00:30 CET - That's all from us today in our live Tennis Tracker, but we'll be back tomorrow as the BJK Cup and Laver Cup both come to dramatic conclusions!
00:16 CET - Team Europe are officially in the lead! Casper Ruud and Alexander Zverev have beaten Alexander Bublik and Brandon Nakashima 6-4, 7-6(7) in the day's closing doubles clash to put their team narrowly ahead in the overall score.
Finley Crebolder at the O2 Arena: What a day that was. All three singles matches went to deciders, two saw the winner save match points, and all four made clear just how evenly matched the two teams are this year.
The final outcome, two wins apiece, leaves Team Europe 7-5 up heading into the final day. That means that, with 13 points needed for victory and three points being granted for a win, we're guaranteed two matches at the very least on Sunday.
You'd expect both captains to pick their best players, meaning we should get some top-level matches and undoubtedly more high-stakes drama.
23:21 CET - Casper Ruud and Alexander Zverev have taken the first set against Alexander Bublik and Brandon Nakashima 6-4 to put Team Europe in front in the day's closing doubles tie, and narrowly ahead with the overall scores tied at 5-5.

22:30 CET - We've got just one match to go at the O2 this evening, and it's the doubles tie, with Casper Ruud and Alexander Zverev teaming up for Team Europe against Alexander Bublik and Brandon Nakashima of Team World. Whoever wins takes the lead!
22:14 CET - What an ending to this match at the O2. Carlos Alcaraz has edged Taylor Fritz 13-11 in the super tiebreak to clinch their singles tie and level the scores between Europe and World at 5-5.
Finley Crebolder at the O2 Arena: Cometh the hour, cometh the Carlos!
Fritz barely put a foot wrong from the start of the second set to take things to a decider and stay with Alcaraz all the way to the end of it, but in a way only the true greats can, the Spaniard upped his game when it mattered most.
In an incredibly dramatic conclusion, he hit a drop shot when match point down before returning a smash from Fritz, and then produced another drop shot when match point up. Absolutely box office.
It wasn't vintage Alcaraz all the way through, but he showed glimpses of his mind-blowing best and picked the right moments to do so, and that was enough.
As a result, Team Europe head into the last match of the day level at 5-5 instead of 7-3 down. It's fair to say we may just have seen some tournament-defining strokes of magic.

21:52 CET - Taylor Fritz has battled back to win the second set against Carlos Alcaraz and force a super tiebreak in this last singles rubber of the day. The match stands at 6-3, 4-6.

21:15 CET - Carlos Alcaraz has taken the first against Taylor Fritz, 6-3.
Finley Crebolder at the O2 Arena: Carlos Alcaraz is a bit good at tennis... Who would've thought?
Team Europe desperately needed him to be on his game tonight, and he has been so far. 23 winners in one set of tennis is pretty good going.
Fritz is in this, though. He's had some openings on his opponent's serve, and De Minaur turned things around earlier after losing a much more one-sided opening set.
That being said, his opponent wasn't Carlos Alcaraz.

20:20 CET - We are just minutes away from the final singles clash of the day at the O2 Arena, with Carlos Alcaraz taking on American Taylor Fritz. Team World are currently leading the tie 5-3, so an Alcaraz win would level things for Europe.

