You are right about tennis being hard. I’m into my second year of playing and the sense of community is so important to me.

if you have to wet the ball, slow it down to 0 mph/stationary, and crawl on your knees to see if the ball is in or out. By the rules of the game that ball is totally in while playing.

Out

I hit the ball hard enough that it compresses upon contact with the ground 🤷🏼‍♂️

When ShotSpot shows a replay it does not count a ball that is overhanging the line as in. We've all seen a very close replay that might be 1 or 2 mm from the line. ShotSpot does not account for what is over hanging the line.

Ive been playing comp tennis for 25 years and all I've ever known is that if there's any gap between the ball and the line on the area of contact, it's out. Just look at any clay court match, even though they may have "Hawkeye" they still go by area of contact. I may be wrong here, but it's all I've ever known. Cheers All the best 😊

It's out. According to the ITF (Rule 12): "If a ball touches a line, it is regarded as touching the court bounded by that line." Real world confirmation: 1. In tournaments (especially on clay courts), if a call is challenged, the umpire will check the mark on the ground as to whether it's touching the line. 2. Hawkeye measures the area and location where the ball hits the ground (this graphic does not include the overhang).

OUT !

Technically, the way you've shown it, it's 100% out, but most honest players here would see that in motion and call it in. Hawkeye calculates (to a limited degree of accuracy), the compression of the ball against the court based on speed and trajectory (and perhaps spin???) and thus the likely actual physical contact with the court, to provide a technical view of the close calls. The demonstration in this video by pushing the wet tennis ball down into the ground shows it didn't touch the line, but you could have squashed the ball further down and it may very well have touched.

Due to compression the ball would touch the line. Here in Germany we have to keep playing, if the ball is not clearly out.

Ball was out. But being a sportsman it would be to close to call. In match play at my level it’s in all day long

If have to be technically, just image this is a table tennis table, and there is a physical step between in and out, and this ball will touch the inside surface just like in table tennis for an edge ball so this should be in.

The Rules don't talk about "over the line" - they talk about "contact".

But what is "touching" anyway? Is it the rubber body of the ball - or does the fluffed-out fur count? And, if the latter, does the electronic line tracking at pro tournaments take that into account for say furry balls on a damp day (if so, how?)

Not only technically, it is all out. While serving many parts of the body are above the baseline but it is only fault if the baseline is violated by touching.

It's out. But if you are playing a match, you would have to call it in because you wouldn't be able to tell

There isn't any debate. This ball, if there were magically a situation like this in a match (a ball that is not compressed at all upon landing), is out because it is fully outside of the line (in terms of the part of the ball in contact with the court which is all that matters). However as I mentioned, this is basically a magical scenario, as every ball will compress to some degree upon landing. So depending on the actual shot hit that lands there, it could be in or out, depending on how much the ball compresses and in which direction. But to be 100% clear, all that matters is where the ball is in physical contact with the ground. The projection of entire ball straight down on to the ground does not matter for determining if the ball is in or out, only physical contact. Additionally, this is simply too close to call for actual humans in real time, especially if you are playing and are not a line judge sitting right on that line. So realistically even though this ball is out, in a match (at the very least in recreational matches) you should CALL this in, because you can't actually be sure that this is where the ball landed.

It could be called out on clay where they check the strike and it didn't touch the line. On hard court, it would likely be called in.

Let’s get McEnroe in on this one 🎾

If I hit the shot - it’s in. If you hit the shot - it’s definitely out.

Thanks coach, great video! Now, please change that overgrip 😂

2:25 beautiful afternoon

When they use camera systems with ultra slow motion, they call the ball not touching the line "Out", although if you look on the top side the ball would visually reach the line. When players are looking at the skid mark of the ball, it is the same idea. I am not sure why you would debate this.

its out

if i was playing a game i would call it in.

THAT BALL IS OUT BUT IF IT WAS BOUNCING IT COULD TOUCH BY COMPRESSING...

The ball needs to touch the line to be in. But at the moment, the ball impacts the lineit will compress. So the example you showed would have been in.

