All Farm, AA, AAA, and Majors teams need to have at least one volunteer scorekeeper, preferably a second back-up scorekeeper as well. For games, the home team provides the official scorekeeper and the visitor provides the unofficial scorekeeper. Scorekeepers must have a touchscreen device (iPhone, Android, iPad, etc.) to keep score using the GameChanger app. 

For those new to GameChanger, review the video tutorials here.
