It all comes down to fluff.

Before each serve, most professional tennis players go through a ritual to get in the zone. Novak Djokovic will bounce the ball with his racket, then with his hand. Rafael Nadal will usually pull his shorts and the sleeves around his shoulders, then touch his nose and tuck his hair behind his ears. All very distinct routines. But there’s one tennis ritual nearly every pro tennis player does: choosing a specific tennis ball. A common belief among players is that the ball they choose can help them win.

But there’s real physics at play behind this ritual - and It all comes down to the fuzz. For a faster serve, players try to find a compact ball. For a slower serve, they feel for more fuzz. The idea is that a fluffier ball is more likely to be slowed by drag as it travels through the air - and that choosing the right level of fuzz can help the serving player defeat their opponent.

Once a ball boy said he remembered a ball that got rejected and he gave that ball again and this time he didn't reject it ,and the both cases were similar for the second serve, so I think it's just for show

Still halfway thru watching the video but I already can't help but ask: can't we just start and consider redesigning the tennis ball -- use a different material that doesn't fluff? Isn't that possible? They did it with the basketball [ball], right?

I always thought the players keep the ball in heir pocket so it could warm up and become a bit bouncier. If you see any pro player serve a net roller and they get another first they always keep the ball in their pocket and ask for a new Ball.... I thought that is because of the heating of the Ball for the second.

I think the routine has to do with it you want to play with one shot at a time even if you've lost three points in a row it has no meaning whatsoever everything is one shot at a time and so what they do is if they lose a point they start a routine because once they finish this routine which might be slap themselves in the thigh or playing with their hair or something it's kind of like a reset the economy it it it's okay this that point is gone forever the only thing that matters is right now so the focus is the mindset that is always in right now play one point at a time that's the secret to tennis is one shot at a time one point at time you don't want to think forward or you don't want to look back you're always want to be in the here and now that's a mindset mindset is 100% of the tennis game they already know by the handshake whether he's going to win the match or not it's all they already know whether they're going to win or lose because of their mindset going out there if you're confident you have a like a 90% chance of winning but if you walk out there knowing that you're going to lose because you've been beaten so many times before by the same opponent it's almost like you just give up by the time you do the handshake it's a done deal

Right because they want to cut the water you trying to make a cut when you're doing judo to throw the guy everything's a cut like you're cutting the tennis ball trying to get a sharper angle or the cut is what puts his spin on the ball and this is a precise cut at the top level whoever can cut it cleaner or more precise has either a better top spin than the other player or a better slice so the better you get the better you are able to cut the cheese at this point it's your serve and everything that boils down to the cut making the cut has to do with how you cut the ball and that's fluff has a lot to do with the drag
Douglas Hagan
Douglas Hagan Månad sedan
Right that second ball you want to put a lot of spin on it cuz you want to control it but usually at the top level they're willing to take a huge risk on their first serve to get an ace so they really don't care if the first serve goes in because they know they've got a really good spin second serve that goes in 100% of the time

Oh wow, Medvedev is featured here 😲. I guess it's because he serves great. I've seen him in a video where after a game on his serve, he asked to be tossed that same ball again for his next serve.

Did a bit of research.. apparently the speed of the oldest and fluffiest ball used versus a new one accounts for 1 to 1.5km/h A difference which is roughly the speed of a baby crawling on the floor

Someone call me out if I’m being delusional, but is this the same “routine” as the one in kaguya-sama love is war? If you can’t remember, she would rest her hand on her cheek when she needed to focus around shirogane.

They need to do an experiment on what’s the impact of the second ball in the players pocket when they serve. i believe it impacts more than this proved experiment.
