Mobility, Flexibility & Stability Screening

Ezequiel has a “neutral” thoracic which shows up in his loading style as a hitter. He has 50 degrees of rotation to the right and 48 degrees to the left. His scapular retraction is “neutral.” Retraction was 4 inches in both scaps. He is “loose” in internal and external hip rotation.  He has core instability which limits core to lead arm transfer in the swing. This will need to be addressed with S and C.

Force Plate Jumps

Zeke has a minimal leg-to-leg imbalance in his jump tests. He favors his right leg 4%. Since the standard deviation is also 4%, it is of no concern currently.  Counter movement jumps were considerably lower than squat-pause jumps. CMJ had a lift off force at 280% BW while SJ were 340% BW. This shows Zeke prefers to transfer speed over a longer period of time.

Force Plate Swings

Below is video of the swing analysis. I will walk you through this matched up with video.

Zeke loads into the ball of his foot and but still is excellent in his back leg loading force. He gets 105% BW into his back leg load. Front leg interaction with the ground is outstanding, posting numbers over 220% BW. His rate of force production in his front leg is very high. He prefers to create vertical and rotational speed.

Back leg torque numbers are slightly lower than the 45 Nm we are looking for. Zeke is at 38Nm. Improving this metric can improve his low hip rotational values. Leg to leg transfer rates are outstanding – shown by his x-axis timing numbers.  He produces a great deal of torque force at 128 Nm.

KVEST Sequencing & Rotational Speeds

The 3d readings are on kinematic sequencing and rotational speeds.

Like a lot of players that have more than 27 degrees of inward torso rotation, Zeke tends to fire from the upper body first.   Torso inward rotation is 38 degrees which normally leads to limited energy transfer in the swing. We see the lead arm firing to start the swing because the torso has farther to open.  Despite quick leg to leg transfer, the over-rotated torso leads to a higher TTI for Zeke. Hip speeds are “fair” on the “Real Speed” scale at 635 deg/sec. Part of this is his hips decelerate over a long period of time and I’d attribute that to him having a large ROM in his IR and ER in his hips. Torso values are “fair,” at 1035 deg/sec. Lead arm values are average and often start the swing which decreases chaining speed gains. Lead arm values are at 1240 deg/sec. Wrist values are also average at 1790 deg/sec. He’s using torso rotation to stretch his thoracic and firing from the upper thoracic to propel the bat. This may be something he can exchange for scapular load and reduce his TTI.

Bat Sensor Data

Bat speed numbers ranged from 66-67 mph which is in the bottom quarter of the org. He turns the barrel early into the zone very well and gets on plane early. Attack angles were 4-14 degrees depending on the timing of ball strike, but he attacks under the ball very well. Time to impact was high at 176-187 milliseconds.

Summary & Recommendations

• Improve core stability w S and C

• Watch inward torso rotation and see if we can replace with scap load to stretch the core and help TTI that way.
