Setting the defense
The starting defense has already been set by using the Roster & Lineup Manager. The starting defense has also been set in every cell on the scoresheet. Once a game starts the RLM has nothing to do with setting a teams defense. You have to use the D key to change a teams defense after a game starts.
Press D to make a defensive change. You will usually do this at the beginning of an inning but not always. The Set Defense dialog box will appear. Make any changes that are needed. You can hold down the Alt key and press the number of the position you want to change to go directly to that drop down list. When all changes have been made press Enter. Every cell from the current cell to the end of the scoresheet will be set to the new defense.
Sometimes the Set Defense dialog box will appear automatically such as when you insert a new pitcher. In this case you can usually just press Enter as the new pitcher will have already been inserted for you.
If you ever need to edit the defense for a cell that has already been set use the X key.
