Wimbledon 2025

What’s odd is that they have always only shown a graphic representation of where Hawkeye calculates the ball lands - no real image to accompany it.

It must be pretty accurate but can’t see it being 100%.

Makes you wonder how many wrong calls it mught have made over the years when there’s been a player challenging a human line call.

Sabalenka/Mertens - that was fantastic.

That’s because you don’t actually know how it works!

Does anyone?

(beyond a basic understanding)

This article from the current edition of Ingenia, the journal of the Royal Academy of Engineering, explains it.

Watching Alcaraz again last night, it is just about the ultimate in sporting enjoyment. Sinner vs Dimitrov later today could also be a great watch.

Great shame for Grigor this evening, he was flying.

Yes it was a shame. Sinner kept making mistakes and he was going to lose that match. As I was watching it, I did hope Dimitrov would lose, as for me, he was a boring player lacking the finesse I want to see knocking out the No.1 seed. Saying that, it didn’t give me any pleasure watching him retire. And I think Sinner was genuinely disappointed to go through like that. Sinner seems like a nice decent guy.

Oh I love Dimitrov, the single handed backhand.

He did have a damn good backhand.

Will nobody mention Norrie?
Not popular, but I’m sorry,
You might say it’s just folly,
To try and keep it jolly,
But blimey chaps and golly -
Let’s pour a glass of Bolly

Or at the very least, suck on a lolly.

Actually yes I Like Cam, he’s always been under the radar even when he was 8 in the world.

Plus, I noted that he got rid of that appalling mullet experiment.

It’s good to see Cam back in form. Plus we’ve got Jack as well . So 2 good players. Would be nice to see Kyle back in form as well.

Plus we have 4 good women with Emma,Katy,Harriet and Sonny all playing well.

The ball was clearly out. The umpire should have simply called the ball out and that was that. The line-calling system was not in activated mode on that particular part of the court for at least 10 mins. It was a human error that it was not activated and a human error by the useless umpire.

The system works and out of the thousands of line-calls throughout the 2 weeks, it is far more accurate than humans.

Like self-driving cars, they’ll make less mistakes than humans, but humans like to blame someone when a mistake is made. Humans don’t like to accept AI technology, because they like to think they’re better.

Shame the umpire wasn’t a vampire.
They could have played the match after sunset and saved a ton of electricity.

That Sabalenka Siegmund match was very frustrating to watch. Siegmund did everything unsportingly possible to throw Sabalenka. Getting up late and slow on every changeover, failing serve throw on crucial points, tapping heels with racket only on Sabalenka second serve, delaying serve and getting warnings, stupid rituals on the base line, going off late and coming back late for 3rd set….. horrible person. There’s people like that at the club and we all know exactly what they’re like, so far that it becomes a joke. She should have had more warnings. The problem was that Sabalenka fell for it and could have gone out. She needs to work on her mental strength. Such a fantastic player, but mentally weak.

Although today was the first time Sabalenka was taken to 3 sets I’m not convinced of her prowess on grass, at least in the way that she dominates on hard courts. She should be okay against Anismova, but a resurgent, although equally unproven on the turf, Swartek or Andreeva in the final could be really interesting.

Looking forward to Alcaraz, who was obviously a class ahead of Norrie, vs Fritz.

The surface wasn’t an issue for Sabalenka, it was her own errors and her own frustrations. She stood there huffing, rolling eyes waiting for Siegmund to get up, etc. She needs to grow up. Tracy Austin was very insightful and knowledgeable during that match. She should have a word with Sabalenka.
