
And there was an upset in the men's doubles, with British top seeds Julian Cash and Lloyd Glasspool falling in two sets to James McCabe and Li Tu.
Image source, Getty ImagesOne thing you don't want to do on a day like this is to be out on court too long.
Some of the top female players managed to get their matches done quickly - Amanda Anisimova, Jessica Pegula and defending champion Madison Keys all got their third-round ties won in straight sets.
Fellow American and men's eighth seed Ben Shelton also progressed in straight sets, beating Valentin Vacherot 6-4 6-4 7-6 (7-5).
However, fifth seed Lorenzo Musetti wasn't so lucky. He beat Tomas Machac in a five-setter that lasted almost four and a half hours, with only the final portion of the contest being played under the roof on John Cain Arena.
Fritz 7-6 (7-5) 0-0 Wawrinka*
Stan Wawrinka had to come from a set behind to beat Laslo Djere in round one and came through a five-setter against Arthur Gea in round two. And he'll have to take the scenic route once again against Taylor Fritz if he wants to prolong his Melbourne farewell.
After the first set went with serve, American ninth seed Fritz won the tie-break 7-5.
Spizzirri 6-4 3-6 4-6 4-6 Sinner
Image source, Getty ImagesDefending men's champion Jannik Sinner, speaking on court after his four-set win over Eliot Spizzirri:
"Eliot is an incredible player, he played really well today and I wish him only the best. I'm sure he will have a great season this year.
"I struggled physically a bit today and I got lucky with the heat rule. They closed the roof, I took my time and as the time passed I felt better and better.
"I'm very happy about this performance. Looking back, in every big tournament I've had, there were some really tough matches. Hopefully this can give me some positives for the next round, starting with a good mentality again and then we'll see what's coming."
On his physical condition during the third set, just before the heat rule was enforced:
"I started with the leg, then it got into the arm and I was cramping a bit all over. This is the sport, I know this is an area I need to improve. It's a positive thing I will try to work on every day and I have a great team behind me, who are pushing me in the right direction.
"At the same time, tennis is a very mental game and I tried to stay as calm as possible. I'm here to fight, play every point in the best possible way and today we saw the outcome - even not playing at my best, I tried to do my best. The crowd gave me a lot of support and it means a lot to me.
"I know if I want to go far in this tournament, I need to play in hot conditions. It's not only for here, it's for the rest of the season. But I'm looking forward to it. It's great for me that I have at least one more match to play here and we'll try to do our best.
"Now it's most important [to get some] recovery and prepare for the next match."
Spizzirri 6-4 3-6 4-6 4-6 Sinner
Image source, Getty ImagesDefending men's champion Jannik Sinner was really struggling in the intense Melbourne heat earlier.
The Italian lost the first set and although he took the second to level the match, it was clear he was in difficulty physically - visibly cramping and being hardly able to move in the early stages of the third set.
With Sinner 3-1 down, the Australian Open's heat stress scale hit five - meaning play was stopped and the roof on Rod Laver Arena was closed.
After play resumed, Sinner won five of the next six games to win the third set 6-4 and recovered from a break down in the fourth set to win that by the same score.
Sinner, who will play fellow Italian Luciano Darderi in round four, conceded afterwards that the enforced stoppage worked in his favour.