18:35 CET - Finley Crebolder at the O2 Arena: Wow. What a win that was from De Minaur. He took every chance he got and gave absolutely everything, quite literally leaving his blood on the court, to turn that around.
On the flip side, Zverev just didn't keep his nerve in the big moments, failing to convert when serving for the match at the end of the second set and then failing to put away a match point in the deciding tiebreak.
That leaves Team World 5-3 up and Team Europe desperately needing Carlos Alcaraz to beat Taylor Fritz. The Demon has delivered.
18:21 CET - De Minaur downs Zverev! A gruelling battle has ended 2-6, 7-6, 11-9 to the Aussie after just over two hours.
After fighting back from a set down, he then saved a match point in the deciding tiebreak to claim a win that felt near-impossible just an hour before.
18:07 CET - Finley Crebolder at the O2 Arena: Zverev looked set to seal a comfortable win when he bounced back from an early break and took control of that second set, but with the crowd behind him - there are a fair few Aussies in the arena, and the fact he's married to British player Katie Boulter may help - De Minaur forced three break points when Zverev was serving for the set and took the second thanks to a double fault.
He then carried that momentum into the tiebreak, where he played some of his best tennis of the day.
18:04 CET - We have yet another decider on our hands, with De Minaur fighting back from a break down to steal a topsy-turvy second set!
17:04 CET - Finley Crebolder at the O2 Arena: It was always difficult to see this match-up unfolding any other way. De Minaur's only real weapon is his speed, and with how well he's hitting the ball and how aggressively he's playing these days, Zverev has the power to make that speed fairly obsolete.
The Aussie did beat the German at this event last year, but I don't think he's as good a player as he was back then after a difficult season, and his opponent - winning two Grand Slams between then and now - has taken his own game to another level.
Pretty much everyone in the stadium would be surprised if this went to a decider.
17:00 CET - As many would have expected given the respective 2026 seasons that they've had and the German's form of late in particular, Zverev has stormed through the first set against De Minaur, winning it 6-2 in just 38 minutes.
16:03 CET - Finley Crebolder at the O2 Arena: That was a great win from Tien on his Laver Cup debut. The momentum and the largely European crowd were very much against him when Cobolli fought back from 8-4 down to 8-7 in the deciding tiebreak, but the young American kept his cool really well.
Match point may have been his best of the match, with him staying alive in a long rally before sealing the win with a great passing forehand.
That being said, it wasn't a great performance from either, with mistakes aplenty on both sides of the net; the team captains won't feel too confident about picking them for one of tomorrow's matches.
The stage now couldn't be set any better for the most high-profile match of the tournament yet: Alexander Zverev vs Alex De Minaur.

15:58 CET - Team World draw level at the Laver Cup! It's now 3-3 thanks to Learner Tien, who has beaten Flavio Cobolli 6-3, 6-2, 10-7.
What a way to win it too, with the American edging a gruelling rally to seal the all-important two points for his team.
15:41 CET - To a 10-point deciding tiebreak we go at the O2! Cobolli upped his game massively in the second set, putting pressure on Tien's serve from the off and going on to get two breaks and prevail 6-2.
Now, the tiebreak will determine whether Team Europe extend their lead to 5-1 or Team World level things up at 3-3. This is big.
15:06 CET - It's advantage Team World in London, with Tien winning the first set of the day 6-3.
Finley Crebolder at the O2 Arena: That was a seriously scrappy set from Cobolli, who hit four double faults, 21 unforced errors and just three winners. The Italian has seemed particularly uncomfortable on his forehand side.
While not at his best himself, Tien has been much more solid, and deserves his lead.
14:26 CET - Finley Crebolder at the O2 Arena: Tien has made the perfect start here, breaking serve in the opening game, helped by a double fault from a nervy Cobolli.
The pressure is all on Tien here; a loss for the American would leave Team World 5-1 down and with a big mountain to climb, especially when you consider that they'll have to deal with Carlos Alcaraz in singles action later today.
14:12 CET - Ukraine are through to the BJK Cup decider! Elina Svitolina has dismissed Italy’s Jasmine Paolini 6-2, 6-2 in just over an hour to seal a 2-0 win in the semi-final for the Ukrainians, following Anhelina Kalinina's victory earlier.
Svitolina’s dominant display snaps Paolini's incredible 10-match winning streak in the competition, and sends her country through to their first-ever BJK Cup final. Ukraine will take on the Czech Republic in a blockbuster finale tomorrow.

13:40 CET - We're just 20 minutes or so away from today's Laver Cup action getting underway, as Team Europe look to build on their 3-1 overnight lead when Flavio Cobolli takes to the court against Team World's Learner Tien.
ScoresStat's Finley Crebolder is in attendance at the O2 Arena in London, so we'll have plenty of insights throughout the day!
13:03 CET - Over in Seoul, fifth seed Maya Joint has sealed her place in the final of the WTA 250 event after her opponent Alina Korneeva was forced to retire while trailing 2-6, 0-1.
Joint will face fellow Australian Kimberly Birrell in tomorrow's showpiece in South Korea.
12:42 CET - Ukraine have taken a 1-0 lead in their BJK Cup semi-final tie against two-time defending champions Italy, with Anhelina Kalinina proving too strong for debutant Tyra Caterina Grant in a 6-3, 6-4 triumph.
Kalinina was impressive throughout, winning 76% of points behind her first serve, while she didn't face a single break point across the two sets.
Ukraine are now just one victory away from reaching their first-ever BJK Cup final, as Elina Svitolina prepares to face Jasmine Paolini in the second singles rubber.

11:13 CET - Today's BJK Cup semi-final is now underway in Shenzhen, with Italy's Tyra Caterina Grant taking on Ukraine's Anhelina Kalinina in the opening singles rubber.
