Athlete's run in short bursts 5 yards to the left, changes direction and run 10 yards to the right, then pivot and explodes 5 yards back to the left finishing where they started. The shuttle run tests an athlete's lateral quickness, explosion in short areas and ability to change direction.

The athlete starts from a still place, crouches, rocks back and leaps forward on a horizontal plane. This measures lower half strength, hip mobility and core strength.

Using a dynamometer, we test for grip strength by having an athlete squeeze the device as hard as they can for a few seconds. In general, the stronger an athlete's grip the quicker their bat speed and throwing velocity.

Also known as Pop Time, this test is measured using a stopwatch. The catcher receives a pitch, exchanges, and throws down to 2B. The timer starts when the ball contacts the Catcher's glove and is stopped when the ball contact's the middle infielder's glove at 2B. Combining technique, agility, and arm strength, Pop Time is one of the most important metrics for a Catcher because it indicates their ability to throw runners out.

The player throws a ball as hard as they can off the crow hop into a net and the velocity is captured using a radar gun.

The batter hits a ball off a tee and we use a radar gun to capture the velocity of the ball coming off the barrel of the bat. This test gives an idea of an athlete's bat speed, explosiveness, hand speed, and overall strength.

The arm grade takes into consideration a variety of components including the initial trajectory (speed and angle upon exit from the hand), the raw radar velocity (measured in MPH), the carry or flight of the ball (what the ball is doing in the air), and the action and accuracy of the ball into the target (speed and angle upon arrival).
