Creating a Player File Rotisserie or Pool Head Office maintains a master player stat file, called a “BaseBall.HO” file. As you change players statistics or import and update stats, this is the only file that is affected. Therefore having a backup of this file is strongly advised before doing any amount of changes. Before you can update or edit any players current stats, Head Office needs to create this file. Go to the menu bar and use the Player menu and use the Create Player File item.   If your league file is open, Head Office will close it for you. Once the player file is created you may import or edit player stats. You now have your league ready to generate its first report.
