Scorekeepers can track the various innings that a player occupies during a game along with the number of innings that the player logged at each position. You will only be able to access this information from within the app while scoring. Team Staff can view up to 2 positions played by each player in the Box Score.

To review this data, select a player from anywhere within a game to view the player's Player Details. It is at the bottom of this profile page where the various innings played, and the time at each position will be listed.
