Quickness

Quickness is vital to a hitter’s success as it is directly related to timing, and timing is key to making good contact. There is one part to the Quickness score: Trigger to Impact.

Trigger To Impact

The Science Behind It:

Trigger to Impact is the amount of time – in milliseconds – elapsed from the start of the hitter’s forward bat motion and contact. SwingTracker measures Trigger To Impact from the instant the hitter begins accelerating toward the ball until the moment of contact.

What It Means For Hitters:

A lower Trigger to Impact Time results in more quickness. Trigger to Impact is directly related to a hitter’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:

Give the hitter more time to make swing decisions
Help the hitter determine pitch location
Help the hitter time and make contact with higher velocities, as well as give hitters more time to make adjustments mid-swing

Real World Similarity

This is the amount of time it would take a car to get from its starting point to its end point. Here, the end point is the moment contact is made.

DK Pro Tip:

A bat that is too heavy can slow down Trigger to Impact Time, which will negatively affect the swing.
