Topslice: it's nice.
No. It's a slice serve that you hit up on a little more. It's by far the most common and successful second serve in the history of professional tennis. It's a label of convenience. Many just call it a slice. Those of us who teach sometimes alter labels to help students understand.Is that the kick serve?
Topslice works well for Ivanisevic, McEnroe, Feli Lopez, Nadal and the rest of ATP lefties because their topslice go to a righty's BH.No. It's a slice serve that you hit up on a little more.

The kicker has probably superseded it in the modern game, at least among the men. Though you'll still see plenty of both. And both are more common than straight topspin, just because movement is your friend, and they both move a lot more than simple rollers.
Who has great kickers? Isner. (Mostly a function of his height.) Thiem. Rafter used to have a million and twelve nasty spin varieties he could throw at you. I'm sure there are millions more, but those spring right to mind.
Topslice? Ivanisevic. McEnroe. The huge majority of the WTA. The huge majority of everyone before 1990. Feli Lopez today(though he will hit a variety of spins, like Rafter). Karlovic (usually). Djokovic. Nadal.
Yeah, you're almost crazy not to use it if you're a high level lefty. But that aside, it's very effective for countless righty pros as well.Topslice works well for Ivanisevic, McEnroe, Feli Lopez, Nadal and the rest of ATP lefties because their topslice go to a righty's BH.
A good American Twist kicker is not easy to hit well but if you do as a righty, it is a game changer.
If I get a good serve into my opponent's BH esp. in doubles, there is ~80% probability we will win that point.
8-2 = "topspin slice" = bounces to left
7:30-1:30 = "topspin" = bounces straight
7-1 = "twist" = kicks to right

Spin directions
Black - top spin, ball id spinnin on a horizontal axis.
Red - slice
Blue - kick serve spin
This is my interpretion on kick.
The top spin (black spin direction) is quite straight forward and down by gravity enhanced by aerodynamic force from the spin faster than a flat ball would drop. If initial flight is high enough the landing angle gets steep and the bounce is up and forward towards the spin direction. The amount of spin does not make big difference in the bouncing direction.
On a pure slice the drop is caused mainly by gravity and direction will change due to aerodynamic lift pointing sideways. Slice does not usually have the same amount of spin as does the topspin or kick, and the bounce does not create as much force to slow the ball down, cause there is very little friction between the bottom of the spin axis, cause the spinning reduced the friction.
A kick serve has about or some more revolutions as a topspin. The trajectory is different and it drops faster and to the side more than topspin trajectory. The landing angle gets greater, while the spin axis, spin direction changes towards slice closer to bounce. Impact with the court adds a force effecting the high rev ball, which now is spinning close to slice direction and results a gyro effect on the behavior.
The harder, you are able to hit the 45° spin axis ball adding revs, the bigger gyro effect, the higher and the more to right for right hander it will bounce. I think a serious kick differs from topslice only by the amount of spin.

