Up until last year, the tryouts were sponsored by PUMA. UnderArmour took it over this year. The Baseball Factory, in partnership with Team One, conducts many such tryouts throughout the United States for the purpose of evaluating players for placement in higher profile events such as their elite Team One Regional Showcases, the Team One National Showcase, and the Arizona Senior Fall Classic. These events provide a lot of exposure to college coaches at first class facilities. The 2006 Team One West Showcase for example, was held at Diablo Stadium in Tempe, AZ, the spring training facility of the LA Angels of Anaheim. The 2006 Arizona Senior Fall Classic, one of the biggest showcase events conducted during the fall season, was held in Peoria, AZ at the spring training facility of the Padres and Mariners and attracted in the neighborhood of 150-200 college coaches from all over the country and every team from the MLB.
