Team Last Played

WHAT IS IT?
Team Last Played is the team with which the player last attended a PG tournament. It will be updated when the player is rostered and attends with each team.

MAX BARREL SPEED

WHAT IS IT?
The maximum speed of the sweet spot of the barrel of the bat during the swing. The sweet spot is 20% of the bat length from the tip of the bat.

ON-FIELD IMPACT
High bat speed produces high ball exit speed, so increasing your barrel speed is an important goal. Keep in mind that you need to “square up the ball” to maximize your ball exit speed.

IMPACT MOMENTUM

WHAT IS IT?
The momentum your bat has at impact. Impact momentum is a combination of the barrel speed at impact and the weight of the bat.

ON-FIELD IMPACT
Increasing your impact momentum directly translates to a higher ball exit velocity. Higher impact momentum means better potential for further hits and higher exit velocity.

MAX ACCELERATION

WHAT IS IT?
The maximum acceleration the bat experiences during the swing, measured in “g’s”. To be clear, acceleration is not how fast the bat is moving; that’s barrel speed. Acceleration determines how quickly you can reach that top speed.

ON-FIELD IMPACT
More acceleration means that you can reach your max barrel speed quicker. Higher acceleration lets you wait a little longer before you decide to swing, and in some cases means that you can maintain higher bat speed for more of the swing.
