Because there is less over all movement, a lower toss and a more controlled arm swing, it’s harder to screw this type of serve up. On the other hand, you don’t get quite the velocity of a top spin jump serve.
You also get the unpredictability of a float serve sent at a higher velocity than if you delivered it from a standing position.
You can perform the baby jump serve in two ways: Using a two step approach and jumping off one foot, or using three steps and taking off two foot.
For the former, both steps will be short and quick; if the latter you’ll take one bigger step followed by the two quick ones. Right-handed players who are using three steps will use a left-right-left procedure; two steps means a right-left approach.
To get the accuracy that you need, make sure that feet, hips and shoulders area ll facing the same direction as you prepare to serve. Your approach should go in a straight line, which is in line with the path of the ball.
You’ll toss the ball with both hands, but it’s really more of a lift than a toss since the ball travels a very short distance. Because the toss is small, you need to get your serving arm up quickly. Don’t extend your arm all way; just get your elbow up by your ear and make sure your hand stays above your head.
As with the regular float serve, you want to contact the ball with the heel of your hand as evenly as possible to avoid putting spin on the ball. Use minimal follow through and keep your wrist locked.
