This is a tryout/evaluation (below is from their website)
If your Son has not been through anything like this, it is a good experience...but it is not a showcase to be seen by college coaches per se.
What Are the Under Armour National Tryouts?
Baseball Factory is conducting a nationwide search to locate the best high school baseball players in the United States.
Tryouts will be run similar to a pro-style workout camp. Baseball Factory and Team One scouts will evaluate players on various aspects of the game including speed, defense, pitching, hitting, and arm strength.
Players must register to attend. These tryouts also serve as a selection process for the Under Armour Pre-season All-America Team, Baseball Express, and Cape Cod HS Classic.
