Having some problems with aiming my serves

Lately, I frequently ended up hitting wide flat slice serves when trying to hit a down the T flat serve on Deuce court. Same thing happened when serve on AD court as well. I kinda struggle to aim my serves. I am looking for some advice here.

It’s all about body geometry. If you want to go down the T on the deuce court you need to line up more side on with left hip, shoulder and racquet pointing down the middle of the court.
Ball toss at 1 o’clock and not too far ahead with back straight and back foot stability will fix your problem easy.

I'll tell you what I used to do for my serve practice. I would set up cones and create three lanes in each of the service boxes(Wide/Body/T). Practice placing your serve in each lane. Give yourself 3-4 balls for each lane and see how many you can place. Placing a serve definitely requires good mechanics and technique, but once you start developing muscle memory of your serve placement, it'll be much easier.

That's part one, work on that first. Next step is to place tennis cans in each lane and aim to hit each one. Same thing, give yourself 3-4 balls to hit each can. One last suggestion, if you have one available, have teaching pro or coach take a look at your serve for feedback.

Do you mean my body needs to stay sideway more?

Sure. But I believe that I should be aware of the difference in swing paths and body rotation between say, a wide serve and a T serve on Deuce court, before practicing.

First, you should video your serve technique and determine the technique that you are using.

The high level serve uses internal shoulder rotation so that the face of the racket rotates clockwise when viewed from above. That rotation occurs at the shoulder joint and causes the upper arm to rotate. This racket face angle at impact affects the side-to-side placement of the serve. A high speed video will show you why you are hitting to one side or the other.

Signature of tennis serve.


You can see the rotation of the racket in the side-to-side direction between the red arrows. The path of the hand and racket head center relative to the ball's trajectory is also clear from this camera angle (looking mostly along the hand path). To examine this you need high speed video of your own serve for feedback. 240 fps, small motion blur, and bright sunlight works with many smartphones.

A close up during impact shows both the same clockwise rotation from ISR plus the racket face closing as it move forward. 6,000 fps.

Another view from above showing the effect of ISR on the direction of the racket face at impact for slice, flat and kick serves.


If you have another technique that might show the problem also.

Have you recently changed your serve?


Note- 'Closed' means that the highest edge of the racket face is farthest ahead. 'Closing' means a rotation toward more closed. The reference direction is the direction of gravity.

How is your throwing accuracy? And how is it impacted by how fast you're throwing?

I suspect your throwing accuracy is fine when throwing slowly. But if you try to throw at 100%, your accuracy will suffer. Maybe that's what's happening when you serve.

As a test, try serving from the SL [not the BL] at 70% and note your accuracy.

Start moving back incrementally towards the BL and keep the power the same: can you reach the BL and maintain accuracy?

If yes, then you're having problems controlling your power. Maybe you're trying to muscle the ball too much, which requires tension which will sabotage your accuracy.

If no, then you need to work on this before adding back the power.

In other words, find exactly where your breakdown is and zoom in to that area.
