7.66
Outfield Velocity
The athlete's maximum throwing velocity from an outfield position in the given event year. Measured in miles per hour (MPH).
79.0
Power / Speed Score
A simple calculation that divides the athlete’s Exit Velocity Max by the athlete’s 60 Yard Dash time for the given event year. For example, 98 MPH / 7.00s = 14.00.
The maximum speed, in the direction of home plate, that the wrist is traveling. Measured in meters per second (m/s)
Arm Slot
Angle of the forearm relative to the ground between maximum external rotation (MER) and ball release (BR). Which can be a powerful player comparison metric, delivered in degrees.
Knee Extension Velo
The angular velocity of the front knee straightening after foot plant, which provides indicators of velocity potential. Measured in degrees per second.
Deception
The amount of time that the ball is visible to the hitter, after the instant of front foot strike. Measures in milliseconds.
Hip-Shoulder Separation
The difference in angle of between the hips and shoulders, occurring close to the foot plant. Measured in degrees.
Jahnke has a physical build and a thick, strong lower half that moves in a fluid pattern on the mound, stacking onto his backside early and quickly accelerating downhill. His arm plays long and loose on the backside while working from a clean, high ¾ slot. Jahnke’s fastball worked from a lower average release height at 81-82 mph and it aided him to create some upper-quadrant life as it entered the zone. He threw his changeup at 73-75 mph, at arm speed, flashing sink and fade, while spinning a handful of sharp slurve-type breaking balls out of the stretch at 65-66 mph.
