## APPROACH ANGLE

There are three parts to Diamond Kinetics’ overall Control metric – Hand Cast Distance, Distance In The Zone and Approach Angle.

### THE SCIENCE BEHIND APPROACH ANGLE:

Approach Angle assesses three different types of swings: 1) An ‘upper cut’ swing – which results in a positive approach angle, 2) a ‘chop’ swing – which results in a negative approach angle or 3) a ‘level’ swing – which results in neither a positive or negative approach angle. It is measured at the moment precisely before contact.

### WHAT IT MEANS FOR BATTERS:

To hit a fly ball, you would likely want a slightly positive approach angle. To hit a line drive, you would likely want an approach angle near zero. To hit a ground ball, you would likely want a negative approach angle.

REAL WORLD SIMILARITY: As a plane takes off from the runway, it is ideal for the plane to angle upwards in order to ascend into the sky. In contrast, for a plane to land on the airport runway, it is ideal to angle downward in order to descend before it comes in contact with the ground. Once in the air, if the plane wanted to maintain a steady flight, not up or down, it would fly at a level angle. These same simple principles apply to Approach Angle, relative to the angle of the bat right before impact and how that determines the flight of the ball.

### WHAT IT MEANS FOR COACHES:

Having Speed, Quickness and Power does not mean very much unless a player can put the bat on the ball. As such, each of the Control metrics, including Approach Angle, are key in order for the player to maximize their strengths in the other three areas (speed, quickness, power) of SwingTracker

DK TIP: When trying to hit the ball a specific way in a game (i.e. – a sacrifice fly or a ground ball to move the runner up a base), Approach Angle is a vital tool in terms of achieving that goal. SwingTracker allows you the ability to practice the specifics of each type of swing that would be demanded in such a situation.
