  • Sampras serve notes.

    He does not begin the leg drive until the stick is almost at vertical, there is a large time lag inbetween, as the toss is up, the motion starts, but, slowly, as then the drive up starts, while the stick only after the leg drive has already begun, then it starts its whipping motion down to trophy position.

    He arches his back, so the shoulders form a straight line right before driving up, and they exchange positions, rotating extreme from full external to fully internal.

    He moves forward from all weight back at the start, to a knee bend, with the archers bow/left hip out over the baseline, so the hip moves about 18" from the rear to the baseline even before he leg drives up...

    He comes at the ball in a tomahawk, then pronates all the way over, a full 180 or more degrees...

    He uses a stiffer version of that frame.

    He uses a lot of lead, 12 pieces of 1/8" lead at 3 and 9, which stretches 12 cross strings.

    He uses the j toss, then the stick starts to go up, but only after the shoulders are already turned to the back fence, and the toss is up 2-3' higher than contact point which is 2-3' in front of the baseline...

    He externally rotates his stick shoulder, so it is cocked all the way towards the net, but does not crowd the stick arm/elbow.

    He reaches towards the left net post with his stick, while leg driving up.

    He tosses 2-3' in front and hits the ball at an 11 oclock position.

    He goes from full radial to full ulnar deviation on his wrist, with the stick facing the side fence, the hitting bed.

    He pronates foward, and stops his elbow, so the stick rotates down precipitously, but does not snap down, but forward and only ends up down as an effect of the forward wrist deviation.

    He scrunches up his left lower back, to make his shoulders form a line up and down as they rotate.

    He stops his shoulders/hips from rotating past a point: 90 degrees towards the net..

    He starts his left hip rotating before anything else, and twists his torso/hips/shoulders very fast forward, a full 90 degree rotation.

    He uses a stick that weighs 384=-389g total mass, with vs all season gut at 73lbs, and had it at 59lbs earlier in his career.

    He pronates the same regardless of flat/slice/kick serves, so the bed is facing the side fence, just hits a diff. part of the ball for placement/spins.

    He uses a very fluid, tireless motion, which rhythm is smooth and unmuscled, very easy to reproduce.

    No one can copy the motion or its rhythm, due to its extreme coil, yet easy timing, and the full use of shoulder external/internal rotation, increased by an easy leg drive upwards, not forwards, and a full wrist deviation which caused a maximum rpm on his serves, adding weight/heaviness to them, an average of 2900 rpm on firsts, and 4800 rpm on seconds. The leg drive off the ground, added to the shoulder coil, added to the kinetic voltage like a whip cracking the snap back forwards..

    The only way for me to learn this, is the video camera, practice the motion first, without a racquet, and focus on learning the kinetic rhythm first.

    __________________IF you have ever tried to volley with a stick that weighs 389g, you would know just how hard it is to maneuver at net. Sampras could do it due to how many sitters his serve caused. My serve, at that weight, I had a lot of trouble just moving the frame at net. Returns were uncontrollable as well. Serves had more power, but the weight caused injuries.

    The frames 1-4, show the leg drive correlating to the racquet drop. Full knee bend is attained, and movement to the line, with archers' bow, as stick assumes vertical, and then the leg drive occurs, and expends itself, just as the stick assumes the lowest point in the trophy progression, and the stick does not accelerate until it reaches a point above the shoulders.

      This might be of interest also. The dots represent racket head speed of the Sampras serve.

        Nice. Have not seen that. You are a finder of good things.

          Note how the really big acceleration occurs half way up from the racket drop, just prior to impact....

            He also rocks his upper arm/shoulder forward, as the stick goes back, and then rocks the upper arm backwards, as the frame pronates, like a high speed rocking chair, using that rhythm to gain speed and mass, and uses the forearm to pronate.