I think the ball is technically out, and I can tell you the reason: it doesn't matter if part of the ball hovers over the line or not if it doesn't touch it, because this depends on the angle from which it is viewed. The same ball, if it's watched from the net will appear out, its shadow from that angle will be completely out, and it will be in if watched from the back of the court. In addition, the fuzz (nap) of the tennis ball could be irregular or bigger than usual, depending on the conditions. Does that mean that if the irregular part of the fuzz is over the line, the ball is in? Evidently not. So, there is no objective reason to call it in or out if you use its shadow from the viewing angle. The only objective factor that determines whether it's in or out is its contact surface with the ground, and that could take many shapes (disc, oval etc.). If any part of that contact surface touches the line, even if it's only one point, then it's in.

It's out.

for my opion i do think the ball will be out beacuse it has to be phsyically touching the line to be in. beacuse even if a bit of fluff is over the line it still not physicaly touching so it would bounce out. but tell me if i am wrong or tell me if i am right??

I feel it is in - as you were saying Jose - but the ball compresses when it lands so the pressure point would have a greater surface area then it would touch the line anyway

Usually the receiver, or one of the receivers in doubles, has a good view along the line. When the ball is that close, I think it is good practice to call it in. The area of contact in your demonstration is not a circle with the same diameter as the ball. I believe the ball 😅is in as it’s vertical shadow is in.

Is there a trade-off in how low you let the ball drop? If you don't let it drop as much then you are more likely to not be putting much topspin on and it's also higher, so those two factors mean there's more risk it goes long. Whereas the more you let it drop the more the risk that you hit it into the net. So isn't it a matter of which you are keener to avoid? If, say, you always tend to hit long would you want to try to practice hitting later in the drop? (Though perhaps you could solve hitting into the net by hitting up more, anyway, so maybe you could let it drop pretty low if you didn't mind the shot being loopy and not having as much pace?)

This was fantastic, will definitely give those tips a try on the courts! You mentioned that even if it can generate lots of spin, hitting too far behind causes loss of pace (and injury). How do I do the opposite and generate more pace at the sacrifice of spin? Do I need to change the racket path or pronate more through the ball? I'm finding my opponents can really tee off on my second once they see it 2 or 3 times because of how slow it is even though I can see there's tons of spin. I certainly hope you keep up with the videos, me and my shoulder thank you!

Can you hit some serves during

Slowly building an empire 🎉

Congrats on 1k subs 🥳🥳🤠

I try to brush up from 6 to 12 o clock but i hit the ball too thinly. How do i strike a balance between spin and forward momentum?

Nice video, as always. I stay side way as much as I can with my torso and for me it's more easy to get the kik serve.

Nicest color graded tennis video! so nice to watch.

Jose, thank you starting the channel. Will you be making videos on the topics aimed at the intermediate to advanced players? I observe that most videos on RUclips are either for beginners or focused on ATP-level play. I think the most neglected category is my current one - upper NRTP 3.5, where most adult recreational players get stuck for the rest of their lives.

Jose makin it rain

Thank you for making it 100 pervent clear that there is a difference between a KICK serve and TOPSPIN serve. Popular misconception on Reddit that they are the same when they are not. Coaches use the term in a lazy way, saying kick as a general statment of spin

The racket drop is one I was missing I guess. Will try tomorrow! Thanks！Can you talk about the net clearing height for the 2nd serve?

This is the best video I've seen on serving second serves! I struggle with my second serve and I believe I've found the solution in the different "racket drops" between first and second serve. There are so many teaching videos out there but no one else is explaining it so clearly!

Nice background color tone of the video! Your lecture catches important details that beginners can sleep on! Thank you

Would be nice if you hit some serves at the end to show the kick and height of the ball?

Subscribed for the calfs, good luck with your channel

Very cool 😊 And the cinematography is much better then mine 😅😅

Moratoglou (is it correct? I don't know xD) said that Roger is left-eye dominant. Even tho the way he performs his onbh is like he is right eye dominant. Apart from this little particular the video is insane, thank you for your tips I will absolutely try to fix my backhand.
