Quickness is critical to a hitter’s success since it is directly related to timing & therefore one’s potential for good contact. There is one part to the overall Quickness score: Trigger To Impact.
The Science Behind It
Trigger To Impact is the amount of time – measured in milliseconds – elapsed from the start of your forward bat motion to the moment of impact.
SwingTracker measures Trigger To Impact from the instant the player begins accelerating the bat toward ball, until the precise moment of impact.
What It Means For Hitters
A lower Trigger To Impact time results in a higher Quickness score. Moreover, Trigger To Impact is directly related to a batter’s timing. According to Dr. Alan Nathan, “to get the highest home run probability requires swinging with a larger attack angle, keeping in mind that you will fail often if the swing is mis-timed.“
What It Means For Coaches
Improving Trigger To Impact time will:
1) Help the batter wait longer to identify the pitch
2) Help the batter determine the location of the pitch
3) Help the batter catch up to, and make contact with faster pitches or make adjustments mid-swing
Real World Similarity
The amount of time it would take for a car to go from its starting point until its end point. In this instance, the end point would represent the bat making contact with the ball.
DK Pro Tip
A bat that is too heavy may slow Trigger To Impact time and thus not allow one to maximize their swing potential.