This picture gives about the most complete information on ball spin and serve types that I have come across. The publication also discusses the state of knowledge for spin rates and spin vector directions. The ball spins around the arrow as its axis. The length of the arrow indicates the spin rate in revolutions per second or minute. AVx, AVy and AVz indicate components of the ball's spin vector (a complete description of ball spin for that time and location). All serves were to the T in the deuce court. Only serves landing in a 1 x 1 meter target area were averaged.
Some points:
* AVx is closely associated with spiral spin or gyrospin as it is also mostly forward into the court .
* The kick, flat and slice serves all have considerable gyrospin components. See the dotted lines parallel to the x axis for each arrow. These dotted lines indicate the components in the direction of X(forward) very similar to spiral spin.
* The kick serve has a larger side spin component, AVz, than the slice serve. Doesn't sound right......but there it is.....
* The kick serve has a much larger top spin component than the slice or flat serves. That makes the ball hit the court at a sharper angle and bounce high.
* The racket stings travel approximately perpendicular to the arrows.
* The publication points out that all three type serves are in the same "octant" or 1/8 of the circle. In other words, the flat, kick and slices serves all have components of top spin, side spin and spiral spin in roughly the same direction, spin vector arrows up and to the left.
In reality the KICK serve and TOPSPIN serve are the same, not sure why some people say they are different serves, they are not, but people call them different names for some reason.
There are really 3 main serves:
1.FLAT serve
2.KICK/TOPSPIN serve
3.SLICE serve
Then there are also 2 serves that are basically KICK/TOPSPIN and SLICE but have some more pronounced properties
4.TOPSPIN SLICE serve
5.TWIST/KICK serve
Theres a little bit confussion because some people call the KICK serve TOPSPIN serve, and some people call the TWIST serve a KICK serve, so its a bit confusing at times, but to explain each serve and how they look like:
Heres the explanation based on the picture above:
1.FLAT serve is basically hit directly through the target, the racquet swing path is throughout the ball and towards the target, in reality no serve is completely FLAT, every serve has slice and topspin, its just that the FLAT serve is trying to hit with as minimum spin as possible and as direct as possible with minimum spin and most pace
2.SLICE serve is basically all that is colored blue, the ball has primarly a TON of sidespin and minimum topspin, the amount of topspin you add depends how much you want the ball to curve where, if you want more sidecurve you add more sidespin by swingpath going more on the lower part of the blue, if you want less sidespin bit more topspin spin into the court the swingpath is a bit more on the upper blue part.
3.TOPSPIN SLICE serve is basically a SLICE serve but its when you start hitting so much more up and less sideways that you get more into the red area, at that point you get quite a bit more topspin and less sidespin, but still quite a bit of sidespin
4.KICK or TOPSPIN serve is basically hitting more upwards and creating a ton of topspin to pull the ball into the court, hence why your throw is more behind, so you can brush upwards more, you can't hit a KICK serve with a normal flat or slice toss.
5.TWIST or KICK serve is basically the same as number 4. just that the swingpath is more sideways than the usual kick serve, the more sideway it is the more the ball will KICK to the side hence being called TWIST by some and KICK by others, and the more upward its swingpath is the more the ball will KICK upward into the air hence being called TOPSPIN by some or KICK by others.
IMPORTANT NOTE:
Every serve has a ton of variety, these serves are just the main names that people came up with in order to name certain effects the serves have.
But the reality is, each and every serve starting from FLAT to SLICE to KICK has many different spins on it, even a FLAT serve, its impossible to hit a FLAT serve that has completely 0 rotation in any axis, its just the amount of which spins the ball has that in the end give it a certain effect and hence they are called a SLICE serve or whatever.
But in reality the players who hit it have many different variations of each serve, they can hit a SLICE serve with a TON of sidespin, or they can hit less sidespin and more topspin to pull it into the court, same as flat serve, you can hit a pure flat serve or you can hit with a bit more topspin, there are a MILLION variations of each serve depending on what you want to do with the ball and where you want to hit it and how you want to curve it.
And all these variations are changed by the player by altering their position, their toss position, their swingpath etc..
question: can you put topspin on a flat serve without it being slice?
question: can you put topspin on a flat serve without it being slice?
You can think of all sorts of spins on the ball. But in serving there are constraints to what a server can do. Such as, the racket rises and/or moves to the right during impact. That is why the flat, kick and slice serves all have their spin axes in the 'same octant' or 1/8 of a circle. There is no such real high level serve with pure topspin or pure slice. All spin axes are about as shown in the ball/spin vector diagram. The spin axes will be about perpendicular to the direction of racket string travel during impact.
See that the spin axes are all up and to the left,all type serves in the 'same octant'.
Now a trick question - what type of serve has the spin component with the greatest sidespin?
Yes, but it wouldn’t be a flat, if you did that.
Spin exists in 3 dimensions. To specify spin in 3D, a vector component is given for each of three directions. Search Vectors. The diagram of the ball shows the 3 components that together specify the ball spin vector. These are also often called 'slice', 'top spin' and 'gyrospin', a tendency that can confuse the issue, especially if gyrospin is always poorly understood and left out. See the Sakurai, Elliott, Reid publication for definitions.
All types of serves have all three components of spin, as the ball with spin vectors diagram shows. This is a clear and complete 3D description of the spin.
Diagrams that show only 2 dimensions, posts #12 & 15, cannot show components in all 3 dimensions. For decades I thought of tennis ball spin as made up of slice and topspin. Those thoughts cannot describe a spin axis in 3 dimensions. Three dimensions is the reality as shown by the ball picture with its 3 vector components.
Tennis usage of terms such as Kick Serve and Top Spin Serve can be anything. I go with the researchers Cross and Lindsey and their views. They are described in the book Technical Tennis. Also with Sakurai, Elliott, Reid that did the research to measure the spin axes of the kick, flat and slice serves shown in the picture. They seem to be consistent with one another and make sense for 3 dimensions.
The gyrospin accounts for the sideways bounce of the kick serve according to Cross. The side bounce is larger because of the angle of the trajectory to the court. (Search: The Physics of the Kick Serve, R. Cross)
Forum posters views vs scientific researchers views....take your pick but listen to both......
I just wanted to add that, in my opinion, the benefit of topslice is that you can use also the same swing motion and follow-through (toward backhand side leg) as a flat and slice serve, but with slightly different toss location and timing of the contact. In contrast, the topspin/twist serve use a different service motion that generally includes finishing to the forehand side. So I think the topslice is often easier to learn and to disguise, as well as being more effective for shorter players (shorter player's kicker may be going into opponents wheelhouse for crushing ground strokes). Also, I find topslice to be easier on my back (less twisting of the torso). I think the topspin/kicker has developed a cache because it is generally harder to learn, so its use is limited to more skilled players and not because the topspin kicker is a better second serve. For example, almost every junior starts with a topslice second serve, so they think of it as a kid's serve.No. It's a slice serve that you hit up on a little more.

No - what I said agrees with the diagram you posted of the back of the ball.You have twist and topspin a bit confused and mixed.
The more sideway you hit it the more your kick will bounce to the right.
The obvious answer would be the slice serve, but considering it´s a trick question I guess it´s not.
The flat serve?!
question: can you put topspin on a flat serve without it being slice?
That's a good question I have been thinking of, how Peter Sampras and Andy Roddick would serve big flat first serve, but with a hard snap follow through, and it would put a spin on the ball so that it would bounce high and hard off the court at you. Hard to do.
yeah how did Roddick do it...
150mph serve at 6'2 well inside the box..
Just how
Roddick was slightly taller and his racquet was also extended length. He definitely gets great extension at contact exploding upward. Maybe he has longer arms too? All of these factors collectively make a big difference.yeah how did Roddick do it...
150mph serve at 6'2 well inside the box..
Just how
The thing is I can get cllse to the speed of him (130-140 is doable for me) but it nearly never went in, so my conclusion was that he put more topspin on the ball but I never understood how.
My height is pretty similar at 6'1

He was also probably the top 5 best server in history of the ATP tour and practiced his serve more than 100 rec players will in a lifetime, I don't get why @Jens Gabler is acting like he wants to "figure" out his secret in order to serve like him, dude ul never even get close to serving like that, almost nobody in the history of the ATP tour did
