Overall Efficiency Grade: 64.00
Mobility, Flexibility & Stability Screening
Levi is a “neutral” mover. He has 40 degrees of rotation to the right and 40 degrees to the left. His scapular retraction is “neutral.” He has 4 inches of retraction in both scaps. He is “neutral” in internal hip rotation and “neutral” in external hip rotation. Core stability is excellent, which will factor into his energy transfer.
Force Plate Jumps
Levi is balanced leg to leg. Counter movement jumps were nearly equal to squat-pause jumps. CMJ had a lift off force at 266% BW while SJ were 256% BW. This gives him some flexibility in choosing a loading style.
Force Plate Swings
Below is video of the swing analysis. I will walk you through this matched up with video.
Levi loads into his whole foot but creates a slightly low back leg loading force at 93% BW. He prefers to create horizontal and torque speeds, therefore vertical force is slightly low. Front leg force is 165% BW on the vertical axis.
Back leg torque numbers are at the desired 45 Nm. Leg to leg transfer rates are very good – shown by his x-axis timing numbers. This will give him needed adjustability since he doesn’t turn very fast. His horizontal and torque forces are both high as he creates speed in three vectors. He creates 140 Nm of torque force. The issue in his lower half isn’t in his speed, it’s his direction. Because he closes off his lower half, striding across his back shoe, his direction is towards the opposite field gap. He also has a traditional hip turn as he strides across, which requires elite turn speeds to clear his lower body and get to the inside pitch. He doesn’t have elite turn speeds. His lower half blocks him from getting to the inside pitch, so he has to scissor his back leg to clear his lower body or he has to land on-line with his stride in order to clear with a traditional turn.
KVEST Sequencing & Rotational Speeds
The 3d readings are on kinematic sequencing and rotational speeds.
Like a lot of players that “over-close” off their body, their upper body tends to have to fire out of sequence. He creates good turn speeds and has excellent deceleration rates. He is sequenced, but at times turns his torso inward too much versus pulling his scap back. Hip speeds are “good” on the “Real Speed” scale at 750 deg/sec. Torso values are “good,” at 1050 deg/sec and can be improved by tightening the core with a bigger scap load instead of torso turn. Lead arm values get good climb and reach 1240 deg/sec. Wrist values are good at 1900 deg/sec.
Bat Sensor Data
Bat speeds are slightly below average at 64-66mph. Attack angles tend to be steep and often negative. He’ll have to use his torso to turn under balls versus using his hands. TTI is higher than ideal at 172-183 milliseconds.
Summary & Recommendations
The issue is in his lower half direction. Because he closes off his lower half, striding across his back shoe, his direction is towards the opposite field gap. He also has a traditional hip turn as he strides across, which requires elite turn speeds to clear his lower body and get to the inside pitch. He doesn’t have elite turn speeds. His lower half blocks him from getting to the inside pitch, so he has to scissor his back leg to clear his lower body or he has to land on-line with his stride in order to clear with a traditional turn.
